README

WHAT IS THIS?

    This module exploits the layered I/O support in Apache 2.0.

HOW DOES IT WORK?
    
    In Apache 2.0, you have handlers which generate content (like
    reading a script from disk). The content goes then through
    a chain of filters. PHP can be such a filter, so that it processes
    your script and hands the output to the next filter (which will
    usually cause a write to the network).

DOES IT WORK?

    Currently the issues with the module are:  
        * Thread safety of external PHP modules
        * The lack of re-entrancy of PHP. due to this I have disabled the 'virtual' 
          function, and tried to stop any method where a php script can run another php 
          script while it is being run.


HOW TO INSTALL

    This SAPI module is known to work with Apache 2.0.44.

        $ cd apache-2.x
        $ cd src
        $ ./configure --enable-so
        $ make install

    For testing purposes, you might want to use --with-mpm=prefork.
    (Albeit PHP also works with threaded MPMs. See Thread Safety note above)

    Configure PHP 4:

        $ cd php-4.x
        $ ./configure --with-apxs2=/path/to/apache-2.0/bin/apxs
        $ make install
   
    At the end of conf/httpd.conf, add:

        AddType application/x-httpd-php .php

    If you would like to enable source code highlighting functionality add:
    
        AddType application/x-httpd-php-source .phps
    
    That's it. Now start bin/httpd.

HOW TO CONFIGURE

    The Apache 2.0 PHP module supports a new configuration directive that
    allows an admin to override the php.ini search path. For example,
    place your php.ini file in Apache's ServerRoot/conf directory and
    add this to your httpd.conf file:

        PHPINIDir "conf"

DEBUGGING APACHE AND PHP
    
    To debug Apache, we recommend:

        1. Use the Prefork MPM (Apache 1.3-like process model) by
           configuring Apache with '--with-mpm=prefork'.
        2. Start httpd using -DONE_PROCESS (e.g. (gdb) r -DONE_PROCESS).

    If you want to debug a part of the PHP startup procedure, set a 
    breakpoint on 'load_module'. Step through it until apr_dso_load() is 
    done. Then you can set a breakpoint on any PHP-related symbol.
