PHP :: Array Sort: Multidimensional Arrays?

Multidimensional Arrays Appropriate For This?
I'm writing a class to obtain package tracking information for UPS. They provide a tool that will do this with xml. I submit a query in a specific format and it returns an xml document, which I then parse with some other functions.

The response contains information on the package's location (city, state, zip) and its status (delivered, in transit) and the date & time of each entry.

It is possible for one package to have an array of values for location, status, time & date because it is always moving. So, for example, I might get an array of 10 results that provide info about the shipment from start to finish.

Currently, I'm storing each value (city, state, zip, delivered/in transit, time, date) in its own array. So, there's an array of 10 elements for city, another for state, and so on.

I'm wondering if it's appropriate to have a single multidimensional array instead of one array for each piece of info. The columns would be each individual piece of information (city, state, zip, ....) and the rows can be the number of entries of each piece of information (in my example, 10).

My array would then have 10 rows with the required number of columns, each showing the data for that entry.

Is this a good solution, or should I stick with one array for each piece of information?

Multidimensional Arrays
I'm having trouble working with Multidimensional Arrays. Does anyone
have any tutorials or links they might share on the topic. The
challenges I'm having are sorting by a value in the 2nd array and
searching for a value in the second array.

Array
(
[0] => Array
(
[id] => 6
[answer] => A
[remote_address] => 24.15.143.7
[date_time] => 2006-06-20 07:35:24
[survey_id] => 1
)

[1] => Array
(
[id] => 4
[answer] => B
[remote_address] => 24.15.143.7
[date_time] => 2006-06-20 07:35:24
[survey_id] => 1
)
)

I'm just not getting how the php example works with usort() or
array_filter().

PHP 5 + COM + Multidimensional Arrays
I'm trying to make use of a certain method of a COM object that takes a
multidimensional array as its sole parameter.

Here's an example of the construction of said array:
$cA = array();
$cA[$adjNum][0] = new VARIANT($cDesc);Type Code
$cA[$adjNum][1] = new VARIANT($cLongDesc);Long Description
$cA[$adjNum][2] = new VARIANT('B');
$cA[$adjNum][3] = new VARIANT($cPrice);
$cA[$adjNum][4] = new VARIANT('D');
$cA[$adjNum][5] = new VARIANT($i);

$result = $awfulComObject->SetAdjustments(new VARIANT($cA), new
VARIANT('D'));

The method simply never works out. The COM object on the other end
always says 'Invalid data array'.

I've tried all varieties of messing around with this: casting the
variables in the array to variants (and not doing so), casting the
array itself to variant (and not doing so)... etc...

Does anyone have a better way of constructing a multidimensional array
that works with COM in PHP?

It's rumored that PHP 5 allows for the passing and reading of arrays to
and from COM objects (http://us2.php.net/com)...

"PHP 5 introduces the following new features to make your life
easier: *Access multi-dimensional arrays, or COM properties that
require multiple parameters using PHP array syntax. You can also write
or set properties using this technique. "

About Sessions -multidimensional Arrays
I have realized that sessions do not always update if holding much data, for example if they contains multidimensional arrays.

Does anybody knows why and how to get around this.

Sorting Multidimensional Arrays
I am trying to analyse stored customer enquiries by month and country of origin. The total enquiries for each country and month are contained in an array in the format...

$country[$x][$z]

...where $x is the month (1-12) and $z is a country code (1-200).

I need to list the contents of the array by month, in ascending order, and by the value of the country column, in descending order.

I have spent a day trying to get my head around the various array sort functions and failed miserably.

Foreach With Multidimensional Arrays
Can foreach() be used to loop through a multidimensional array?

Sorting Multidimensional Arrays
How would I go about sorting the following array, I've been looking at array_multisort but to be honest I'm either not fully understanding it or it's not capable of what I'm trying to do.

What I'd like to do is to sort the array by the values in array[$i][0] but I can't figure it out, the values being zzzz,a0,a1,00000000000000. PHP Code:

Looping Through Multidimensional Arrays
I have a 2D array, which I am trying to access, but I am having
problems doing this:

If, for instance, I use a nested for loop to go through the values,
using something like

echo "$MyArray[$loop_var_one][$loop_var_two]";
I get the following:
Array[1]
Array[2]
Array[3]
etc.

