Chunking and Assi=ociative array into smaller arrays.

OK I have an multidimensional array $arrLists:-

AStatus
            For Sale
                        ID          125
                        Other       99
            Hold Sale
                        ID          56
                        Other       12
            Not for Sale
                        ID          22
                        Other       32
Base
            Canvas
                        ID          326
                        Other       99
            Cloth
                        ID          17
                        Other       9

I want to split it into two smaller arrays $arrAStatus:-
For Sale
            ID          125
            Other       99
Hold Sale
            ID          56
            Other       12
Not for Sale
            ID          22
            Other       32

Open in new window


and $arrBase:-

Canvas
            ID          326
            Other       99
Cloth
            ID          17
            Other       9

Open in new window


How do I achieve this?

Try this

<?php
    $a = Array('AStatus' => Array('For Sale' => Array('ID' => 125, 'Other' => 99),
                                    'Hold Sale' => Array('ID' => 56, 'Other' => 12),
                                    'Not for Sale' => Array('ID' => 22, 'Other' => 32)
                                   ),
                'Base' => Array('Canvas' => Array('ID' => 326, 'Other' => 99),
                                 'Cloth' => Array('ID' => 17, 'Other' => 9)
                                )
               );
?>

    <pre>
    <?php print_r($a); ?>
    </pre>
    
<?php
    foreach($a as $key => $val){
        
        $vn = "arr".$key;
        $nvn = $$vn = $val;
        
        echo"<pre>";
        print_r($nvn);
        echo"</pre>";
    }
?>

$arrAStatus = $arrLists['AStatus'];
$arrBase = $arrLists['Base'];

Sorry I can see now that I have been less that specific. Indeed what you suggest would work but I want to loop through $arrLists and create each array automatically based on the key.

Thanks that's brilliant.

I'm not familiar with the syntax:-

$nvn = $$vn = $val;

Can you enlightne me?

Lukasz ChmielewskiCommented:
Sure,

// this below makes the array name based on the key,
// so there are two arrays arrAStatus, arrBase
// vn - variable name
$vn = "arr".$key;

// nvn - new variable name
// adding $ to $ makes a variables variable, because the $vn is the string
// for example "arrBase", so adding an extra $ will produce a variable named $arrBase
// and assign the $val to it, which in this case is the array below
$nvn = $$vn = $val;

Hope it's clear

in other words:

$newVariable = $("arrAStatus"/"arrBase") = the array for the proper key
