PHP升级到5.4时失败

Question

I am using PHP with MySQL to pull programs, courses, etc. on 2003 box with PHP 5.2. I am transferring my site to a new 2008 box with PHP 5.4 (because of injection exploits on database). My data still pulls to my site (programs, courses etc) from my new server.

The issue is I have a page that is for login and will not load (HTTP 500 error). I have traced back to section of code that kicks out and believe it is the session_start() . I know in 5.3 it changed and will now return false if it fails to start instead of the previous true.

I've tried echoing out what loads line by line with each variable since I can compare it with the two versions. I've tried starting the session at the beginning. Ending it before my code, etc. It seems simple, but I haven't got it to work yet.

Here's the beginning of my page "login-inc-header.php":

<?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");
?>

If I remove this block, The page will load just without my login boxes. Pages works perfect in version 5.2. Ideas?

My db_settings:

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

I noticed that this referenced PEAR, which in not installed by default like older versions. Could this be the issue?

Answer 1

You have put this as your site root

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

Try putting

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