[SOLVED] grabbing duplicates in an array, similar to array_unique()?

[aebstract]

I know that 'array_unique' will give me an array taking out duplicates, is there any way I can create an array and ONLY display duplicates? Let's say I have an array with like 6000 items and 10 items are duplicates, I need to display just the 10 items.

Something like this:

 

<?php

$array = array(1,2,3,3,4,5,5);
$unique = array_unique($array);
$duplicates = array_diff_assoc($array,$unique);
print_r($duplicates);

?>

And if the duplicates appear more than twice in the array, just run another array_unique() on $duplicates.

 

Edit: How obvious is that.. LOL

For what I am doing it won't matter if they are there more than twice or not, just need to know which ones do have dupes. Thanks
