You may still have the original version of PHP4 for iTools.  In this 
version the libraries were compiled in statically.  The newest 
version of PHP4 for iTools which can be downloaded at 
http://iris.sysci.org/tenon/PHP4-4.0.1pl2.pkg.tar.gz is a dynamic 
build.  In this version, the PHP4 package and all of the libraries 
(i.e. PDFlib, GDlib, FreeType which were first built dynamically) 
were compiled dynamically.  You can see the dynamic libraries in the 
folder "/usr/local/libs" if you issue the command "ps -alx" then you 
will notice the Apache processes are running around 600K, now if you 
hit a PHP enabled page and then depending on which library you use, a 
pdf test page is always nice for this demo, you will see a jump in 
the process footprint to around 2.5 - 3.5M.

It sounds as if some people on the list have been asking about adding 
new libraries to PHP, this is not possible without rebuilding the 
entire PHP DSO module.  PHP is not like Apache in the sense that 
modules can be easily added and removed without re-linking at the 
minimum.  PHP does seem to be making the move to this ideology with 
the introduction of PHP4.

If you are planning to build your own copy of PHP4, we built it 
against our Apache 1.3.12 source, and then linked it against the 
dynamic libraries that we had to compile ourselves.
