Instead of taking illegal characters out for the user, wouldn't it be better
to not process the submission and send an error message back to them... like
"Please enter a username with only letters and numbers. No spaces or special
characters allowed".
Then you could just use ereg.
if ( ereg("^[[:alnum:]]+$" , $_POST['username'] ) {
// process submission
} else {
// don't process submission... have user enter another username
}
You might want to set a limit on the length though...
... ereg("^[[:alnum:]]{3,10}$", ...
