How do you check if a given URL matches at least a sitename?
I have:
$url_to_match = 'http://sub.somesite.com/'; I want to say "MATCH found" for input starting with http://sub.somesite.com only.
Any help would be very much appreciated.

Use PHP's parse_url():
$url = 'http://sub.somesite.com/'; if ('sub.somesite.com' === parse_url($url, PHP_URL_HOST)) { // we have a match } 
use parse_url
example:
function match_url($base,$input) { $base_host = parse_url($base,PHP_URL_HOST); $input_host = parse_url($input,PHP_URL_HOST); if( $base_host === $input_host ) { return true; } else { return false; } } $base_url = 'http://sub.somesite.com'; $input_url = 'http://sub.somesite.com//bla/bla'; echo (match_url($base_url,$input_url)) ? "URL matched" : "URL mismatched";

I think you need to tell us what you are doing since this request makes no design sense.
However, to answer the question.
if(strpos($url_to_match, 'http://sub.anothersite.com/bla') !== FALSE) print 'bad string';

This is wrong usage of strpos() (syntax error), but yes, based on the question, you need to use strpos(), read here lt.php.net/strpos

I have clarified my question. I am afraid doing checking the opposite is not what I meant. Thanks
