Hi all
Using PHP5, I am trying to save some properties of an object when it
is destroyed in its destructor, __destruct(). However, I have found
that the session variable is NOT stored unless I explicitly destroy
the object using unset(). If I leave php to finish executing the
script and automatically destroy the object, the destructor IS called,
however, the session variables are NOT saved. A quick code example
for clarity:
-----
class StateMachine {
public $stateVariable;
function __destruct() {
$_SESSION['state'] = $this->stateVariable;
}
}
$sm = new StateMachine();
if (isset($_SESSION['state'])) {
$sm->stateVariable = $_SESSION['state'];
} else {
$sm->stateVariable = 'foobar';
}
----
(please ignore the obvious bad coding standard of making that var
public and accessing it, this is for simplicity of the example).
Unless I do an unset($sm); at the end of a script like this, the
$_SESSION array will never contain the state=>foobar key/value.
Can anyone offer some insight into this?
Thanks!
Dave
