To sort a list of objects either ascending (a) or descending (d) using key use the function below
for comparison.
<?php
function property_sort($oa, $ob) {
global $sort_key;
global $sort_dir;
$a = strtolower($oa->$sort_key);
$b = strtolower($ob->$sort_key);
if ($a == $b) {
return 0;
} else if (($a > $b && $sort_dir == "a") || ($a < $b && $sort_dir
== "d")) {
return 1;
} else {
return -1;
}
}
