one-liner to remove any duplicates from an array (indexes are a little messed up, but if array is
huge and u only care about removing duplicates, works like a charm)
<?
$ar=array("abba","boomer","boston","abba","bozer");
print_r(array_flip(array_flip($ar)));
?>
output:
Array
(
[3] => abba
[1] => boomer
[2] => boston
[4] => bozer
)
