php模組化供前端ajax呼叫的實作 ajax php post jquery ajax php ajax分

背景：沒有使用php框架
由於臨時需求，需要ajax呼叫php中的方法，簡單的寫了一個php文件，文件定義了兩個方法，如何用ajax分別呼叫同一個php文件不同的方法。
以下是abc.php文件，我定義的兩個方法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，這個文件是調用其他特定的功能類的控制器，起到樞紐作用，主要是透過反射來實作

<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呼叫時，使用如下寫法實作只呼叫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>

如果需要傳參數，可以這麼寫來呼叫：

<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); }); });

以上就介紹了php模組化供前端ajax呼叫的實現，包括了ajax,php方面的內容，希望對PHP教程有興趣的朋友有幫助。
