PHP :: Filtering The Elements Of A Multi-dimensional Array

Finding Elements Of An Array In Another Multi-dimensional Array
So I have 2 arrays:
one contains userids. It may look like:
user_id[0] =12,
user_id[1] =30,
user_id[2] =43

The other is a multi-dimensional array with fields like:
user_info [0] = Array
(
[user_id] =13
[user_flag] =1
[url] =http://www.example.com?index,0
)
user_info[1] =Array
{
Array
(
[user_id] =120
[user_flag] =1
[address] =1234 Main St, Anytown, USA
[url] =http://www.yahoo.com
)
user_info[2] =Array
{
Array
(
[user_id] =130
[user_flag] =1
[address] =134 Main St, Anytown, USA
[url] =http://www.google.com
)

Processing Data From Multiple Multi-line Textareas Into A Multi-dimensional Array
I know that this sounds like something overly complex - because it is.
However, if I can keep the user interface the way it is, my users will
be ultra happy! That is the goal...

In general, this is an inventory receiving piece of an overall larger
web-based ERP system.

What I have is a form in which I have a dynamic number of multline
textareas for inputting (possibly barcode scanning in) many serial
numbers per line item recieved.

For example:
lineitem01 = widget01; qtyReceived = 2;
lineitem02 = widget02; qtyReceived = 3;
lineitem03 = widget03; qtyReceived = 10;

This would display a form that will generate 3 textarea elements (1
per lineitem received). Inside each textarea element will be input the
serial numbers for each of the widgets received per lineitem. i.e. 2
serial numbers will be entered for widget01; 3 for widget02; and 10
for widget03;

So, what I am trying to do is pass this data over, possibly as a multi-
dimensional array to another form ( or possibly $_SERVER['PHP_SELF'] ) to update a MySQL database to store the widget/serial numbers.

Multi Sorting Multi Dimensional Array?
I have been using usort to sort my multi dimensional arrays ...

function cmp($a, $b){
if($a[0] == $b[0]){
return 0;
}
return ($a[0] < $b[0]) ? -1 : 1;
}
usort($searchResults, 'cmp');

Which works fine, but I need to sort by one element in the array, then
another, preserving the previous sort.

lets say the array is as follows:

array[0] = array[0] = foo
[1] = 2
[1] = array[0] = foo
[1] = 0
[2] = array[0] = bar
[1] = 1
[3] = array[0] = bar
[1] = 0
[4] = array[0] = foo
[1] = 1
[5] = array[0] = bar
[1] = 2

Initially, I sort the array in to groups based on array[?][0] using
usort as above so the output is :

foo, 2
foo, 0
foo, 1
bar, 1
bar, 2
bar, 0

Next though, I would like to sort this output by number (array[?][1])
in the groups so that the output is :

foo, 0
foo, 1
foo, 2
bar, 0
bar, 1
bar, 2

Is this possible? I am completely at a loss as to how to do this ...

Assigning A Multi-dimensional Array To & From A Session Variable Loses The Array
I have created a multidimensional array and then assigned that array to a session variable so that I can use it easily on another page. However, when I go to the array later, there's never anything in it. Code:

Multi-Dimensional Array
Let's say I have the following multidimensional array:

$foodtypes = array (
"Fruit" => array ("Apple", "Pear"),
"Vegetable" => array ("Lettuce", "Eggplant", "Pepper"),
"Meat" => array ("Beef", "Pork"));

Assuming that $food = 'Eggplant', How do I find what foodtype it belongs to? I know the following works, but I know there must be a better way to do this, like using array_search or array_keys. I can't get anything other the following to work though. Code:

Multi Dimensional Array
I want to go create a table with a textfield where the user can
enter an amount for a certain dynamically created article coming from
the database.

Later, I want to calculate the whole price and so on.
It works nicely to create my multi dimensional array,
however, it does not work to save the values coming from the form to
calculate the price.
What's wrong???

