I kind of understand array sorting, but I am still lost... > > -Dan Joseph If you want to maintain key order, use uasort(); if, however, you want the array to be reindexed sequentially when you sort it, use usort(): http://www.php.net/manual/en/function.uasort.php http://www.php.net/manual/en/function.usort.php A short example (with the usual caveats about 'make sure you add error checking): <?php error_reporting(E_ALL); $data = array(array('loan_info' => 104, 'first_name' => 'jack', 'last_name' => 'mother'), array('loan_info' => 102, 'first_name' => 'jill', 'last_name' => 'brother'), array('loan_info' => 108, 'first_name' => 'jim', 'last_name' => 'the'), array('loan_info' => 107, 'first_name' => 'bob', 'last_name' => 'whole'), array('loan_info' => 105, 'first_name' => 'alice', 'last_name' => 'fam'), array('loan_info' => 103, 'first_name' => 'ellen', 'last_name' => 'damily')); function cmp($a, $b) { return strcmp($a['loan_info'], $b['loan_info']); } uasort($data, 'cmp'); print_r($data); ?> Hope this helps, Torben -- Torben Wilson <torben@php.net> +1.604.709.0506 http://www.thebuttlesschaps.com http://www.inflatableeye.com http://www.hybrid17.com http://www.themainonmain.com -----==== Boycott Starbucks! http://www.haidabuckscafe.com ====-----
