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 - - Get the latest Apache 2.0 alpha or the CVS code and install it. - - $ 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: - - <Files *.php> - SetOutputFilter PHP - SetInputFilter PHP - </Files> - - That's it. Now start bin/httpd. - -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. Set the variable "ONE_PROCESS" to 1 and export it before - starting Apache/a debugger. - - 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 - Syntax Highlighter (relies on files as well) diff --git a/sapi/apache2filter/apache_config.c b/sapi/apache2filter/apache_config.c deleted file mode 100644 index 178253d825..0000000000 --- a/sapi/apache2filter/apache_config.c +++ /dev/null @@ -1,164 +0,0 @@ -/* - +----------------------------------------------------------------------+ - | PHP Version 4 | - +----------------------------------------------------------------------+ - | Copyright (c) 1997-2002 The PHP Group | - +----------------------------------------------------------------------+ - | This source file is subject to version 2.02 of the PHP license, | - | that is bundled with this package in the file LICENSE, and is | - | available at through the world-wide-web at | - | http://www.php.net/license/2_02.txt. | - | If you did not receive a copy of the PHP license and are unable to | - | obtain it through the world-wide-web, please send a note to | - | license@php.net so we can mail you a copy immediately. | - +----------------------------------------------------------------------+ - | Author: Sascha Schumann <sascha@schumann.cx> | - +----------------------------------------------------------------------+ - */ - -#include "php.h" -#include "php_ini.h" - -#include "apr_strings.h" -#include "ap_config.h" -#include "util_filter.h" -#include "httpd.h" -#include "http_config.h" -#include "http_request.h" -#include "http_core.h" -#include "http_protocol.h" -#include "http_log.h" -#include "http_main.h" -#include "util_script.h" -#include "http_core.h" - -#ifdef PHP_AP_DEBUG -#define phpapdebug(a) fprintf a -#else -#define phpapdebug(a) -#endif - -typedef struct { - HashTable config;