If I do a var_dump($MyArray[$loop_var_one][$loop_var_two])
I get
string(1) "2"
string(1) "0"
string(1) "3"
etc.

Now, if I do a count($MyArray[$loop_var_one]);
to see how many array elements are in the 2nd array index (for the
for...loop), I get zero!
Also, if I do the following
$new_array = $MyArray[$loop_var_one];
to try and populate a second array, and then do a var_dump(
$new_array), I get nothing as well.

Searching Multidimensional Arrays
is there a way to search an array so it goes all the way down even if an element of the parent array is an array. that is w/o any loops i tried in_array but that doesnt do it. i dont think array_search does either.

Dynamic Multidimensional Arrays
I am having trouble properly setting a dynamic variable that should be part of an array. Code:

Multidimensional Arrays Count
I really need some help with this, heres the code I got

$Tshirts = array(
'1' => array('Tshirt Name 1', 'S'),
'2' => array('Tshirt Name 2', 'S'),
'3' => array('Tshirt Name 3', 'M'),
'4' => array('Tshirt Name 4', 'S'),
'5' => array('Tshirt Name 5', 'S'),
);

to display this code, I used the following

$i = 0;
foreach($Tshirts as $id_num => $name)
{
i++;

echo '<a href="/view?id='.$id_num.'">'.$i.': '.$name[0].'</a>';
}

and my question is how can I get the total number of Tshirts labelled Medium (M) or Small (S) in my arrays? Because I wanna create columns, such as:

A F
B G
C H
D I
E J

etc. ...but I need the total number of M's and S's so I know when to insert a break.. because right now its just a straight line going downward:

A
B
C
D
E
F
G
H
I
J

It figured out how to get it to display like this:

A B
C D
E F
G H
I J

..but that's not the way I want it I hope this makes sense lol.. I just can't figure out how to do it.. count($Tshirts) won't do much in this case Anway, I'd really appreciate it if someone could help me with this.

Directory Recursion And Multidimensional Arrays
I have created a script which recurses a display of directories like
so:

<?
$dir = "/path/to/base/directory";
function scan_dir_recurse ($dir,$tab)
{
global $fileArr;
$tab++;
if ($tab 4) { exit ("Tab length exceeded."); }
$files = scandir($dir);
for ($i=0; $i<count($files); $i++)
{
if ($files[$i] != '.' && $files[$i] != '..')
{
echo str_repeat(" ", $tab-1).$files[$i]."
";
if (is_dir($dir.'/'.$files[$i]))
{
scan_dir_recurse ($dir.'/'.$files[$i],$tab);
}
}
}
}
scan_dir_recurse($dir,0);
?>

What is want to do is generate a multidimensional array which will be
accessable on a DHTML page of select boxes where, a user first selects
a top directory, then a select box appears of directories under it,
etc. until a list of available files is available.

For example:
$fileArr[0] = 'dir1'
$fileArr[0][0] = 'dir2'
$fileArr[0][0][0] = 'dir3'
$fileArr[0][0][0][0] = 'a_file'

The solution to adding another level of recursion to the array escapes
me at the moment.

How To Slice Multidimensional Arrays By Row Values?
From a DB query, I receive the following result set:

array(array('key1'=>'some val', 'key2'=>'some other val', ..., n),
array('key1'=>'some val', 'key2'=>'some other val', ..., n),
array('key1'=>'some val', 'key2'=>'some other val', ..., n),

Sorting Multidimensional Arrays On A Named Dimension?
I usually store info in arrays using field names

$array[1]["country"]='Germany',
$array[1]["code"]="GE";

$array[2]["country"]='United Sates"
$array[2]["code"]="US";

$array[3]["country"]='France"
$array[3]["code"]='FR"

I want to get:
$array[1]["country"]='France"
$array[1]["code"]='FR"

$array[2]["country"]='Germany'
$array[2]["code"]="GE";

$array[3]["country"]='US"
$array[3]["code"]="US";

Is there a function to sort on a field (country in this case)

Combine Two Arrays? Well, Sort Of...
I am a relative PHP newbie and I am trying to combine two arrays together,
but I also need to keep the keys of one array intact. What I am doing is two
SNMP walks against a Cisco router in which I expect the script to return the
interface number along with a small description of the interface type, like
this:

