i know this thread started off about a performance comparison, but it is already grown into much more. suffice it to say that i consider the oop capacity of php4 nothing more than a stepping stone on the way to php5. i dont know of all the oop languages out there. mostly i have worked w/ c++ and java (and a little .net and a tiny bit of delphi) when it comes to oop. all of those languages have ppp; which i consider to be fundamental to an oop language; but alas php is not an oop language; it merely supporst features of an oop language. per statements on php.net.
then again javascript is supposedly oop, and i know it doesnt support ppp; so we would really have to dig deeper for a definition of 'basic oop' / 'true oop' etc. from a personal standpoint i have been leraning how to leverage the power of the interface construct for 1. on top of that, well i think no ppp is madness... but again, thats nothing formal :) -nathan On 8/25/07, Robert Cummings <[EMAIL PROTECTED]> wrote: > > On Sat, 2007-08-25 at 11:09 -0500, Larry Garfield wrote: > > On Saturday 25 August 2007, Robert Cummings wrote: > > > > > Rewriting?
