在< a>中调用PHP函数标签，锚标签 [英] Calling a PHP function within an <a > tag, anchor tag

问题描述

是否可以在锚标记中调用PHP函数？我有一个名为 logout（）;

的PHP函数现在我想要类似这样的东西。

 < a href =logout（）; >退出< / A> 
  

我知道Javascript有效，但使用PHP函数的最佳方法是什么？

解决方案

不; PHP是一种服务器端脚本语言，因此它无法像HTML那样访问HTML。 JavaScript可以做到这一点，因为它是客户端脚本语言。

因为PHP是一种服务器端语言，所以必须从浏览器（客户端）向服务器发送一条消息（以HTTP请求的形式）包括您的PHP函数 logout 。

您有几个选项...

选项1

按照超链接执行 logout（）函数的脚本...

HTML

 < a href =theLogOutScript .PHP>退出< / A> 
  

PHP

 <？php 
 // ... 
 logout（）; 
 // ... 
？> 
  

选项2

执行 logout（）函数的脚本...

HTML

 < form method =POSTaction =theLogOutScript.php> 
< input type =submitvalue =注销/> 
< / form> 
  

选项3

使用 XMLHttpRequest / AJAX请求与服务器进行通信。 （没有提供示例代码）

Is it possible to call a PHP function within an anchor tag. I have a PHP function called logout();

Now I want something similar to this.

<a href="logout();" >Logout</a>

I know with Javascript this works but what is the best approach using PHP function?

解决方案

No; PHP is a server side scripting language, so it is inaccessible to the HTML like this. JavaScript can do this, as it is a client-side scripting language.

Since PHP is a server side language, a message (in the form of an HTTP request) must be sent to the server from the browser (the client) for any PHP to be executed - including your PHP function logout.

You have a few options...

Option 1

Follow the hyperlink to a script which executes the logout() function...

HTML

<a href="theLogOutScript.php">Logout</a>

PHP

<?php
   // ...
   logout();
   // ...
?>

Option 2

Submit a form to a script which executes the logout() function...

HTML

<form method="POST" action="theLogOutScript.php">
    <input type="submit" value="Logout" />
</form>

Option 3

Use an XMLHttpRequest/AJAX request to communicate with the server. (no sample code provided)