Array
(
[IF-MIB::ifDescr.1] =Serial0
[IF-MIB::ifDescr.2] =FastEthernet0
[IF-MIB::ifDescr.3] =Null0
[IF-MIB::ifDescr.4] =Loopback100
)

I also am doing another SNMP walk to gather the user-defined description of
each interface (which is keyed off of the interface number). Here is the
output I get from that:

Array
(
[OLD-CISCO-INTERFACES-MIB::locIfDescr.1] ="PPP T1 to Customer"
[OLD-CISCO-INTERFACES-MIB::locIfDescr.2] ="Ethernet to LAN"
[OLD-CISCO-INTERFACES-MIB::locIfDescr.3] =""
[OLD-CISCO-INTERFACES-MIB::locIfDescr.4] =""
)

I would like to combine the arrays, but I would like to preserve the keys
and values from the first array, but also append the values of the second
array (don't really care about the keys, they *should* line up).

I looked into the array_combine function, but that takes the values from the
first array and makes them the keys for a new array.

My ultimate goal is to output this to an HTML table, but the data is not
lining up as I expected since when I join/combine the arrays, I lose my
keys.

Using Arrays To Sort Posts
I'm trying to sort my posts so that they are grouped and seperated for every month. For example all december posts will be grouped togther and given a header with the name december, and etc for the other months. Code:

How To Sort Multiple Arrays?
I have two arrays, $arr1 and $arr2.

Values in the first corresponds to the same index-values in the second.

How do I sort these array's ascending according to $arr1?

Multidimensional Array Syntaxt For Preg_split Array Using Submitted Textarea
I have two textarea's called textarea1 and textarea2. What i did was use preg_split to split the textarea into seperate rows that i could use for analysis like so

$array = preg_split("/[
]?[
]/", $_POST['textarea2'], -1,PREG_SPLIT_NO_EMPTY);
$array2 = preg_split("/[
]?[
]/", $_POST['textarea1'], -1, PREG_SPLIT_NO_EMPTY);

then i used a function created for me by a nice guy on here called get_ending($filepath) which basically stripped off of each peice of text the "http://www" from every URL i put into the textareas

finishing off i wanted to create an array that would input an expression such as:

echo "<a href='$array[1]' target='_blank'><img src='$array2[1]' border='0'>";

into a text area on the next page. ALL of this works, except that i dont know how to properly loop throught he array so it'll properly insert the text into the textarea on the next page.

For now, all it does is place the array information in the page, rather statically, i would like to run some kind of if then statement that says

"while $array has some kind of text in it, keep running this operation of echoing the following expression adding 1 to the end of the array number" I hope that makes sense

Any ideas? Code:

Passing Array Of Multidimensional Array To Function
How do I pass a part of a multidimensional array to a function. I have the following (in pseudo):

$arrays[m][n]; // filled with values
$chosen = 3;

function doSomething($array) {
// do something with 1D array
}

This fails:

doSomething($arrays[$chosen]);

Can someone explain to me why? And how to do this right?

Sorting Sql Results In An Array Using Things Outside The Array To Sort Them?
I'm using PHP to connect to a database full of place names, and their associated post codes, latitude and longitude on the earth. A user types his or her post code into a form, plus a distance (in miles), and the script looks for other area codes (first half of the post code) within that distance.

I can do that fine, but the results are ordered alphabetically by postcode, and I want to order it by the distance. Problem here, is that the distance isn't part of the array taken from the database, it takes the latitude and longitude of the area it's on in the while loop, and calculates the distance between the user's post code and that one, but it's not part of the array, so I can't sort the array using it.

How can I sort it? Can I add the calculated distances to the array, and sort it using sort()? If yes, how do I add them to the array?

Here's the page, just to explain better what the script does: http://navimaker.org/ed/owain/results.php?postcode=gl15&distance=34
Mess around with the postcode and distance vars.

I'd put the source on here too but I'm doing all this over SSH and can't copy & paste very easily .

Multidimensional Array: See If 1st Key Is Available
I've got an multidimensional array
$ret = $country_code[$countryCode][$langCode];

Now I want to see if $countryCode is even in that array, because if it's
not, it doesn't make many sense to look further for $langCode.

