course __destruct (in php5) is not meant to be called by "userland" (as
you called it). I just want to make sure all objects are stored as they
should when a script ends. This kind of wrapper method is of course "lame"
as you called it, but it would do what I need it to do, thought it is lame
:) This is just to "simulate" something that is missing in PHP 4 and that I
as a standard am working with. To close down database connections etc are
not the purpose at this stage for me as PHP will take care of these
resources by it self.
, back to Sunday afternoon programming :)

Hi,
Yes I have been reading both sections and is aware of the different
sections
for PHP 4 and 5. I was just hoping there was something missing in the
manual
for PHP 4 as I'd love to have a __destruct method to work with. There are
other solutions around this. Basically I just want to make sure that the
objects that have a save() method are saved correctly before they are
destroyed. With PHP 4 I just need to do this "manually". I could probably
just write a cleanup function that will be executed in the end of each
scripts that checks if objects have a save() method and then executes that
one. better: Check if there is a method __destruct() existing and use
that when cleaning up. Then it would be forward compatible with PHP 5 as
well :)
alternative:
have each object register itself with a 'stack' and register a shutdown
function
which automatically calls the save() method of each object in said stack
be careful to always using the 'reference' operator.
I wouldn't bother to try and make it php4/php5 compatible - the reference
operator
of itself will make sure that you have to change the code for php5, besides
that __destruct()
is not 'meant' to be called by userland code - and as far as I can tell it's
a bit lame (there is no garanteed order of destruction so you can't rely on
other object still
being around and IIRC [somebody correct me if I'm wrong please] things like
DB connections
are also gone by the time __destruct() is called - the same goes for access
to STDIN, STDUT, etc.

In PHP 4 the constructor has the same name as the class (like C++). See
There is no destructor in PHP 4.

PS The manual has two sets of P documentation: one for PHP 4 &
another for PHP 5. Make sure you're viewing the right set.
