PHP has a large number of functions which accommodate this. Primarily it sounds like you want to physically check that a page exists remotely by attempting to access it and dealing with the results.
If you are able to, the best solution would be to use the cURL extension which allows PHP to be a full-fledged browser of sorts - it knows about HTTP and can deal with the various issues that come up when checking a page exists (404 errors, etc). You would initiate a request to the provided URL and see if you get content or an error in reply.
The cURL documentation is at: http://www.php.net/manual/en/book.curl.php
If you cannot install extensions, it's OK - most PHP functions that accept filenames can also take URLs! For example, you could attempt loading the page using: $page = file_get_contents($URL). However, there's less definition as to what happens if the remote end provides a large 404 response, etc - so cURL would be preferrable.
Please keep in mind that any URL provided may be malicious: check with the parse_url() function to restrict to HTTP/HTTPS and keep "URLs" like file:///etc/passwd from succeeding!
