Check the array_unique() function
http://www.php.net/manual/function.array-unique.php
]
You could also sort the array using any of the sorting functions and then
something like:
reset( $array );
while( list( $pos, $val ) = each( $array )) {
if( $val == $last )
unset( $array[ $pos ] );
$last = $val;
}
