条件付きのPHPはURLに基​​づいていますか？

Question

条件付きのPHPをどのように記述して有効にする必要がありますか？
現在のURLに基​​づいて、適切な設定ファイルを含むように、それが書かれている方法では動作しませんが、私は、私のカートのメインのindex.phpを編集した：

（ ？以下のファイル全体は、私の版は私が）//

<?php

    $cart    = md5(uniqid(rand()));

} 
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."); 
    } 
}

EDIT鉱山ENDを開始して、//の間にある：@SgtAJさんのコメントにおかげで、以下の（まだグラグラが）版が正常に動作します

$url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; 
if (strpos($_SERVER['REQUEST_URI'], '?fr') !== false){include 'configFr.php';} 
else {include 'config.php';} 

Answer 1

あなたはそれをこのように行うことができます：？？

if (isset($_GET['fr'])) 
    { include 'configFr.php'; } 
else if (isset($_GET['en'])) 
    { include 'config.php'; } 
else 
    { include 'config.php'; } 

これはFRと専用のためをチェックすると、1つが単一のファイルに関係なく含まれます、両方、またはそれらのどれも存在しません。
