<H2> PHP-ZIP Installation </H2>

<P>
  There have been many problems about the installation of the php-zip
  module. Since Mid of 2006 the php-zip module does not require the
  zziplib anymore - it uses its own implementation (which is a clean
  approach in a double sense - there are no source code comments).
  So, the following might possibly be only relevant for older
  installations.
</P>

<P> Chris Branch has been kind enough to jot down the points of a
    successful php-zip installation sending it to me in May 2006.
    I am quoting his text verbatim - again, I do not know whether
    it works or not as I am not using any PHP for real work.

<p><b>[***] Note:</b>
That step is the critical step that's not obvious.  Apparently,
when you build PHP as a static library and include the "--with-zip"
option, it creates a static library for PHP with an external dependency on
zziplib.a.  However, the Apache configure script and resulting Makefile
doesn't take this into account, so Apache won't link unless you hand-edit
the Apache Makefile.  (Maybe there's a better place to make this change so
that you don't have to re-fix Apache's Makefile each time you run Apache's
./configure.  However, I didn't spend the time to investigate that).
