-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?
-
- It is experimental as interfaces in Apache 2.0 might change in the
- future.
-
-HOW TO INSTALL
-
- This SAPI module is known to work with Apache 2.0.40.
-
- $ 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.)
-
- 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 recommened:
-
- 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.
-
-TODO
-
- PHP functions like apache_sub_req (see php_functions.c)
- Protocol handlers
- Passing script data to engine without temporary file
