PHP 会话变量随文件包含而变化

这个问题基于之前的我问过的问题，但编辑变得混乱，因为我没有确定问题可能来自哪里。（如果这个问题需要关闭，请告知）

我在开发环境+ Apache 2上使用PHP 5.3.3进行开发（我的代码在那里工作）生产服务器有 PHP 5.2.6 和相同的服务器（相同的代码在这里不起作用）

感谢 Melsi 在另一个问题上的帮助，我设法将问题范围缩小到几行代码。

问题是：在包含文件中，我启动一个会话并检查变量。根据该会话变量，我包含一个语言文件。

结构如下：

-index.php
INCLUDE
    -menus.php
    -lang_fr.php
    -lang_en.php

文件如下：

INDEX.PHP

<?php
    //SET LANGUAGE
    if (isset($_GET['lang']) && $_GET['lang'] == 'fr') {
        $_SESSION['lang'] = 'fr';
    }
    else if (isset($_GET['lang']) && $_GET['lang'] == 'en') {
        $_SESSION['lang'] = 'en';
    }
    else {
        $_SESSION['lang'] = 'en';
    }
    include_once 'include/menus.php';
?>

<html>
<head>
    <title>building...</title>
</head>
<body>

    <?php
            echo($links);
    ?>

<br><br>

print_r($_SESSION);

<br><br>

    <?php
            print_r($_SESSION);
    ?>

</body>
</html>

MENUS.PHP

<?php
    session_start();
    if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'en') {
        include_once('lang_en.php');
    }
    else if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'fr') {
        include_once('lang_fr.php');
    }
    else {
        $_SESSION['lang'] = 'fr';
        include_once('lang_fr.php');
    }
    $links = <<<EOT
    <a href="/index.php?lang=en">English</a>&nbsp;&nbsp;
    <a href="/index.php?lang=fr">French</a>
EOT;

?>

LAN_EN 和 FR.PHP

<?php

$lang['test'] = "Test";

?>

这在我的本地服务器上工作并在我单击链接时显示正确的会话变量。

在生产服务器上，我得到：

-第一次加载：Array ( [lang] => fr )（默认，正确）

-单击英文链接：Array ( [lang] => fr ) Tn )

- 单击法语链接：Array ( [lang] => Tr )

如果我将语言文件 'Test' 更改为 'Pest'，上面的结果是 ' Pn' 和'Pr'

我想知道代码或配置生产服务器是否有问题（根据他们的支持，没有任何问题），如果有，可能是什么问题。

注意：当我删除menus.php中的包含时，问题消失了

This question is based on a previous question I asked but is getting messy with edits as I was not sure where the problem could come from. (Please advise if this question needs to be closed)

I develop with PHP 5.3.3 on development environment + Apache 2 (my code works there)
The production server has PHP 5.2.6 and the same server (same code doesn't work here)

Thanks to Melsi on the other question I managed to narrow down the problem to a few lines of code.

The problem is: In an include file I start a session and check for a variable.
Depending on that session variable I include a language file.

The structure is like this:

-index.php
INCLUDE
    -menus.php
    -lang_fr.php
    -lang_en.php

The files are as follows:

INDEX.PHP

<?php
    //SET LANGUAGE
    if (isset($_GET['lang']) && $_GET['lang'] == 'fr') {
        $_SESSION['lang'] = 'fr';
    }
    else if (isset($_GET['lang']) && $_GET['lang'] == 'en') {
        $_SESSION['lang'] = 'en';
    }
    else {
        $_SESSION['lang'] = 'en';
    }
    include_once 'include/menus.php';
?>

<html>
<head>
    <title>building...</title>
</head>
<body>

    <?php
            echo($links);
    ?>

<br><br>

print_r($_SESSION);

<br><br>

    <?php
            print_r($_SESSION);
    ?>

</body>
</html>

MENUS.PHP

<?php
    session_start();
    if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'en') {
        include_once('lang_en.php');
    }
    else if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'fr') {
        include_once('lang_fr.php');
    }
    else {
        $_SESSION['lang'] = 'fr';
        include_once('lang_fr.php');
    }
    $links = <<<EOT
    <a href="/index.php?lang=en">English</a>  
    <a href="/index.php?lang=fr">French</a>
EOT;

?>

LAN_EN and FR.PHP

<?php

$lang['test'] = "Test";

?>

This on my local server works and displays the correct session variables when I click on the links.

