String Expression for apha numeric password

**visualAd** · Oct 31st, 2002, 05:43 PM

I need a string expression to verify an alpha numeric password. This is what
i've come up with , however it does not work:

PHP Code:


elseif ( (!ereg ("^[a-zA-Z]+$", $password)) || (!ereg ("^[0-9]+$",

$password)))

can anybody help? Thanks in advance

try this

elseif ( (!ereg ("^[:ALPHA:]+$", $password)))

or

elseif ( (!ereg ("^[a-zA-Z0-9]+$", $password)))
