1、当执行B:cat()时,属于“非转发调用”,存储的是B 2、当执行到cat方法时,get_class输出当前类名 A,get_called_class,则输出“非转发调用”存储的B类名 demo2、 classA{staticpublicfunctioncat(){var_dump(get_class());var_dump(get_called_class());}}classBextendsA{publicstaticfunctiondog(){A::...
get_class (): 获取当前调用方法的类名; get_called_class():获取静态绑定后的类名; abstract class dbObject { const TABLE_NAME='undefined'; public static function GetAll() { $c = get_called_class(); return "SELECT * FROM `".$c::TABLE_NAME."`"; } } class dbPerson extends dbObject ...

get_class()用于实例调用,加入参数($this)可解决子类继承调用的问题,而get_called_class()则是用于静态方法调用。 需要注意的是:get_called_class()需要 PHP>=5.3.0 才支持,官方手册:http://php.net/manual/en/function.get-called-class.php,对于 PHP5.3.0以下的版本,有人给出了如下实现方...
php CLASS、get_class()与get_called_class()的区别 获取当前的类名,get_class与上面一样,都是获取当前的类名get_called_class获取当前主调类的类名 当涉及到继承时,在方法中使用类名。直接贴图了 image.png
