discuz声明类难道还有另类的方法吗

C::creatapp();class core{	private static $_tables;	private static $_imports;	private static $_app;	private static $_memory;	public static function app() {		return self::$_app;	}	public static function creatapp() {		if(!is_object(self::$_app)) {			self::$_app = discuz_application::instance();		}		return self::$_app;	}

回复讨论(解决方案)

你没看到 class C extends core {} 这样的代码吗？

/source/class/class_core.php
文件最下面不是有句这个么...
class C extends core {}
