usort() PHP Function Issue with PHP 5.3

Most of you may be faced this issue, usort() behaves differently in PHP 5.1 & 5.3 versions.

E.g

<?php
class myClass {
  public static function mySortMethod($object1, $object2)
  {
     if ($object1->order == $object2->order) 
    {
         return 0;
    }
    return ($object1->order < $object2->order) ? -1 : 1;
  }
}

usort($arr, 'myClass: mySortMethod');

?>

This would be working fine till PHP 5.1, but in latest version means PHP 5.3 it doesn’t sort properly.

Solution:

There is a small change required while calling usort() and it will work fine.
use –

usort($arr, array(‘myClass’,’mySortMethod’));
This will solve issue of usort() sorting method with PHp 5.3 version.

Try it!!!
