Difference between uasort() and usort(), the missing example ... <?php $arr = array ( 10 => array('id' => 'dix', 'aa' => '1010'), 100 => array('id' => 'cent', 'aa' => '100100'), 2 => array('id' => 'deux', 'aa' => '22'), 7 => array('id' => 'sept', 'aa' => '77')); // id sorting function so ($a, $b) { return (strcmp ($a['id'],$b['id'])); } ?> *** uasort($arr, 'so') output: <?php Array ( [100] => Array ( [id] => cent [aa] => 100100 ) [2] => Array ( [id] => deux [aa] => 22 ) [10] => Array ( [id] => dix [aa] => 1010 ) [7] => Array ( [id] => sept [aa] => 77 ))?> *** usort($arr, 'so') output: <?php Array ( [0] => Array ( [id] => cent [aa] => 100100 ) [1] => Array ( [id] => deux [aa] => 22 ) [2] => Array ( [id] => dix [aa] => 1010 ) [3] => Array ( [id] => sept [aa] => 77 ))?> ---- Server IP: 61.195.146.164 Probable Submitter: 218.219.209.195 ---- Manual Page -- http://www.php.net/manual/en/function.uasort.php Edit -- https://master.php.net/note/edit/83701 Del: integrated -- https://master.php.net/note/delete/83701/integrated Del: useless -- https://master.php.net/note/delete/83701/useless Del: bad code -- https://master.php.net/note/delete/83701/bad+code Del: spam -- https://master.php.net/note/delete/83701/spam Del: non-english -- https://master.php.net/note/delete/83701/non-english Del: in docs -- https://master.php.net/note/delete/83701/in+docs Del: other reasons-- https://master.php.net/note/delete/83701 Reject -- https://master.php.net/note/reject/83701 Search -- https://master.php.net/manage/user-notes.php
