I verified with following script. Session module is PHP_SESSION_NONE status
after session_destroy().
<?php
class Bug {
private $i = 0;
public function __construct() {
session_start();
if ( isset( $_SESSION['i'] ) ) {
$this->i = $_SESSION['i'];
}
$this->i ++;
$_SESSION['i'] = $this->i;
}
public function printLink() {
echo '<a href="/?' . SID . '">Bug</a>: ' .
$this->i . PHP_EOL;
}
public function __destruct() {
session_destroy();
echo 'destruct'.PHP_EOL;
}
}
$bug1 = new Bug();
$bug2 = new Bug();
$bug1->printLink();
unset($bug1);
var_dump(session_status());

I think you can still call session_destroy() or any other session functions using
register_shutdown_function(). You even can work around that with hidden iframes, if you want to
destroy a class before the main php end, but I think this is not the case you are looking for.

Description:
------------
Actually I'm talking about beta2 of PHP5, but it wasn't listed.
I think the __destruct() method should do things like cleaning up any resources. So it would be nice
if I could destroy Sessions which are empty. But the Session Handler for closing the Session is
called before the __destruct() methods.
Reproduce code:
---------------
class Bug {
private $i = 0;
public function __construct() {
session_start();
if ( isset( $_SESSION['i'] ) ) {
$this->i = $_SESSION['i'];
}
$this->i ++;
$_SESSION['i'] = $this->i;
}
public function printLink() {
echo '<a href="/?' . SID . '">Bug</a>: ' .
$this->i;
}
public function __destruct() {
if ( $this->i > 4 ) {
session_destroy();
}
}
}
$bug = new Bug();
$bug->printLink();
Expected result:
----------------
I would expect that the Session is still active and can be manipulated in any __destruct() method.
Actual result:
--------------
PHP's Session Handler for closing the Session is called before any __destruct method. So I
can't do anything with the Session in the __destruct method.
