file_get_contents() what to do if url not respond?

[Imaulle]

Hello, is this ok to do? or should I add in some type of fail safe in case for some reason the server is down etc? If so, how?

 

        public function check_update()
{
	$query  = $this->db->where('setting_name', 'version')->get('settings')->row();
	$latest = file_get_contents('http://www.mydomain.com/version.txt') )

	if ( version_compare($query->value, $latest, '<') )

		return true;

	else

		return false;

}
