Ereg?

[onlinehoster]

Hi,

I think this can be done with an ereg, i tried working out how to do it ( reading through php.net ) but no luck.

What i need to do is to filter out any characters which are not alphanumeric in a string.

Example:

The user submits the username: elite%%mo34(

So $user = elite%%mo34(

What i want to do is then change $user to elitemo34

If anyone can do a bit of code to do that, it would be great.

Thanks

Hope this helps.

function clear($dirty_text){
    $new_string = eregi_replace("[^_a-z0-9 ]","",$dirty_text);
	$pat=" ";
	$repl="";
	$newtext=str_replace($pat,$repl,$new_string);
	return $newtext;
	}