Eg.

$country_code = array('BE' =>
array ('en' => 'Belgium',
'nl' => 'België'),
'NL' =>
array ('en' => 'Netherlands',
'nl' => 'Nederland'),
);

Searching for 'BE' would make sense, but 'LP' wouldn't.

I already tried:
$arr = array($country_code['LP']);
if (sizeof($arr) == 0)
print "LP not found!"

But that doesn't seem to work :-s.

Multidimensional Array
I won't post my exact code since the project I'm working on is HUGE and I'd have to explain it all anyways, but I'll provide examples. Basically, I'm using OOP PHP to build this project... and at one point I have the constructor of 'Class1', calling another method of the same class. In that method, I want to add to a multidimensional array defined in the class itself... in the first position I want to store a string, in the next position, I want to store an instance of another class.

Now, the problem I'm having is that when I try and define the multidimensional array, it takes FOREVER!!!! Literally 25 seconds! All I'm doing is this: PHP Code:

Multidimensional Associated Array
I try to construct an array such that each element of it is another
array returned by the fetch_array_function:
for ( $i = 1; $i<=$n; $i++ )
{
$ar[$i] = mysql_fetch_array( $result );
print "$ar[$i][fieldname]
";
It prints "Array[fieldname]".
If I replace $ar[$i] by $ar everything works fine! Could you pleas...

Multidimensional Array
I have an array that looks like this:

Array
(
   [0] => Array(
[fieldID] => 001
[description] => Hi all!)
   [1] => Array (
[fieldID] => 002
[description] => It’s me again! )
)
And I want to change it into array that would look like this:
Array
(
   001 => Hi all!
   002 => It’s me again!
)

Is it possible to do it at all?

How To Reference An Array In Multidimensional Array?
How do I reference an array within an array?

$mapped_array = array_map(null, $data_array, $counter_array);

// okay, so now I have an array of 2 arrays - but how do I reference each
array?
// the next two lines fail to give an accurate count
echo "Starting with ".count($mapped_array[0])." elements in
data_array ";
echo "Starting with ".count($mapped_array[1])." elements in
counter_array ";

// now I want to start at the bottom and look for an IP in each line of
data_array
// which I assume is mapped_array[0]
for ( $i=count($mapped_array[0]); $i > 0; $i-- )
{
$data_line = $mapped_array[0][$i];
$data = explode("|", $data_line);
if( in_array($ip, $data) )
{
// if there's a match, element[$i] of both arrays needs to be spliced
out
array_splice($mapped_array,$i,1);
}
}
// again, these next two lines fail to return an accurate count
echo "Ending with ".count($mapped_array[0])." elements in data_array ";
echo "Ending with ".count($mapped_array[1])." elements in
counter_array ";

Is there something about array_map that prevents me from referencing the
arrays within the array?

Problems Using Multidimensional Array
I am trying to understand multidimensional arrays within PHP, and am trying to do the following:

$x[1][1]="test";
$x[1][2]="test2";
$x[2][1]="test3";
$x[2][2]="test4";
print ("$x[1][1] $x[1][2] $x[2][1] $x[2][2]");

but instead of getting the result:
test test2 test3 test4

I am getting:
Array[1] Array[2] Array[1] Array[2]

Can someone please explain why this is happening.

Break Down Multidimensional Array
I have a multidimensional array and was wondering how it can be broken down...

Array
(
[0] => Array
(
[0] => Array
(
[0] => 1
[intsch_id] => 1
)

[1] => Array
(
[0] => 2
[intsch_id] => 2
)

)

)

And I want to break it down to

Array ( [0] => 1 [intsch_id] => 1, [1] => 2 [intsch_id] => 2) And this is in a dynamic query, so the results won't always be this simple. It will have the same structure as the above multidimensional array.

