PHP反射之类的反射

Posted 2020-08-15

最近在琢磨如何用php实现站点的插件功能，需要用到反射，于是现学了一下，笔记如下：

class Person
{
    public $name = ‘Lily‘;
    public $gender = ‘male‘;
    public $age = 20;

    public function eat()
    {
        echo ‘Lily is eating!‘;
    }

    public function run()
    {
        echo ‘Lily is running!‘;
    }
}
$ref = new ReflectionClass(Person::class);
$methods = $ref->getMethods();
foreach ($methods as $method) {
    $method->invoke(new $method->class, $method->name);
}

1、反射类

2、获取类的方法

3、遍历并执行方法

输出结果：

Lily is eating!

Lily is running!
