Re: Re: [PHP-WIN] a interesting direction about Class in PHP.

How to use "parent::" to call a parent class? I always get a "undefined class name 'parent'" error. why? I know there are many undocumented things in PHP since PHP is a current developing language. I am very interested to know about the detail of those. Could you please give me some clue to get it? Websites,Ebooks or something else would be great appreciated. ―――――――――――――――――――――――――――――――――――――― >BTW, there's even an undocumented way to call a parent class >without knowing its name: "parent::". > > >At 13:50 19.12. 2000, Adam Bear wrote the following: >-------------------------------------------------------------- >>This (static class method calls through classname::methodname) >>has been in PHP 4 for quite some time.