<form name="shop" method="post" action="index.php">
$articleTable = array();

while ($row = mysql_fetch_array($result)) {
$articleNr= $row["articleNr"];
$name= $row["name"];
$picName= $row["picName"];
$price = $row["price"];
$amount="";

$articleRow = array(
"articleNr" => $articleNr,
"name" => $name,
"picName" => $bildName,
"price " => $price ,
"amount" => $amount
);

array_push($articleTable , $articleRow );

}

foreach($articleTable as $article) {
?>
<input type="text" name="article[amount]" size="2" maxlength="2"
value="<? $article[amount] ?>"></td>
}

<?
}
?>
</form>

Building Multi Dimensional Array
I am trying to build a multi dimensional array from an unsorted array. I have an array made up of the lines in a text file, each line is a comma seperated set of fields. The first two fields are the lines id and it's parents id; eg Line ID, Parent ID, Data

1, 1 , one
2, 2, two
3, 3, three
4, 1, four
5, 4, five
6, 1, six
7, 2, seven

I am trying to build a multi dimensional array so that the final array would look like;

-- one
---- four
------ five
---- six
-- two
---- seven

Sessions And A Multi-dimensional Array
I'm writing a shopping cart w/ Sessions and a multi-dimensional array. I am only storing product id and qty (for right now, but decided on the multi-dimensional array for expansion purposes - storing customer instructions, etc.) I have come up with two paths, but can't decide which is better.

1. storing info based on product id:
...[cart][$prod_id] = array("qty" => $qty)

This, of course would allow for easy product checks: if ([cart][$prod_id]) {...}, but unless I store the $prod_id in the prod_id array as well, I'd be forced to use foreach(array_expression as $key => $value) when displaying the cart (as I also want the product id displayed next to the product name)

2. storing info based on item number:
...[cart][] = array("id" => $prod_id, "qty" => $qty)

This makes for more code when checking if the product is already in the cart (multiple foreach statements), but should allow the cart to be displayed more easily and logical.

Sorting Multi-dimensional Array
I am having trouble getting the sort function for arrays to work correctly on my multi-dimensional array.

array[0][]=Ƈ'
array[1][]='bob'
array[2][]='age'

array[0][]=Ƌ'
array[1][]='bill'
array[2][]='age'

I then do sort($array[0]) But only array[0][] gets sorted, the names do not follow. Does anyone see any error on my part or have a clue for me to follow to solve this?

Printing From A Multi-dimensional Array
I have to create a multidimensional array that data for a bank will be stored in then from that array I will print it. My boss said to first program it like i am recieving the array. Then later he will have me create the array.

Multi-dimensional Array Sorting
I need some help sorting an array, same in structure as:

Array
(
[assoc1] => Array
(
[key1] => value
[key2] => value
[key3] => value
)

[assoc2] => Array
(
[key1] => value
[key2] => value
[key3] => value
))

What I want to do is sort the array by the value in say the key2 "column". Depending on input, the value to sort by may be key3 or some other key.

I've looked at array_multisort(), but I'm not sure how I can specify what exact column I want to sort by, without affecting the rest.

Multi-dimensional Array Not Working Correctly???
I know this is going to be something totally stupid that I just can't see. I have a two dimensional arrray. The first index is a 0 based incremented int, and the other index is either an 'l' or a 'w'. Look what's happening:

Parsing All Multi-Dimensional Array Combinations
I am trying to build a dynamic table structure with multi-dimensional arrays. The first dimension is being pulled from the databse and can be refferred to as an attribute. The second dimension is also created on the fly by db, and can be reffered to as variations. I have tried using array_walk as well as using a recursive function that allows me to step through each of the various array combinations.

For example I may have 2 attributes; Color & Size. Color has 3 variations (Red, Green, Blue). Size has 4 varitions (Small, Medium Large, X-Large). Basically I am trying to build something like this:

Color Size
Red Small
Red Medium
Red Large
Red X-Large
Green Small
Green Medium
Green Large
Green X-Large
Blue Small
Blue Medium
Blue Large
Blue X-Large

The biggest problem with this, however, is that it needs to be dynamic enough that an attribute (like sleeve length: Short sleeve - Lon sleeve, etc...) can be added without changing the code.

