Removing duplicate entries in an array

[gizmo]

I have an array containing a list of image filenames and I wish to remove any duplicate entries. I am sure I have seen an array function that will do this, but searching here and also the PHP Manual, but have found nothing.

array_unique (http://www.php.net/array_unique)()

Thanks for the help, NogDog, I knew I had seen it somewhere.
