PHP experts how would you do this?

[Azathoth]

In perl say you did this:

$username =~ tr/[0-9a-zA-Z_\-]//csd;
( This would strip all but alphanumeric chars and _ and - chars )

What would be the equivelant in PHP? I can't seem to find one

eregi("^[A-Za-z0-9_-]+$",$foo) is what i use.

so just change that to eregi_replace

$username = eregi_replace("^[A-Za-z0-9_-]+$","",$username)

i didn't like relying on \w or \W (and i think i had some problems with it)

Excellent thanks.. I'll give it a shot.