On the production server I get:

-First load: Array ( [lang] => fr ) (default, correct)

-Click on English link: Array ( [lang] => Tn )

-Click on the French link: Array ( [lang] => Tr )

If I change in the language file 'Test' to 'Pest', the results above are 'Pn' and 'Pr'

I would like to know if there's something wrong with the code or with the configuration production server (according to their support there is nothing wrong) and if so what could be the problem.

Note: The problem disappears when I remove the includes in menus.php

代码中的问题是您在 Index.php 中设置设置变量并在 Menu.php 文件中启动会话。请将其更改为：

Index.php

<?php
    ob_start();
    session_start();

    //SET LANGUAGE
    if (isset($_GET['lang']) && $_GET['lang'] == 'fr') {
        $_SESSION['lang'] = 'fr';
    }
    else if (isset($_GET['lang']) && $_GET['lang'] == 'en') {
        $_SESSION['lang'] = 'en';
    }
    else {
        $_SESSION['lang'] = 'en';
    }
    include_once 'include/menus.php';
?>

<html>
<head>
    <title>building...</title>
</head>
<body>

    <?php
            echo($links);
    ?>

<br><br>

print_r($_SESSION);

<br><br>

    <?php
            print_r($_SESSION);
    ?>

</body>
</html>

MENUS.PHP

<?php
    if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'en') {
        include_once('lang_en.php');
    }
    else if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'fr') {
        include_once('lang_fr.php');
    }
    else {
        $_SESSION['lang'] = 'fr';
        include_once('lang_fr.php');
    }
    $links = <<<EOT
    <a href="/index.php?lang=en">English</a>  
    <a href="/index.php?lang=fr">French</a>
EOT;

?>

我认为这可以解决您的问题

The problem in your code is that you as setting the Setting variables and in Index.php but Starting the Session in Menu.php file. Kindly change thing to:

Index.php

<?php
    ob_start();
    session_start();

    //SET LANGUAGE
    if (isset($_GET['lang']) && $_GET['lang'] == 'fr') {
        $_SESSION['lang'] = 'fr';
    }
    else if (isset($_GET['lang']) && $_GET['lang'] == 'en') {
        $_SESSION['lang'] = 'en';
    }
    else {
        $_SESSION['lang'] = 'en';
    }
    include_once 'include/menus.php';
?>

<html>
<head>
    <title>building...</title>
</head>
<body>

    <?php
            echo($links);
    ?>

<br><br>

print_r($_SESSION);

<br><br>

    <?php
            print_r($_SESSION);
    ?>

</body>
</html>

MENUS.PHP

<?php
    if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'en') {
        include_once('lang_en.php');
    }
    else if(isset($_SESSION['lang']) && $_SESSION['lang'] == 'fr') {
        include_once('lang_fr.php');
    }
    else {
        $_SESSION['lang'] = 'fr';
        include_once('lang_fr.php');
    }
    $links = <<<EOT
    <a href="/index.php?lang=en">English</a>  
    <a href="/index.php?lang=fr">French</a>
EOT;

?>

I Think this would resolve your problem

如果您仔细查看我的answear在上一个问题中提到的第一件事（以粗体写出）正是这样：

也许会话是从包含的文件开始的，这不应该发生！

Vineet 是正确的，我将扩展他的正确答案再多一点！

当您将文件 child.php 包含到father.php 中时，您必须将 child.php 中找到的代码视为father.php 的一部分您在father.php 脚本（如index.php）中要做的第一件事之一是一个会话开始。您不要在包含的脚本中启动会话，因为这可能会产生一些冲突，因为其他会话可能已经启动。

如果您有很多文件（如果由于没有单个入口点而直接包含或直接执行其中一些文件，则情况更糟）那么管理所有这些文件有多容易？！

你这样说：
