Zend Application error if an unserialized object saved in $_SESSION since PHP 5.4

Question

My Project is a mixed project (Non-Zend & Zend) If i set in a Non-Zend environment something like

$myObject = new MyObject();
$_SESSION['foo'] = $myObject;

and calling later a zend controller (http://mydomain.foo/zendControllerName) i get

"An error occurred Application error"

It works only with serialized Objects in PHP 5.4 In PHP 5.2 it worked perfectly without serializing.

Answer 1

The Solution. Why does my PHP with Zend Framework go crazy about "session started" since update to 5.4 (after a session exists on filesystem)?

You can set it in application.ini:

resources.session.throw_startup_exceptions = false
