Array Sorting issue--php

[vssp]

Hai friends
I need to sort the array values.

Array value is
Array ( [160x600] => Array ( [0] => 21 [1] => 1 [2] => 0 [3] => 0 ) [300x250] => Array ( [0] => 32 [1] => 2 [2] => 0 [3] => 0 ) )


First I am using ksort to sort the array values.Now I neet to sort [0] => 21 and [0] => 32


How to sort Array in array ? Please send any suggestion

Thanks

[0] =>21 and [0] 32 are not arrays, so I assume you mean the sub-arrays. This sample sort the 300x250 sub-array.
[php]<?php
$arr=Array ('160x600' => Array ( 0 => 21, 1 => 1, 2 => 0, 3 => 0 ) ,
'300x250' => Array ( 0 => 32, 1 => 2, 2 => 0, 3 => 0 ) );
sort($arr['300x250']);
echo '<pre>'; print_r($arr);
?>[/php]
Result:

Array
(
    [160x600] => Array
        (
            [0] => 21
            [1] => 1
            [2] => 0
            [3] => 0
        )
    [300x250] => Array
        (
            [0] => 0
            [1] => 0
            [2] => 2
            [3] => 32
        )
)
