Quick and painless Tiny URL generator

Given you don't want to have to take the time to setup a URL shortening system, here is a short script to use tinyurl.com's system.

<?php
function tinyurl_gen($url)  {  
  if(filter_var($url,FILTER_SANITIZE_URL)){
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL,'http://tinyurl.com/api-create.php?url='.$url);  
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);  
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5);  
    $data = curl_exec($ch);  
    curl_close($ch);  
  return $data;   
  }
  else{
    return false;
  }
}
