You can still use constructors that have the same name as the class, at 
least for the time being. Just tested it with 4.4.0-dev HEAD and ZE2. If 
you have both a method with the same name as the class and a method called 
__construct(), the method with the class name will be used as the 
constructor and __construct() won't be used at all.

I actually did ;) however in retyping (due to circumstances) the code I
had misread the function call as c(&$a); and on replying didt notice my
mistake.

Appologies :P If you change the function call to c(&$a); you will notice
the output being "AAC" :P

Hello Dan,

Please run this code and check it output!
It will print "AAA", because in function c() you have COPY of object `$a`, NOT 
reference (with ZE1).

Just to prevent any misconception, the code executed through the ZE1 will
actually be "AAC" rather than "AAA". If you desired the latter result,
change "c($a);" to "c($b);".

Yeah, he is :-) ZE2 will still call the Class() function if the 
__construct() is not avaialble.

So current PHP4 classes will still work in ZE2?

There are archives of the Zend Engine 2 list at zend.com:
http://www.zend.com/lists.php

There is one big change with objects that will break BC.  Objects pass by
reference instead of value, both for function calls and assignments.  For
example:

name = 'C';
}

$a = new a;
$b = $a;

$a->name = "A";
print($a->name);
$b->name = "B";
print($a->name);
c($a);
print($a->name);
?>

In ZE1 you get "AAA". In ZE2 you get "ABC".

Any good links you could throw my way describing proposed changes?

You're wrong.

Of course, I could be too.

[PHP-DEV] Designing for PHP4 with PHP5 in mind...

[John Wells]

I'm preparing for a project in which I'll be porting and redesigning a
large, ugly Visual Basic/Sql Server app to a PHP/Mysql or Postgresql based
web application.

I'd like to code in a way that will be at the same time easily ported to
PHP5 and that will take advantage of PHP5's new object handling
efficiencies.  I've read varying reports of whether syntax will be
different.

Is there anything I should watch for, add, or specifically avoid while
coding this application to make the transition as easy as possible?

Thanks!
John
