Bug description: Object unserialization and session_start
I saw many reports about object serialization/unserialization and I want to
clarify what I understood.
Let's say you have the file 'foo.php' that defines the class 'foo':
<?php
class foo {
var $bar = 0;
function foo() {
$this->bar = 1;
}
}
?>
and another file that uses this class:
<?php
include_once 'foo.php';
start_session();
if(!isset($f)) {
$f = new foo();
session_register('f');
print "New object<br>";
}
else {
$f->bar = 5;
print "Object from session<br>";
}
?>
This code works, but if I:
1) put start_session() BEFORE the inclusion of foo.php
2) execute some code BEFORE the inclusion of foo.php
3) set session.auto_start to 1 in php.ini
I will receive this error:
Fatal error: The script tried to execute a method or access a property of
an incomplete object. Please ensure that the class definition foo of the
object you are trying to operate on was loaded _before_ the session was
started in ...
This is due to the fact that in the moment you execute even a single line
of code php starts the unserialization.
In practice, with this behaviour, it's impossible to work with object in
session with session.auto_start set.
Will there be a workaround or a solution to this problem?
