RegExp in Strings

[IWeb]

Hello,

I want to ban e.g. certain email adresses.
In the ban list the entries look like:
<regexp>@.com
abc<regexp>@.com
...

<regexp> stands for a regular expresion.

Now, if someone tries to register with an email adress like [e-mail] a message is returned, that the email adress is banned.

How can I run/parse such regular expressions in strings?

Thanks,

[dalecosp]

[man]ereg[/man]
[man]eregi[/man]
[man]ereg_replace[/man]

PHP also does PCRE (Perl-Compatible Regular Expressions):

[man]preg[/man]
[man]preg_match[/man]

etc., etc.

I know these functions 😉, but I thought to complicated.
I already found an easy solution.
