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；
有例为证：
class Foo{ public function test(){ var_dump(get_class()); } public function test2(){ var_dump(get_called_class()); } public static function test3(){ var_dump(get_class()); } public static function test4(){ var_dump(get_called_class()); } } class B extends Foo{ } $B=new B(); $B->test(); $B->test2(); Foo::test3(); Foo::test4(); B::test3(); B::test4();
输出结果：
string ‘Foo‘ (length=3) string ‘B‘ (length=1) string ‘Foo‘ (length=3) string ‘Foo‘ (length=3) string ‘Foo‘ (length=3) string ‘B‘ (length=1)
