I'm not sure I'd do the `trim()`. It might be useful if people are likely to paste passwords rather than typing them, but it might prevent enterprising users from putting a space on the end of their password.

thanksm can i just ask you how do you check for unwanted characters in the username, i only want letters, numbers, and underscores, and no spaces obviously

Was on my way out, saw your comment and did a quick search, this should help `if((ereg("^[a-zA-Z0-9_\-]+$", $your_variable_here)) { // value username }`

@staticsan .. i think you have a very valid point, my main reason of using it was to disallow people from just entering 6 spaces in there. something to think about for getaway :)

cheers! thank your a genius sebeeen

Lazy users are more likely to type `123456` or `password` as a bad password rather than six spaces. If you want to prevent bad passwords, you should do it properly: check for all the things that make a password "strong", assign points for each check and then require a minimum point score corresponding to most checks passing.
