This is handy for accessing private methods but remember that things are normally private for a reason! Unit Testing is one (debatable) use case for this.
Example:
<?php
class Foo {
private function myPrivateMethod() {
return 7;
}
}
$method = new ReflectionMethod('Foo', 'myPrivateMethod');
$method->setAccessible(true);
echo $method->invoke(new Foo);
// echos "7"
?>
This works nicely with PHPUnit: http://php.net/manual/en/reflectionmethod.setaccessible.php
ReflectionMethod::setAccessible
(PHP 5 >= 5.3.2, PHP 7, PHP 8)
ReflectionMethod::setAccessible — 设置方法是否可访问
说明
通过 ReflectionMethod::invoke() 方法启用对 protected 或 private 方法的调用。
注意: 自 PHP 8.1.0 起，调用此方法无效；默认情况下，所有方法都可调用。
参数
-
accessible -
可以访问设置
true，否则设置false。
返回值
没有返回值。
示例
示例 #1 简单类定义
<?php
class MyClass
{
private function foo()
{
return 'bar';
}
}
$method = new ReflectionMethod("MyClass", "foo");
$method->setAccessible(true);
$obj = new MyClass();
echo $method->invoke($obj);
echo $obj->foo();
?>以上示例的输出类似于：
bar Fatal error: Uncaught Error: Call to private method MyClass::foo() from global scope in /in/qdaZS:16
