Remote Server Header Checking

[ukgimp]

I am trying to find out how to check remote server headers, with a preference based on 200 response.

but it only works for 200 type, If the site does not resolve it just stays blank. Ideally I would put a switch statement in to allow for mutliple types.

Is there a problem with my IF statement or something else more sinister.

Cheers

$fp = fsockopen ($host, 80, $errno, $errstr, 20);

$host = $parse['host'];

fclose ($fp);
echo htmlentities($headers);


if(ereg("200 OK", $headers, $regs))
{
print "200 = OK";
}
else
{
print "not 200";
}
}
$url = "http://www.google.co.uk";
remote_file_exists($url);
?>

Using Curl is probably a better way of doing this.