Create A Multidimensional Array From XML Doc
Currently I have the following XML document:

<Programs>
<Program>
<ProductTypeName>30 Yr Fixed</ProductTypeName>
<Rate>6.250</Rate>
<APR>6.274</APR>
<InvestorName>Helos</InvestorName>
<Payment>2832.298</Payment>
</Program>
<Program>
<ProductTypeName>30 Yr Fixed</ProductTypeName>
<Rate>9.250</Rate>
<APR>9.293</APR>
<InvestorName>Avalon</InvestorName>
<Payment>3784.306</Payment>
</Program>
<Program>
<ProductTypeName>5/1 Arm</ProductTypeName>
<Rate>6.375</Rate>
<APR>6.399</APR>
<InvestorName>Carl1</InvestorName>
<Payment>2869.802</Payment>
</Program>
</Programs>

I load it up in a domdocument and iterate through it with the following:

$returns = array();
for($i = 0; $i < $xmlproducttype->length; $i++)
{
$returns[$i]['ProductTypeName'] =
$xmlproducttype->item($i)->nodeValue;
$returns[$i]['InvestorName'] =
$xmlinvestorname->item($i)->nodeValue;
$returns[$i]['Rate'] = $xmlrate->item($i)->nodeValue;
$returns[$i]['APR'] = $xmlapr->item($i)->nodeValue;
$returns[$i]['Payment'] = $xmlpayment->item($i)->nodeValue;
}

Giving me the following style array:

Passing Multidimensional Array Thru The URL
I have an issue with an array that I would to pass to a second php
script; please note that I cannot use session.

I have been looking at the functions : rawurlencode / rawurldecode
urlencode / urldecode but it does not seems to work for my variable

here is an example of variable:

<?
$x=0;
$data[$x][title]="My title";
$data[$x][label]=array("label1","label2","label3");
$data[$x][data]=array(100,150,145);
?>

How can I pass this variable thru an URL?

How To Return A 'sub-array' Of A Multidimensional One
I have a multi-dimensional associative array, and I'm interested in searching the array for a given key, and returning the 'sub-array' or value associated with this key. for example:

Code: $array = array( 'A'=>1, 'B'=>2,
'C'=>ARRAY( 'A2' => 'FRUIT', 'B2' => 'VEGGIE',
'C2' => ARRAY( 'MEAT1' => 'BEEF', 'MEAT2' => 'CHICKEN' ) ) );

I want to retrieve the array under the key 'C2'. I have tried to 'search' the array so that its internal pointer is pointing at this element, then using 'current', but that doens't work: Code:

array_key_exists( 'C2', $array );
var_dump( current( $array ) );

I've also tried a small variation of the above in order to get the reference to C2 rather than a deep copy: Code:

array_key_exists( 'C2', $array );
var_dump( $array[key($array)] );

I would actually prefer to get a reference into the array rather than a copy.. I guess I'm really stuck on the 'search' part of the mutlidimensional array.. Surely there's a better way (built-in function) than iterating every element and comparing the key?

Multidimensional Array Merge
I need one solution for multidimentional array merging option using php. Please send me any samples multidimensional array merging.

Single Array To Multidimensional
I have a string, comma separated, with links and their respective URLs
in it. Example:
Google,http://www.google.com,Yahoo!,http://www.yahoo.com,WikiPedia,http://www.wikipedia.org

etc, etc.

i make an array of this with explode( ',', $string );

now what i wonder is how can i turn this array into something like
this:

$array[0]['name'] = Google
$array[0]['url'] = http://www.google.com
$array[1]['name'] = Yahoo!
$array[1]['url'] = http://www.yahoo.com
$array[2]['name'] = WikiPedia
$array[2]['url'] = http://www.wikipedia.org

I hope/think this is all clear ...

Multidimensional Array Loop
I am trying to loop through a multidimensional array shopping cart stored in a session. I can loop through it ok but the problem is that when the page displays I have two each of the items in the cart. I am looping through with a double foreach.

If I do print "$key: $value"; inside of the second foreach I get the correct display of the items in my cart but then the actual display of the items gives me two of each. Code:

Multidimensional Array Declaration In Php
how to achieve that? it seems php doesn't support it well for a C

Checkboxes In A Multidimensional Array
I found this nice code online that does exactly what I want it do to: Emails a form that includes the posted values. I can get the text boxes, text areas, and radio buttons to send; however I cannot for the life of me figure out how to get checkboxes to send. It will only send the last-checked value. I have searched the internet and seen that this is a common problem, but I have not found anything similar to the code that I am using. Code:

Sorting A Multidimensional Array
I Have an array set as so:

$temparr[$i]['score'] = 3.4
$temparr[$i]['id'] = 1
$temparr[$i]['title'] = 'title'

$i loops the array populating it, but when I output the array, i would like to sort it by the 'score' value asc or desc, depending on what i want to show... what is the easiest way of achieving this?

