ajax+php controls all background function calls _php instances

A total of 3 to complete the PHP Ajax call logic, the following is the approximate structure

The first part: AJAX request: The main action This parameter, Logincontroller is the class name of PHP, login is logincontroller the function name in this class

$ (' #submit '). On (' click ', Function (e) {
    e.stoppropagation ();
    $.ajax ({
      URL: ".. /.. /controllers/controller.php ",
      data: {
        action:" Logincontroller/login ",
        Username:username,
        Password:password
      },
      dataType: "Text",
      type: ' POST ',
      timeout:10000,
      error:function () {
        alert ("Server timeout");
      },
      success:function (data) {
          alert (data);
  }});

Part II: controller.php, this file is to invoke other specific functional class controller, play a pivotal role, mainly through reflection to achieve

<?php

if (!empty ($_request[' action ')) {
  try {
    $action = explode ('/', $_request[' action ']);
    $class _name = $action [0];
    $method _name = $action [1];
    Require $class _name. '. php ';
    $class = new Reflectionclass ($class _name);
    if (class_exists ($class _name)) {
      if ($class->hasmethod ($method _name)) {
        $func = $class->getmethod ($ Method_name);
        $instance = $class->newinstance ();
        $func->invokeargs ($instance, Array ($_request));
        $result = $instance->getresult ();
        echo $result;}}}
  catch (Exception $exc) {
    echo $exc->gettraceasstring ();
  }

Part III: logincontroller.php, this file is a specific functional class

<?php
class Logincontroller {
  private $result;
  function Logincontroller () {
    //Initializing database connection parameters
  }
  function Login ($args) {
    //Specific login logic
  }
  function GetResult () {return
    $this->result;
  }
}
