[!--quoteo(post=371289:date=May 4 2006, 11:28 AM:name=ober)--][div class=\'quotetop\']QUOTE(ober @ May 4 2006, 11:28 AM) [snapback]371289[/snapback][/div][div class=\'quotemain\'][!--quotec--] $this is a keyword within a class that refers to the classes global variables. $this->variable_name = "x"; will set the class's variable equal to x. The .= is an append. It will add whatever is past the equals sign to the current string instead of replacing it. [/quote] Thank you, that is what i needed to know! that make a lot more sence when i read through other code.
