Bug description:Incorrect call to destructor when object stored in a session
Description:
------------
When an object is stored in the $_SESSION variable, the destructor is still
called at the end of the script. When the object is retrieved from the
$_SESSION on the next invocation, the constructor is not called, but the
destructor is again called.
To duplicate, place the attached code on a web server and load it. Then
press the reload button multiple times to see the results.
Test script:
---------------
<?php
class test {
private $construct_count = 0;
private $destruct_count = 0;
public function __construct() {
$this->construct_count++;
echo "Constructor called.<br>\n";
}
public function __destruct() {
$this->destruct_count++;
echo "Destructor called.<br>\n";
}
}
session_start();
?>

<?php

$_SESSION['test'] = new Test();
}
else
echo "Session found<br>\n";
echo "<pre>\n";
print_r($_SESSION);
echo "</pre>\n";
?>
</body>
</html>
Expected result:
----------------
Session not found
Constructor called.
Array
(
[test] => test Object
(
[construct_count:test:private] => 1
[destruct_count:test:private] => 0
)
)
After second and subsequent invocations:
Session found
Array
(
[test] => test Object
(
[construct_count:test:private] => 1
[destruct_count:test:private] => 0
)
)
Actual result:
--------------
After first invocation:
Session not found
Constructor called.
Array
(
[test] => test Object
(
[construct_count:test:private] => 1
[destruct_count:test:private] => 0
)
)
Destructor called.
After second and subsequent invocations:
Session found
Array
(
[test] => test Object
(
[construct_count:test:private] => 1
[destruct_count:test:private] => 1
)
)
Destructor called.
Note: destruct_called increments on each invocation. construct_count does
not.
