通过AJAX访问PHP类函数 [英] Accessing a PHP class function through AJAX

问题描述

有人知道我如何通过AJAX(使用jQuery)从PHP类直接访问函数.

Does anyone know how I can directly access a function from a PHP class through AJAX (using jQuery).

PHP:

class Blah
{
    function __construct()
    {
    }

    function doSomething(data)
    {
        echo "I am not an animal";
    }
}

jQuery:

$.ajax({
        url: myClass.php,
        data: Blah.doSomething(); "or" Blah->doSomething()  "or whatever"
    });

我知道这是一个粗糙的示例，我只是想说明一个观点，希望您能理解我的问题的要点.

I know this is a crude example, i'm just trying to illustrate a point, I hope you can get the gist of my question.

此刻，我正在按照以下方式进行操作:

At the moment i'm doing something along these lines:

$.ajax({
        url: myClass.php,
        data: data : { 'type':'doSomething' }
    });

||

if(POST['data']['type'] == 'doSomething')
{
     $this->doSomething();
}

我不喜欢它...

推荐答案

您需要创建该类的对象，然后调用所需的方法. 类声明不执行任何代码.

You need to create an object of that class and then invoke the methods you need. The class declaration doesn't not execute any code.

例如，您可以将其添加到类的下方:

For example, you can add this below the class:

class Blah { ... }
$b = new Blah();
$b->doSomething();

更新:

如果要调用POST中发送的方法，则可以使用函数call_user_function:

If you want to invoke the method sent in POST, you can use the function call_user_function:

$method_name = $_POST['method'];
$b->{$method_name}();