Sorting An Associative Multi-Dimensional Array

Adding A Entry Into A Multi-dimensional Array
I make an SQL call to a DB and gather some info. In the following case, I have 2 elements in the array (HERO_ID #1 and #2) I then want to add a third element to to the array, but I just cant seem to grasp the concept. I always seemed to have trouble grasping the concept of arrays in programming classes for some reason. Code:

How To Declare A Global Multi Dimensional Array?
i cant figure this one out... this code declares a 1d array global. however i need a multid array to be global.... global $list_U001;

since i need a maximum of only 99 arrays...i could decklare those like that and construct the variable from counter ...but i dont know how to construct a "dynamic variable"....

global $list_U001;
global $list_U002;
global $list_U003;
etc...

for(i++)

$list_U00.'$i'.[]

Selecting 1 Field From A Multi-Dimensional Array
I want to know how do I select just 1 field from a Multi-Dimensional Array.
I know how to select all the fields, by using the following format:

<?php
foreach($fields as $key => $val){
echo $val;
}

But how can I do a similar thing, but to just select 1 specific field, not all of them?

Turn Array Into Multi-dimensional Array?
How can I take an existing array and turn it into a multi-dimensional array? I want to get a single row out of a MySQL table and have it in an array, but have along side the values the true field (column) length for each of the fields from the table. Here's my stab at it:

$userDetails = mysql_fetch_array($resultID);
$i = 0;
while ($i < mysql_num_fields($resultID))
{
$userDetails[$i][2] = mysql_field_len($resultID, $i);
$i++;
}

And I guess the follow up question (if this is indeed possible) is will this work with a multi-row return from the DB also?

Encoding / Decoding Multi Dimensional Session Array
Can you encode and decode multi-dimensional arrays? I think encoding them works just fine using session_encode(), however, session_decode is only capable of decoding the single dimensional arrays stored in the encoded string...

Making Mysql Result Into Multi-dimensional Array
My php problem is I want to make the result of 3 tables linked through foreign keys into a 3-dimensional array that reflects their relationship without repetition and without having to call the database more three times.

I know I'm doing a couple of things wrong, one thing for instance is initializing a variable at the end of the loop to remember the previous value s that it does not repeat itself, surely there must be a more elegant way to go about this, but I'm lost and I've been stuck on this all day. Code:

Pushing Data Into A Multi-dimensional Array From Mysql Results
First, A result array I'd want to get could look like this:

$chart['chart_data'] = array (
array ( "Region A", 10,12,11,15,20,22,21,25,31,32,),
);

The first is "Region A" and the rest is just int's that I'd pull from the db, so to set it I'd do this:

$chart [ 'chart_data' ][ 0 ][ 0 ] = "Region A";

But the problem is when I want to insert the data in the while loop (like the 10,12,11,15...), I've tried array_push but it's not working, maybe it doesn't work with multi-dimensional arrays? Anyways, here.'s what I tried, the following inside the "while" to loop the mysql results with mysql_fetch_assoc:

while($r=mysql_fetch_assoc($res)) {

$chart [ 'chart_data' ][ 0 ][ 0 ] = array_push($chart['chart_data'][0][0], $r['wght']);
// the above line is where I have problems ^^
}

What I want is on each loop to insert the fetched data inside the array so that it gives what I gave first at the top, but what I've written above doesn't work, it gives me a warning saying "first argument must be an array" which seems to be one, but anyway, anybody know how to do this?

"Array To String Conversion" Error When Constructing A Multi-dimensional Array
I'm a bit stumped as I am getting a "Notice: Array to String
Conversion" error when trying to do something that on the surface
should be a very simple task - create an array, and write a set of
values to them based on data submitted from POST Fields.

Code below:

$_SESSION["increment"] = array();
$x = 0 // Counter - This will be
incremented

$_SESSION["increment"][$x] = array("increment_bond" =>
$_POST["increment_bond"],
"increment_amount" = $_POST["increment_amount"],
"increment_comm_date1" = $_POST["increment_comm_date1"],
"increment_comm_date2" =$_POST["increment_comm_date2"],
"increment_comm_date3" = $_POST["increment_comm_date3"]);

It keeps throwing out that error, and does not write any of the POST
Values to the array (the POST values are definitely getting sent, so
that is not the problem).

