[PHP] Checking for characters in string

[Richard Black]

Hi,

I'm writing a page which will allow user's to register for an online service. They 
register a username and password.

I want the password to contain at least one lowercase letter, at least one upper case 
letter, and at least one digit. So 

passW0rd would be valid, but password would not.

Whats the most compact way to do this? substr? ereg?

Richy

I think regular expressions is the best way because working with strings
looks like this:

if ($strtolower($pass)!=$pass)  ($strtoupper($pass)!=$pass) {
  echo OK!;
} else {
  echo WRONG!;
}

but using reg expr it's even more shorter
