A further note:

These are example of PHP internals that should be (and are)  
transparent to someone programming in the language.  But the problem  
is that the consequences of these internal decisions drastically  
affect the performance of a particular script.  The pro and con of a  
high-level programming language.

It would be nice if there was a place where some of these internals  
were documented as they relate to aiding in a PHP programmer.  Does  
anyone know of such a site (besides random scattered comments within  
the PHP manual itself)?
