php模块化供前端ajax调用的实现 ajax php post jquery ajax php ajax分

背景：没有使用php框架
由于临时需求，需要ajax调用php中的方法，简单的写了一个php文件，文件定义了两个方法，如何用ajax分别调用同一个php文件不同的方法。
以下是abc.php文件，我定义的两个方法a方法和b方法

<code><span><span><?php </span><span><span>class</span><span>abc</span>
    {</span><span><span>function</span><span>a</span><span>()</span>{</span><span>echo</span> something;
        }
        <span><span>function</span><span>b</span><span>(<span>$args</span>)</span>{</span><span>echo</span> something;
            }
        }
    }
<span>?></span></span></span></code>

以下是Controller.php，这个文件是调用其他具体的功能类的控制器，起到枢纽作用，主要是通过反射来实现

<code><span><span><?php </span><span>if</span> (!<span>empty</span>(<span>$_REQUEST</span>[<span>'action'</span>])) {  
        <span>try</span> {    
            <span>$action</span> = explode(<span>'/'</span>, <span>$_REQUEST</span>[<span>'action'</span>]);    
            <span>$class_name</span> = <span>$action</span>[<span>0</span>];    
            <span>$method_name</span> = <span>$action</span>[<span>1</span>];    
            <span>require</span><span>$class_name</span> . <span>'.php'</span>;    
            <span>$class</span> = <span>new</span> ReflectionClass(<span>$class_name</span>);    
            <span>if</span> (class_exists(<span>$class_name</span>)) {      
                <span>if</span> (<span>$class</span>->hasMethod(<span>$method_name</span>)) {        
                    <span>$func</span> = <span>$class</span>->getmethod(<span>$method_name</span>);        
                    <span>$instance</span> = <span>$class</span>->newInstance();        
                    <span>$func</span>->invokeArgs(<span>$instance</span>, <span>array</span>(<span>$_REQUEST</span>));                              
                }    
            }  
        } 
        <span>catch</span> (<span>Exception</span><span>$exc</span>) {    
            <span>echo</span><span>$exc</span>->getTraceAsString();  
        }
    }
<span>?></span></span></span></code>

使用ajax调用时，使用如下写法实现只调用abc.php中的a方法：

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

如果需要传参数，可以这么写来调用：

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

         }</span></span>
      });</code>

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

以上就介绍了php模块化供前端ajax调用的实现，包括了ajax,php方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
