PHP modularization for front-end ajax call implementation ajax php post jquery ajax php ajax points

Background: No php framework is used
Due to temporary needs, I need ajax to call methods in php. I simply wrote a php file. The file defines two methods. How to use ajax to call different methods of the same php file.
The following is the abc.php file. The two methods I defined, a method and b method

classabc
    {functiona(){echo something;
        }
        functionb($args){echo something;
            }
        }
    }
?>

The following is Controller.php. This file is a controller that calls other specific functional classes and plays a pivotal role, mainly through reflection. When implementing

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($_REQUEST));                              
                }    
            }  
        } 
        catch (Exception$exc) {    
            echo$exc->getTraceAsString();  
        }
    }
?>

using ajax, use the following writing method to only call the a method in abc.php:

$.ajax({
         type:"POST",
         url: 'Controller.php?action=abc/a',    
         dataType: 'json',
         success: function(data) {         }
      });

If you need to pass parameters, you can call it like this:

$.ajax({
         type:"POST",
         url: 'Controller.php',   
         data:{
            action=abc/b,
            参数1: 123,
            参数2: 456}
         dataType: 'json',
         success: function(data) {

         }
      });

').addClass('pre-numbering' ).hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces the implementation of PHP modularization for front-end ajax calls, including the content of ajax and PHP. I hope it will be helpful to friends who are interested in PHP tutorials.
