<?php
function shortenurl($url){
	$length = strlen($url);
	if($length > 45){
		$length = $length - 30;
		$first = substr($url, 0, -$length);
		$last = substr($url, -15);
		$newurl = $first."[ ... ]".$last;
		return $newurl;
	}else{
		return $url;
	}
}

$longurl = "http://www.google.com/search?hl=en&client=firefox-a&channel=s&rls=org.mozilla%3Aen-US%3Aofficial&hs=BCR&q=metacafe&btnG=Search";
$shorturl = shortenurl($longurl);
echo"<a href=\"$longurl\">$shorturl</a>";
?>

$longurl is the long url that you want shortened.
$shorturl is calling the function to shorten the url down to 45 characters.
