Examples? Links? More information on this? The fact is that on
php.internals there are discussions to reduce the number of maintained
development threads. In the not-so-far future they will reduce the
manpower put into backporting bugfixes to the PHP4.x development branch
since 5.x is the HEAD revision and everything is first fixed there. I
think all "old" stuff is just as mature in PHP5 as you know it from PHP4
and if some errors are found they are likely to be fixed more quickly
for the 5.x release. The "new" stuff (that wasn't there before 5.0)
almost certainly has more bugs since it's younger but that's no argument
since this isn't relevant for old projects.

The OOP features of PHP3 were nothing more than some kind of crippled
namespaces for functions. PHP4 improved on that but PHP5 was the version
to bring real OOP features to the language. It's the first versions to
feature destructors and the possibility to overload parts of the Zend
Engine for iterators or array access. You couldn't do

$adr=new DB_Adress(12); // loads the adress with ID 12 from DB
$adr['street']='Market Street'; // change the property
//...
// end of script, save changes to DB
?>

before PHP5.

Nice article. Read it myself a few days ago (wasn't the link featured on
Slashdot? *g*). Delaying upgrades might be true for running systems. But
there's nothing keeping you from running both PHP4 and PHP5 on the same
machine for different projects. And if you start a project from scratch
PHP5 is the way to go.
