Ereg question

[bonehead]

Greetings,

I'd like to add somee error handling to a password field: if the
password is fewer than 5 characters or greater than 15 characters I'd
like to trap it. Special characters such as ^ and ~ will be allowed, but
spaces will not be allowed.

Can someone suggest and ereg expression that will help with this? Also,
does php have a length function similar to vb's len(mystring)?

Yup, regular expression is the perfect tool for this task. Try this:

echo preg_match('|^\\w{5,15}$|', $password) ? "Good" : "Bad";

Sure: $length = strlen($mystring);

Chung I must say you've been very very helpful. Sure hope you're getting
paid enough. And are you actually fluent in Polish?

I get paid well enough for someone who studies Polish :-)

The preg functions are usually faster than the ereg. And strlen() will give you
the string length.
