PHP Function Compilation

[Muffins]

Hi, I just had an idea for a compilation of functions that will help with some developments.

I hope this thread will help some people.
Please post in the format I do.

What's it for?

Filtering text(meant for POST and GET request's) to make sure there is no malicious code etc...

Usage:
filter(text to filter)

Actual function:

    function filter($var)
    {
        return mysql_real_escape_string(stripslashes(htmlspecialchars($var)));
    }

Yes, I stole this from some cms and stuff.
