Variables and References Article
A week ago PHP 4.4.0rc1 was released - this release addresses major problems with references in PHP. But not many people are fully aware of how variables and references actually work in PHP. This is where my latest article in PHP Architect comes into play. It explains in details how assigning variables, passing variables to functions and returning variables from functions work - both by-value and by-reference.
Comments
Thanx for the article, it gives a deep insight into PHP internals.
However, there's one issue left unspoken, that is PHP5 objects internal model. It's obvious they're not just variables...
How are they implemented actually?
Consider the following lines in PHP5:
$a = new Foo(); $b = $a;
Is it equivalent internally in PHP5 to this:
$a = new Foo(); $b =& $a;
If not what the difference? Is it actually "healthy" to use & with objects in PHP5? Is there speed overhead?
I'm asking all these questions because we're using PHP5 with applications which were written solely for PHP4 yet using OOP. These applications use & almost everywhere and i wonder how PHP5 treats it internally....

It's good to see that more and more people are realising that the Web can be for-good, without all the enshittification.
That's why I'm happy to see endeavours like phpc.tv springing up, and helping out where I can.
Taking back the control of how the Web is for people, by people, without big tech making it all shit.
