Valid url check form validation in codeigniter

Here is code I have for a url validation function in CI, and this is the callback function 

function valid_url($facebook)
    {
        $pattern = "/^((ht|f)tp(s?)\:\/\/|~/|/)?([w]{2}([\w\-]+\.)+([\w]{2,5}))(:[\d]{1,5})?/";
        if (!preg_match($pattern, $facebook))
        {
            return FALSE;
        }

        return TRUE;
    }

I'm getting this error 

Message: preg_match() [function.preg-match]: Unknown modifier '|'

Try this

        function validate_url($url) {
        $data = trim($url);
        $data = stripslashes($url);
        $data = htmlspecialchars($url);
        return $url;


     // check address syntax is valid or not(this regular expression also allows dashes in the URL)
        if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$url)) {
        return FALSE;
        } else {
    return TRUE;
    }
     } 
  $check =  validate_url($url);
