OK, so here's my version that maintains index integrity:
<?php
function array_unique($array)
{
$out = array();
// loop through the inbound
foreach ($array as $key=>$value) {
// if the item isn't in the array
if (!in_array($value, $out)) {
// add it to the array
$out[$key] = $value;
}
}
return $out;
}
?>