If I dump out the value of $_SESSION["increment"], I get "1A" ?!?

I'm sure that there is a pretty simple mistake lurking somewhere - I
just can't seem to figure it out.

Multi-dimensional In Php3
Hi,
I was using php4 on my test area and setup a 3d array like below....

<input type="text" name="col[<?echo $i1; ?>][<?echo $i; ?>]" value="<?
/* if begin is yes then get input value from db */
if (($begin=="yes")| |($new_setnum == $setnum))
{
echo $row_payele[$item2];
}
/* else print current input box value */
else
{
echo trim($col[$i1][$i]);
}?>" maxlength="8" size="4">

then i reference the value in the same way...
$col[$i2][$i] etc..

This all worked fine on my own machine which is using php4. but when I go to the live server which is using php3 the variable is not picked up. Even if I try using $col[1][1] it doesn't work. Does anyone know why and a work around to it in php3??? Thanks in advance.

Multi-Dimensional Arrays
okay, i need to make a arrray that holds an array of 2 different id numbers, $catagory_id and $subcatagor_id are both variables inside a loop that take on a different number each loop. I want to put those number inside an array, each one being it's on array, but I need those numbers to be inside another array that I can call to find another array that will be inside that same array: sounds confusing, but basically, I have a table with ID's each id is assigned a catagory and and a sub catagory, each id is unique but there could be multiple id's under the same sub_cat and cat. So, i need the array to be set up so that I could call all id's that have a certain cat and subcat number:

echo ("$idnumber[$cat_id][$subcat_id]");

something like that, can anyone help?

Now how do I sort the $austin array by team points after
they have been populated?

Sorting Multi Dimensional Arrays.
I am writing a meta search engine script and each results gets a score based on a number of factors. What I'm trying to do is sort the results with the highest score first, ready for output.

So the Array looks like this

}
[1]=> array(4) {
[Title]=> "My site2"
[Description]=> "whatever"
[Url]=> "url.com"
[Score]=> "223"
}
}

Obviuosly there are more than 2 results in real life, but is there anyway to sort the array so My Site2, with a score of 223 will appear first?

League Table - Multi-dimensional Arrays
I am seting up a league table for a friend and i have found i need to use multi-dimensional arrays. I have little experience of these in PHP and this is what's wrong in my code i believe.

Array Sorting Blues....2 Dimensional Array
I have a 2 dimensional array where one col contains a Unix style date and the other contains a filename. I read through a directory to get this info. I can load the array and print it out just fine, but I can't seem to sort it using any of the sort functions! I want to reverse sort them, since they are news stories that I want to display in the correct order by date. When I try to sort I get a "Warning: Cannot compare arrays or objects" message. I have the feeling it's something stupid on my part but can't find any good examples anywhere.

Anyone have an idea about this?

P.S. I know a database would solve this but sadly it's not an option for me right now...

Add Array Elements?

Creating An Array Of Two Elements From Another Array
I’m trying to create an array that contains a department name and a associated colour code, by filtering from a SQL result. I’ve written a simple script, but to be honest I’m now stumped how to create such an array. PHP Code:

Remove Array Elements With The Given Value From Array
If I have an array, $myarray, with the elements values like (1, 2, 3, 6, 8, 10).

I need a function applies to this $myarray to get rid of the element with certain value

such as

array_function_i_am_looking_for($myarray, 3) will return $myarray with the values (1, 2, 6, 8, 10).

I checked out the array function manual. The closest one is array_filter. And I just need to write a function to compare the value for array_filter.

Two Dimensional Array Problem
I want to put the contents of a csv file into a 2 dimensional array so that
I can access any element in a $table[x][y] manner and have come up with the
following code:

$complete = file("source.csv");
$row=0;
foreach ($complete as $value) {
$data = explode(",", $value);
$table[$row] = $data;
$row++;
}
echo "$table[6][4]";

However the echo statement returns "Array[4]" instead of the 4th element in
the 6th row.

Any suggestions on what I ought to be doing please to make $table a proper 2
