I think it's better to make it more readable by splitting it into lines.

$requestUrl = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '/';
$requestUrl = Strings::replace($requestUrl, '#^\w+://[^/]+#i');

The pattern could be optimized by removing pointless case-insensitive flag and avoiding any possible backtracking

$requestUrl = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '/';
$requestUrl = Strings::replace($requestUrl, '#^\w++://[^/]++#');

With removed backtracking, we may probably replace Strings::replace with faster preg_replace

$requestUrl = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '/';
$requestUrl = preg_replace('#^\w++://[^/]++#', '', $requestUrl);

OK, you're right. I have modified it. Thanks.

Is this actually RFC compliant? What if I send mismatching Host header or use different protocol than used in here? Shouldn't we strip it only if it is a match and throw exception otherwise?

See how Symfony handles this. They replace it only if it matches current schema and host. But I haven't seen any specification which would define how this should actually be handled.
