RE: [PHP] Which is faster?

> I'm wondering which is faster, eregi('[A-Z]',$variable); or > ereg('A-Za-z',$variable);? Well, you're not even matching the same thing, for one... And, second, why not read this page, www.php.net/microtime so you can do your own testing in the future? They run about the same in my tests, assuming you're looking for [a-zA-Z] in the second example. Even preg_match ran about the same speed. I'd recommend you do your own testing in your actual program though. Generally, preg_* is faster than ereg* but it depends on what you're actually doing. ---John Holmes...
