PHP list,
I have a large set of PHP scripts of my own design that outputs any
errors to text log files.
These scripts are deployed on a few different sites, at different
virtual hosting services. On one, I keep seeing this error in my log files:
Error Handler message: session_start() [<a
href='function.session-start'>function.session-start</a>]: The session
id contains illegal characters, valid characters are a-z, A-Z, 0-9 and
'-,' /home/domains/mydomainname.com/public_html/index.php 107
Before I show the content of index.php, I want to emphasize that no
other virtual host produces this error. My home testing environment
doesn't either. I have doubly ensured that the scripts are the same
across all environments. So there must be something in the interaction
of my scripts on that hosting service that is causing this error.
Here are the contents of index.php, trimmed of most comments for
brevity. Line 107 is where the last session_start() call is.
My question is why would this code trip an error on one server, but not all?
Thank you for any advice.
--- code ---
include_once '+site/Settings.php';
include_once 'Global.php';
set_error_handler(array('ErrorHandler','handleError'), E_ALL);
// initialize the output tree. This is the structure that receives all
the ouput and stores it in a tree form
// based on the HTML structure
HTML::initializeTree();
$userRequest = trim($_SERVER['REQUEST_URI'], "/");
if (Browser::supportsCookies())
{
session_start();
}
else
{
if (strlen($userRequest) != 0)
{
$sessionArray = Session::decodeSessionID($userRequest);
if (is_array($sessionArray))
{
session_id($sessionArray[0]);
$userRequest = $sessionArray[1];
}
else
{
$userRequest = $sessionArray;
}
}
session_start();
}
