Inserting a print_r into your test script tells you the problem, as does a closer look at http://www.php.net/ksort . You're assuming ksort()'s return value is the sorted array. It is not. Try something more along the lines of: $testarray=array( "[three]" => 3, "[two]" => 2, "[one]" => 1, ); ksort($testarray); print_r($testarray); -- Paul Chvostek <paul@it.ca> Operations / Abuse / Whatever it.canada, hosting and development http://www.it.ca/
