升级到 5.4 时 PHP 失败

Question

我正在使用 PHP 和 MySQL 在装有 PHP 5.2 的 2003 机器上提取程序、类(class)等。我正在将我的网站转移到一个新的 2008 框与 PHP 5.4(因为对数据库的注入(inject)攻击)。我的数据仍然从我的新服务器提取到我的站点(程序、类(class)等)。

问题是我有一个用于登录但不会加载的页面(HTTP 500 错误)。我已经追溯到踢出的代码部分，并相信它是 session_start()。我知道在 5.3 中它发生了变化，现在如果启动失败将返回 false 而不是之前的 true。

我尝试逐行回显每个变量加载的内容，因为我可以将它与两个版本进行比较。我试过从一开始就开始 session 。在我的代码之前结束它等等。看起来很简单，但我还没有让它工作。

这是我的页面“login-inc-header.php”的开头:

<?php
    if(!isset($session_started)) $session_started = session_start();
    // avoids duplicate pstings
    header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
    header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
    ini_set("display_errors", "1");
    if(!isset($requires)) $requires = "User";
    include_once("includes/handleLogin.php"); 
    include_once("../includes_app/db_settings.php");
?>

如果我删除此 block ，该页面将在没有我的登录框的情况下加载。 Pages 在 5.2 版本中完美运行。想法？

我的数据库设置:

<?php
    //$site_root = "/var/www/html/";
    $site_root = "C:\\Inetpub\\wwwroot\\";  //changed 12-13-13 for new server

我注意到它引用了 PEAR，它不像旧版本那样默认安装。这可能是问题所在吗？

您已将此设置为您的站点根目录

$site_root = "C:\\Inetpub\\wwwroot\\";

尝试放置

$site_root = "http://yourhost/folder_name/"
