I am having the array of color attribute options...

I would like to sort the array based on 'store0' key...

I have used multisort and usort but its not working

[821] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 969
 [sort_order] => 513
 [store1] => Yellow
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => Yellow - KID
 [defaultswatch0] => 
 [swatch0] => 
 )

[822] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 207
 [sort_order] => 309
 [store1] => Yellow Beige - Chroma 1 ½
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => Yellow Beige - Chroma 1 ½
 [defaultswatch0] => 
 [swatch0] => 
 )

[823] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 857
 [sort_order] => 403
 [store1] => Yellow
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => Yellow-RAIN HAT BOB
 [defaultswatch0] => 
 [swatch0] => 
 )

[824] => Array
 (

 [intype] => radio
 [id] => 860
 [sort_order] => 406
 [store1] => Yellow
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => Yellow-WOMEN
 [defaultswatch0] => 
 [swatch0] => 
 )

[825] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 851
 [sort_order] => 400
 [store1] => Yellow
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => Yellow-WOMEN1
 [defaultswatch0] => 
 [swatch0] => 
 )

[826] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 29
 [sort_order] => 310
 [store1] => Zebra
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => Zebra
 [defaultswatch0] => 
 [swatch0] => 
 )

[827] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 1383
 [sort_order] => 830
 [store1] => abstract
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => abstract
 [defaultswatch0] => 
 [swatch0] => 
 )

[828] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 1382
 [sort_order] => 829
 [store1] => caol color
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => caol color
 [defaultswatch0] => 
 [swatch0] => 
 )

[829] => Array
 (
 [checked] => 
 [intype] => radio
 [id] => 1381
 [sort_order] => 829
 [store1] => cool color
 [defaultswatch1] => 
 [swatch1] => 
 [store0] => cool color
 [defaultswatch0] => 
 [swatch0] => 
 )

Here is the example, you can use this

function asc_sort (&$array, $key) 
 $sorter = array();
 $ret = array();
 reset($array);
 foreach ($array as $ii => $va) 
 $sorter[$ii] = $va[$key];
 
 asort($sorter);
 foreach ($sorter as $ii => $va) 
 $ret[$ii] = $array[$ii];
 
 $array = $ret;

asc_sort($a_array, "store0");

$arr = your array from above;

usort(
 $arr, 
 function($a, $b) 
 return strcmp($a['store0'], $b['store0']);
 
);

the usort function receives the first parameter by reference. So after the code above you can just iterate through $arr. It should be ordered by the store0 field.

$array = your_array;

function compareOrder($x, $y)

 return $x['store0'] - $y['store0'];

usort($array, 'compareOrder');
