When dealing with php array we sometimes needs sorting functionality.if we want to sort an array based on a key in php here is the function which helps you to do so.
<?php function subval_sort($array,$subkey,$sr) { foreach($array as $k=>$v) { $b[$k] = strtolower($v[$subkey]); } if($sr=='asc'){ asort($b);} else{arsort($b);} foreach($b as $key=>$val) { $c[] = $a[$key]; } return $c; } ?>
here,
$array is the array to be sorted.
$subkey is the key.
$sr is the order asc or desc.
