利用PHP實現短網址功能

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

// USAGE


$longurl= "http://www.google.com/search?q=symfony project&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:tr:official&client=firefox-a";
$shorturl = shorturl($longurl);
echo "$shorturl";

?>
