问题描述
应如何编写条件php以使其生效?
我已经编辑了购物车的主要index.php，以便根据当前url包含适当的配置文件，尽管编写方式无效:
how should a conditional php include be written for it to take effect?
I have edited my cart's main index.php so as to include the appropriate config file based on the current url, though the way it is written doesn't work:
(下面是整个文件，我的版本在//mine START和//mine END之间)
(whole file below, my edition is between //mine START and //mine END)
<?php
session_start();
@$cart = $_SESSION["cart"];

foreach ($_GET as $get_key => $get_value) {
if ((preg_match("/\//", $get_value)) || (preg_match("/[\\\]/", $get_value)) || (preg_match("/:/", $get_value))) {
eval("unset(\${$get_key});");
die("A hacking attempt has been detected. For security reasons, we're blocking any code execution.");
}

编辑:由于@SgtAJ的评论，下面的版本(仍然有些古怪?)效果很好
thanks to @SgtAJ 's comment, the below (still wonky?) edition works fine
$url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
if (strpos($_SERVER['REQUEST_URI'], '?fr') !== false){include 'configFr.php';}
else {include 'config.php';}
推荐答案
您可以这样做:
if (isset($_GET['fr']))
{ include 'configFr.php'; }
else if (isset($_GET['en']))
{ include 'config.php'; }
else
{ include 'config.php'; }
这将检查?fr和?en，并且将包括一个文件，无论是否同时存在一个或两个文件.
This will check for ?fr and for ?en, and will include a single file no matter if one, both, or none of those is present.
