Note Submitter: webmaster at zeroweb dot org ---- Needed a quick, fairly uncluttered way of sorting an array of objects by a certain object attribute, so here's what I came up with. Uses one global array and usort(). Also accepts an optional sort direction argument (CSORT_ASC = sort ascending, CSORT_DESC = sort descending). Use it like this: (assuming $myarray is your array, "index" is the attribute you want to sort by, and you want to sort in descending order) csort($myarray, "index", CSORT_DESC); Hope this is of use to someone. Probably a better way to pull this off, but this works alright. <?php define("CSORT_ASC", 1); define("CSORT_DESC", -1); function csort_cmp(&$a, &$b) { global $csort_cmp; if ($a->$csort_cmp['key'] > $b->$csort_cmp['key']) return $csort_cmp['direction']; if ($a->$csort_cmp['key'] < $b->$csort_cmp['key']) return -1 * $csort_cmp['direction']; return 0; } function csort(&$a, $k, $sort_direction=CSORT_ASC) { global $csort_cmp; $csort_cmp = array( 'key' => $k, 'direction' => $sort_direction ); usort($a, "csort_cmp"); unset($csort_cmp); } ?>
