要在 PHP 中获取当前函数名称，代码如下 −
示例
<?php
class Base {
function display() {
echo "
Base class function declared final!";
var_dump(__FUNCTION__);
}
function demo() {
echo "
Base class function!";
}
}
class Derived extends Base {
function demo() {
echo "
Derived class function!";
}
}
$ob = new Base;
$ob->demo();
$ob->display();
$ob2 = new Derived;
$ob2->demo();
$ob2->display();
?>
输出
这将产生以下输出−
Base class function! Base class function declared final!string(7) "display" Derived class function! Base class function declared final!string(7) "display"
示例
现在让我们看另一个例子 −
<?php
class Base {
function display() {
echo "
Base class function declared final!";
var_dump(__FUNCTION__);
}
function demo() {
echo "
Base class function!";
var_dump(__METHOD__);
}
}
class Derived extends Base {
function demo() {
echo "
Derived class function!";
}
}
$ob = new Base;
$ob->demo();
$ob->display();
$ob2 = new Derived;
$ob2->demo();
$ob2->display();
?>
输出
这将产生以下输出−
Base class function!string(10) "Base::demo" Base class function declared final!string(7) "display" Derived class function! Base class function declared final!string(7) "display"
