I had a problem with array_unique and multidimensional arrays ... Maybe there's a better way to do this, but this will work for any dimensional arrays.
<?php
function arrayUnique($myArray)
{
if(!is_array($myArray))
return $myArray;
foreach ($myArray as &$myvalue){
$myvalue=serialize($myvalue);
}
$myArray=array_unique($myArray);
foreach ($myArray as &$myvalue){
$myvalue=unserialize($myvalue);
}
return $myArray;
}
?>
