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 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.
