True, array_unique does preserve keys, but if you are incrementing in a loop, then it will stop once
the key values break numerical order. If you don't care about preserving keys, a life-saver
(originally a headache) for me was...
<?php
$new_array = array_keys(array_flip($old_array));
?>
i used this little snip-it after results from preg_match_all() as a way to remove duplicates from an
array and then re-organize the numerical keys ;)
*Only works on arrays with numerical keys.
