session.upload_progress start session automatically

Question

PHP session.upload_progress is a good library to track your upload progress, however when you send a file to server, session.upload_progress start php session automatically, that's does not play fine with Zend Framework causing an exception when you call:

$Session = new Zend_Session_Namespace ( 'zend_session' , true );

Exception:

session has already been started by session.auto-start or session_start()

With my session.auto_start set to "Off", I put on the top of the page the code below:

// no one command is executed before this
echo "<pre>";
print_r ($_SESSION );
exit;

• Just calling page without upload: PHP says that $_SESSION is not set
• Posting a form with a file: PHP shows the entire $_SESSION var even without calling session_start()

my Session section configuration:

Session Support     enabled
Registered save handlers    files user memcache memcached redis
Registered serializer handlers  php_serialize php php_binary wddx igbinary

I does not have an session_start() on my code, I just let ZendFramework do it by run:

Zend_Registry::set( "session" , new Zend_Session_Namespace ( 'zend_session' , true ) ) ;

Answer 1

in Zend_Session() : 456 it test:

if (!self::$_unitTestEnabled && defined('SID')) ...

SID is defined but $_SESSION is empty. but the problem is that this is a Zend Framework class, you can comment it if you want, but it's not recomended to change framework files
