Here's one I whipped up to allow you to sort an array of a specific class by a member or function:



<?php

// Sort a class by one of its members (even lowercase!!!)

function casort($arr, $var) {

   $tarr = array();

   $rarr = array();

   for($i = 0; $i < count($arr); $i++) {

      $element = $arr[$i];

      $tarr[] = strtolower($element->{$var});

   }



   reset($tarr);

   asort($tarr);

   $karr = array_keys($tarr);

   for($i = 0; $i < count($tarr); $i++) {

      $rarr[] = $arr[intval($karr[$i])];

   }



   return $rarr;

}

?>



It works very well. For example, I have a Room class with members title, isActive(), date, etc. I can sort an array by casort($rooms, "title") or casort($rooms, "isActive()") and it'll work.
