Perhaps this will save someone the hours that it cost me to figure out how to go from a CGI version of PHP (through 4.2) to a module version on Apache 2 for Win2K: I've had a CGI versions of PHP 4 through several releases of Apache and the setup for that is really easy (assuming they both individually work): 0. Review php.ini (engine = On, et. al) 1. Move php4ts.dll into appropriate windows subdirectory (for me it's System32). The remaining 4 items are changes/additions to Apache's httpd.conf file: 2. Put index.php as the first argument to DirectoryIndex if you want Apache to automatically pick up index.php files Now add the following 3 lines: 3. AddType application/x-httpd-php .php 4. Action application/x-httpd-php "/php4/php.exe" 5. ScriptAlias /php4/ "c:/winapps/php/4.2/sapi/" 3 is so Apache will know .php files are special. 4 is so Apache will know what special program to run when it realizes it has a (.php) special file. 5 is so that Apache will know what directory that special program (php.exe) lives in. To go from the CGI to the Module version should be even simpler, right? But there is a HUGE gotcha. It's one of those You can't get there from here syndromes if you are using Apache 2.0.28 (or earlier, I presume). I needed to upgrade to 2.0.35 so that the required php (4.2) provided apache2filter.dll file would work with Apache2. So the final steps are as follows: Do steps 0-3 as written above. If you are upgrading, not installing, then back out steps 4 and 5 from above. 4) Add a line to the httpd.conf file: LoadModule php4_module c:/winapps/php/4.2/experimental/apache2filter.dll NOTE that this is not the php4apache.dll file of yore in the sapi directory (which I presume would work if you were doing this with Apache 1.3.x) -- http://www.php.net/manual/en/faq.installation.php http://master.php.net/manage/user-notes.php?action=edit+21094 http://master.php.net/manage/user-notes.php?action=delete+21094 http://master.php.net/manage/user-notes.php?action=reject+21094
