try regular expressions:

<?php

$doc_name = "another-nice-image.gif";
$doc_type_image = ereg("(gif$|jpg$|psd$)",$doc_name);

if ($doc_type_image == 1){
?>
the document is an image...
<?php
}

?>

the above example looks IF $doc_name ENDS with gif OR jpg OR psd and
writes the result in $doc_type_image.

if you want to learn more about regular expressions have a look at [
www.devshed.com ] they have a tutorial about regular expressions on
their site.

cheers,
andreas
