ereg function help

[Anon]

Hi. Could anyone explain me how the *,[^],., and some other characters work within the ereg function?

I just stand looking at the examples, but i don't seem to be able to guess it. Could you at least point me some place where i could learn something about it?

Thanks in advance.

Hallo.

Forexample the following line is used to control the validity of Email Address. The Email contains only a-z, A-Z, @, -(minus), _(underscore), .(punkt).

if(!eregi("^{[a-zA-Z0-9_-]+@[a-zA-Z0-9-_]+.[a-zA-Z0-9-.]+$",} $email))
