话不多说，一段代码实验下
<?php
class A{
public function a1(){
echo __FUNCTION__;
echo "\n";
echo __METHOD__;
echo "\n\n";
}
public static function a2(){
echo __FUNCTION__;
echo "\n";
echo __METHOD__;
echo "\n\n";
}
}
function a3(){
echo __FUNCTION__;
echo "\n";
echo __METHOD__;
echo "\n\n";
}
$a = new A();
$a->a1();
A::a2();
a3();输出如下
a1
A::a1
a2
A::a2
a3
a3结论
- 对于类成员函数，METHOD会带上类名，FUNCTION 没有类名
- 对于非类成员函数，没差别
