是否可以在PHP中声明静态和非静态方法? [英] Is it possible to declare a method static and nonstatic in PHP?

问题描述

我可以在对象中将方法声明为静态方法还是非静态方法，且其名称与调用静态方法的名称相同?

Can I declare a method in an object as both a static and non-static method with the same name that calls the static method?

我想创建一个类，该类具有一个静态方法"send"和一个调用该静态函数的非静态方法.例如:

I want to create a class that has a static method "send" and a non-static method that calls the static function. For example:

class test {
    private $text;
    public static function instance() {
        return new test();
    }

    public function setText($text) {
        $this->text = $text;
        return $this;
    }

    public function send() {
        self::send($this->text);
    }

    public static function send($text) {
        // send something
    }
}

我希望能够在这两个函数上调用该函数

I want to be able to call the function on these two was

test::send("Hello World!");

和

test::instance()->setText("Hello World")->send();

有可能吗?

推荐答案

您可以执行此操作，但这有点棘手.您必须通过重载来做到这一点: __call和__callStatic 魔术方法.

You can do this, but it's a bit tricky. You have to do it with overloading: the __call and __callStatic magic methods.

class test {
    private $text;
    public static function instance() {
        return new test();
    }

    public function setText($text) {
        $this->text = $text;
        return $this;
    }

    public function sendObject() {
        self::send($this->text);
    }

    public static function sendText($text) {
        // send something
    }

    public function __call($name, $arguments) {
        if ($name === 'send') {
            call_user_func(array($this, 'sendObject'));
        }
    }

    public static function __callStatic($name, $arguments) {
        if ($name === 'send') {
            call_user_func(array('test', 'sendText'), $arguments[0]);
        }
    }
}

这不是理想的解决方案，因为它会使您的代码难以理解，但是只要您的PHP> = 5.3，它就可以工作.

This isn't an ideal solution, as it makes your code harder to follow, but it will work, provided you have PHP >= 5.3.
