Sorting Arrays In PHP

there are two ways to sort elements of array. If you want a simple default ascending order sorting with non-object array elements, then you can go for “sort” function. You just pass the array as parameter and it will sort the array and returns true if succeed.

$simple_array = array("dbc","bcd,"abc"); if(sort($simple_array)){ print_r($simpl_array); } If you want to define your own logic for sort condition and/or you are using objects as element of array, go for “usort” function. Example: 01 02 03 04 05 06 07 08 09 10 11 12 13 $elements = array();   $elements[0] = (object)NULL; $elements[0]->post_time = new DateTime();   $elements[1] = (object)NULL; $elements[1]->post_time = new DateTime();   usort($elements,"sort_function");   function sort_function( $a, $b ) {    return $b->post_time->diff($a->post_time)->invert; }
