Functions-Online.com is a handy web tool for testing preg_match in your PHP scripts. Just drop in your regex, a test string, and pick your PHP version to see what matches. It’s great for debugging tricky patterns, experimenting with new ones, or just brushing up on how regex works in PHP. No need to spin up a local server—it all runs right in your browser. If you write PHP and deal with regular expressions now and then, this tool makes the whole process quicker and way less frustrating. Definitely one to keep in your bookmarks.
