Following the code copies of a little function I've wrote that actually works with
multidimensional arrays.
It also resets the array indexes.
<?php
if ( !function_exists( "arrayUnique" ) ){
function arrayUnique ( $rArray ){
$rReturn = array ();
while ( list( $key, $val ) = each ( $rArray ) ){
if ( !in_array( $val, $rReturn ) )
array_push( $rReturn, $val );
}
return $rReturn;
}
}
?>
