Hi, Joe Stump schrieb:
I only asked because I saw XML_Parser was calling XML_Parser::__construct() from function XML_Parser(). I though $this->__construct() would be safer. A bug possibly?
Imagine this class: MyParser extends XML_Parser { 
     function MyParser()
     {
       $this->__construct();
     }

     function __construct()
     {
       ....
       parent::XML_Parser();
     }
} If you create a new instance and XML_Parser would be using $this->__construct(), it would call MyParser::__construct() instead of XML_Parser::__construct(). That's why XML_Parser is specifying the class name. Otherwise inheritance is no longer possible or will totally break scripts.
