PHP 5.0 Reviews kvcindia

Here are a few bits of information I collected at PHP Forum

It is estimated than no more than 5% of the servers running PHP have switched to PHP 5 yet
PHP 5.0 is a feature release, not a performance release. Therefore it is slower than PHP 4.x. Therefore it makes no sense running apps designed for PHP 4 on PHP 5.0.
PHP 5.1 should almost match the performance of PHP 4.4
Rasmus will probably migrate Yahoo's servers from PHP 4 to PHP 5 once PHP 5.1 has undergone a few weeks without any major issue.
It is extremely painful for everyone to make code that works on PHP 5 as well as PHP 4, especially because you cannot redefine the clone statement in PHP 4 for compatibility.
Okay, that's all I can recall right now!
