Yes, I can understand that but they are still difficult :p
And my book only talks about the other ones (those that work with ereg_replace :()

Shame, I notice a lot of them leave out PCRE.

Hopefully you'll find that link of use. ;)

Well by answer was the best for the original question, only to remove the spaces. If you have the choice, a str_replace is much faster. Dean however extended to original question nicely with the removal of some more special characters (although with some limitations that could also be done with str_trplace..

BEcause with a str_replace you can only search for a list of chracters. With regular expressions, you can also deny any character that is not in a list.

Dean C,

I noticed you are the only one in this thread with a space between first and last name, such as my user name.

So do I have to log out as David Copeland to use this forum's chat?? Or can the webmaster here modify the code to allow anyone with a space to use the live chat?

No, once you go into the chat and get the error just type:

Quote:

/nick NICKNAME

Replace NICKNAME with any other nickname that you want, and that doesn't produce an error. My username isn't allowed either thanks to the period, but I use Danny on the irc.

Mine also isn't allowed because of the space - I use ChrisM with no space :)

PHP Code:


		
			
// bad characters

$cleanchr = preg_replace("/[^ \\\\{}\^`\[\]\|\-\w]/", "", $vbulletin->userinfo['username']);



// leading numbers and dashes

$cleannum = ereg_replace("^[0-9\-]*[0-9\-]", "", $cleanchr);



// convert spaces to underscores

$nick = ereg_replace(" ", "_", $cleannum);
