php 4 v php 5

Hi: Curt. said:

PHP 4.4.2 - Released Jan 13 2006 php 5.1.2 - Released Jan 12 2006 PHP 5.0.5 - Released Sept 6 2005 I wouldn't expect any more releases of 5.0.x version.

Pardon my ignorance -- I have enough problems pounding out code to spend time following what's happening at the higher levels. But, considering the above statement, are there continuing development paths for both php 4 and 5 independently? If so, what's the distinction between the two, oop? And if so, what about non-oop stuff -- do they share common libraries, or what? Generally, how does all of this fit together? Thanks. tedd -- -------------------------------------------------------------------------------- http://sperling.com
