PHP :: Create Multidimensional Array Dynamically

Dynamically Adding To Multidimensional Array
$sql= sql query
$i=0;

while
($a2=mysql_fetch_array($a1)){array_push($temparray ,$a2[0],$a2['ad'],$a2[1],$a2[1]);
{
I want this array to be the value of an asssoc. array $results[$i]
$results[$i] =$temparray doesnt work
$results[$i] =$temparray[] doesnt work
$results[$i][] =$temparray doesnt work
$results[$i] =>$temparray doesnt work

then $i++;
}
so what does ?

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:

Dynamically Create New Web Page
i'm making a cms, and I have a good portion done, I have it set up where the admin can log in and create a new post which goes to the database. I am just wondering how I can make this post a new web page? I have been trying to study how they do it in wordpress but with no avail. Anyone have any suggestions?

Dynamically Create And Save Php Page
Here is my code:
$filepointer=fopen("http://www.mysite.org/usersetup/newusers/" . $SESSION_UID . "/configsite.php", "w+");

$data = "<? $name = ' . $datatosave. '
?>";

fputs($filepointer, $data);

fclose($filepointer);

My goal is to dynamically create a .php file with the contents of
<? $name = "variable data"; ?>

My code doesn't work. Something with the php page, I think. I and using similar code to populate .txt files with dynamic data, without variables, and it works file. Apparently, a quick change to .php is harder than I thought. I"ve even tried sending a simple line of data to the php page with no luck. Heck, I even tried doing it as a text file and rename to .php but it didn't like my rename.

How To Create Many Pages Dynamically From A Template?
Is there a way to create many pages dynamically... say using a template? I've over 110 html pages with the same format and I'm sick and tired of creating new pages, updating old ones, with content and links. I've access to linux and unix, php, perl, and java...
Any suggestions?

Dynamically Create Every Combination Of Words Possible
I'm trying to write a function that will begin by splitting a sentence up into an array that contains one value per word in the sentence. It should continue by creating new sentence fragments: one sentence fragment for every combination and permutation of those words. For example, if I have a sentence "I love bees," I need the function to output the following.. Code:

Dynamically Create And Access Variables?
I am trying to dynamically create new variables, and add values to those variables. In Flash, I would do so like this:

for(i=0;i<10;i++) {
var this["happy" + i]:String = "I am so happy.";
}

trace(happy1); //shows "I am so happy." in the output window.
trace(happy5); //shows "I am so happy." in the output window.

How would I do this in php?

Dynamically Create A Table's Columns
What I'd like to do, is take the selected rows from my database, generate columns dynamically to reflect the "size" column, and then dump the data respectively into the table that is generated. Here's what I've got so far:
Using this database:

What I've done is given each row/column a designation by assigning a X,Y value (tag_no, size). I created an array that uses a key in the same X,Y format. I loop through the rows to dump the array value that corresponds to the key.

The data doens't display correctly if I there are multiple tag_no's that have the same sizes, with different quantities. Code:

Dynamically Create Table Rows As Needed
I have a form with a table. Each table row has a ID= "some number". I have 4 rows and might need to create more. how can i do this in php? To go along with this, When I hit the submit buton, I then need all the table row data saved to a db i have. I can insert 1 line with out a issue. I also made sure the table row name="" fields are unique. ex. Code:

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?

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.

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

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

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
from a MySQL DB i want to get a multidimensional array that i can loop

echo 'field is '.$row['Field'] . ' type is ' . $row['Type'];
if (ereg('enum.(.*).', $row['Field'], $match))
{
$opts = explode(',', $match[1]);
foreach ($opts as $item)
{$finalResult[] = substr($item, 1, strlen($item)-2);}
}

$array=array ($row['Field'] =>$finalResult[]);

}
gives Fatal error :Cannot use [] for reading in .......

array[$x][0]=$row['Field']
array[$x][1]=$finalResult[]

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
I have a multidimensional array where each sub-array contains just two
entries, which indicates a relationship between those two entries. for
example the first sub-array:
[0] => Array

[0] => 30
[1] => 31
)
This states that value 30 is related to 31. I would like to search...

How To Print A Multidimensional Associative Array?

How To Call A Column Instead Of Row In A Multidimensional Array
I have a 2-d array. I want to pass columns from the 2-d array to a file that will graph the columns.

Let's say its called my2darray

I can pass a row with something like my2darray[4]

But I can't pass a specific column with my2darray[][4]

Any help with the syntax or a link to the solution would be helpful. Do I have to use a loop to call a whole column?

Retrieve Multidimensional Array From Mysql?
I am developing a site to sell dvds. Each dvd can have multiple actors, I have created a select query that returns the film information and if there is more than 1 actor associated, more than 1 row is returned. I have tried to use the mysqli_fetch_array function to retrieve all the rows but this only seems to retrieve the first row.

I assumed it would create a multidimensional array but I cannot find a second row. I have tried such things as $row[0][actor_name], $row[1][actor_name] but this does not work.

Array Sort: Multidimensional Arrays?
I'm horrible at arrays. And I'm now using a script that has a lot of neat predefined functions and things that I adore and would never have time to come up with myself.

I'm facing a problem with sorting an array in it though. Can't figure out where to really go in and... determine how to get the info displayed in correct order.

the $tpl->assign_block_vars basically creates a loop out of variables to output using a html template. Now... I want all this sorted by the variable called 'CURRENT'. Can't do ORDER BY in the sql statements since it's nested within a other sql statement call etc. Any help would be apprecciated. Here's the code: .....

PHP Stops Processing On Multidimensional Associative Array
When using a multidimensional associative array to cross-reference data
in a second, single-dimensional array, PHP stops processing data after
a few iterations. Memory usage according to the task manager doesn't
seem to spike and CPU usage only gets as high as 11 to 13 percent. A
sample script is provided below, any help or alternative solutions are
welcome. (By the way, the script below works fine on Linux with the
same version of Apache and PHP. Possibly a PHP configuration issue?)
