In this week's PHP Weekly Summary from Zend there are only a few items mentioned, but one of them sparked a debate, even on this site.

First, there's a note about a fix for the constuctor declaration issues they were seeing (the transition from a PHP5 _construct() to a PHP4 constructFunction()) that wasn't allowing the fall-back to work correctly. Also mentioned this week is a discussion about the serialize() function being somewhat slow (as compared in the example to a foreach loop that does the same thing). No one has taken up the charge to correct it yet, but the evidence is there.

And, finally, the topic that everyone's been buzzing about lately - the studlyCaps issue brought up by John Coggeshall. A listing has even been made of the reasons to sway one way or another. Of course, a definite decision has not been made yet...
