Php 在include链接中添加$\u GET变量

如何在我的include链接中添加$\u GET变量的内容

<?php $variable = $_GET['variable']; ?>

此处放置了我的变量：

<?php
    include 'includes/link_(variable placed here).php';

?>

只需使用：

---

仅供参考，这是一个很好的例子。您应该在使用该值之前对其进行清理和验证。

您只需将其作为字符串使用即可：

include 'includes/link_'.$variable;

---

在基于用户输入的代码中尝试使用include时要小心。麻烦，沸腾，冒泡

它可以像任何其他字符串一样连接：

include 'includes/link_' .$variable;

但是，在includes中使用用户输入时，您必须验证和验证数据，以确保您不会让自己面临错误。

这可能有助于：

<?php

/* This example assumes that www.example.com is configured to parse .php
* files and not .txt files. Also, 'Works' here means that the variables
* $foo and $bar are available within the included file. */

// Won't work; file.txt wasn't handled by www.example.com as PHP
include 'http://www.example.com/file.txt?foo=1&bar=2';

// Won't work; looks for a file named 'file.php?foo=1&bar=2' on the
// local filesystem.
include 'file.php?foo=1&bar=2';

// Works.
include 'http://www.example.com/file.php?foo=1&bar=2';

$foo = 1;
$bar = 2;
include 'file.txt';  // Works.
include 'file.php';  // Works.

?>

为什么存在安全风险？？有人可以将任意文件路径作为变量传递，这可能会导致脚本下载恶意代码。

// Won't work; file.txt wasn't handled by www.example.com as PHP
include 'http://www.example.com/file.txt?foo=1&bar=2';

// Won't work; looks for a file named 'file.php?foo=1&bar=2' on the

include 'file.php?foo=1&bar=2';

// Works.
include 'http://www.example.com/file.php?foo=1&bar=2';

$foo = 1;
$bar = 2;
include 'file.txt';  // Works.
include 'file.php';  // Works.
