still fairly new to working with regular expressions.
What the best/easiest way to check whether a variable contains a

It can be done; but, it's simpler to simply to make an if() with
(strlen($password) > 5) && (strlen($password) < max) &&
pre_match("%[a-z]+%i"%, $password) && preg_match("%\d+%", $password)
Some mistakes there:
1) You want to assign strlen to a variable before the if, since you're
calling it twice in the if. I'm not certain how fast strlen is, but it's
usually a bad idea to repeat useless function calls like that.
2) Isn't your second function call supposed to be preg_match, and not
pre_match?

You are correct on both counts. Getting the strlen() first will save about .01usec.