Deleting Multidimensional Array
if i have a multi dimentional array, eg:

Foreach() Multidimensional Array
I did a search for other foreach() problems and cant seem to find a solution that fits my syntax, probably because I'm a newbie. Here is my code:

Jump Out Of A Multidimensional Array?
trying to get out of an array dynamically.

$transport = array('foot', 'bike', 'car', array('test1', 'test2'));
i'm in test2( $transport[3][1] ), how do I go into $transport[3]? Is there a function capable of doing this?

Adding To Multidimensional Array
I'm realtively new to PHP and I'm trying to get my head around a particular issue. I've got an array that looks like this:

$field_array = array (
array (field=>"dist_Company", type=>"text"),
array (field=>"dist_Active", type=>"select", options=>array(array(oname=>"yes", oval=>"1"), array(oname=>"no", oval=>"0"))),
array (field=>"dist_CompanyID", type=>"select"),
array (field=>"dist_Shipping", type=>"text")
);

What I'm trying to figure out is how to add to this array after it's been defined. In this case I'm trying to add the "options" subarray to dist_CompanyID element so that it has options similar to those predefined in the dist_Active element.

I can do it if I specify the index like this:

$field_array[2]['options'][] = array(oname=>"one", oval=>"1");
$field_array[2]['options'][] = array(oname=>"two", oval=>"2");
$field_array[2]['options'][] = array(oname=>"three", oval=>"3");

Is there some elegant way to find the index number for the element containing field=>"dist_CompanyID"?

Sorting A Multidimensional Array On Two Columns
I'm working on some low-tech sort of content managing system. It uses textfiles as a kind of database so the users don't have to install SQL on their server. Now I want to perform some sorting on my files. These are the contents of one of those files.

PageName;Template;Menu;Sub;
Introductie;1;1;1;
Opnemen;1;2;0;
Voorbereidingen;1;2;2;
Kwaliteit;1;1;0;
Blabla;1;2;1;

I first read this file into $someArray with file() and then I parse each row with explode() into columns. So $someArray[2][2] contains the value 2 and $someArray[0][2] contains "Sub".

I want to sort this array on both Menu and Sub and write it back to the file. It should look like this.

PageName;Template;Menu;Sub;
Kwaliteit;1;1;0;
Introductie;1;1;1;
Opnemen;1;2;0;
Blabla;1;2;1;
Voorbereidingen;1;2;2;

I want to make a list of menus and their listed submenus in the proper order, as you can see .

What is the clever way to do this? At this moment I use a loop that sorts the submenu in a loop that finds the right menu in a loop that sorts the menus. No, it's not you, I don't understand it myself anymore. That's because I don't understand most of the array principles and functions.

Copying A Multidimensional Array To $_SESSION
Specifically, is it possible to copy a multidimensional array into the
$_SESSION array - ie a deep clone of all keys and data?

I naively assumed that

$_SESSION["myArray"'] = $myArray ;

would work but it doesn't appear to work. Is there a single function
or assignment I can use, or would I need to use a "foreach" at every
level?

Multidimensional Associatve Array Problem

Multidimensional Array Using A Recursive Function?
I have to use a recursive function to extract the data from my database. I have scoured the web but can't find any good examples to this challenge. My main obstacle is building the array. The idea is to build an array that could potentially have endless sub arrays.

Multidimensional Array - Search For Relationships

Multidimensional Array In To A MySQL Table
Trying to load an multidimensional array into a MySQL table with columns as
follows,

level1,level2,level3,illust,item,description,partN o,qua,price,remarks,weight
,size,mass

the array first line is $input[0][level1]Engine
the array secondline is $input[0][level2]Cylinder Head
etc..

A 'foreach' inside a 'foreach' echo of the array gives the following, which
is correct.

0, level1, Engine
0, level2, Cylinder Head
0, level3,
0, illust, 001.pdf
0, item, 1
