A very simple way to sort an array of associative arrays by some value is to use usort. I needed to sort an array of 20 data structures by their 'distance' value: Array ( [0] => Array ( [blahblah] => blahblah [distance] => 6 ) [1] => Array ( you get the idea.... Here's the code: -------------------- usort($results, "distributor_compare"); /** * usort callback */ function distributor_compare($a, $b) { $adist = intval($a['distance']); $bdist = intval($b['distance']); if ($adist == $bdist) { return 0; } return ($adist < $bdist) ? -1 : 1; } -------------------- ---- Server IP: 203.220.0.234 Probable Submitter: 203.206.235.237 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.array-multisort.php Edit -- http://master.php.net/note/edit/63516 Del: integrated -- http://master.php.net/note/delete/63516/integrated Del: useless -- http://master.php.net/note/delete/63516/useless Del: bad code -- http://master.php.net/note/delete/63516/bad+code Del: spam -- http://master.php.net/note/delete/63516/spam Del: non-english -- http://master.php.net/note/delete/63516/non-english Del: in docs -- http://master.php.net/note/delete/63516/in+docs Del: other reasons-- http://master.php.net/note/delete/63516 Reject -- http://master.php.net/note/reject/63516 Search -- http://master.php.net/manage/user-notes.php
