That text is simply telling Apache that PHP exists, what extensions are PHP files, and the location/name of the PHP binary. That text is actually outdated, see below for the proper commands:
PHP as an Apache module:
- copy php4apache.dll into the /modules sub-folder in the directory you installed apache into
- add the following line to httpd.conf:
LoadModule php4_module /modules/php4apache.dll
PHP as a CGI process
- add the following lines to httpd.conf:
ScriptAlias /php/ "c:/php/"
Action application/x-httpd-php "/php/php.exe"
For both installation types:
- copy php4ts.dll to your %SYSTEM% folder (c:\windows\system or c:\winnt\system32)
- edit php.ini-dist, php.ini-optimized, or php.ini-recommended and copy it to %WINDIR% (c:\windows or c:\winnt) as php.ini
- add the following lines to httpd.conf:
AddType application/x-httpd-php .php .php3 .phtml
AddType application/x-httpd-php-source .phps
Now restart Apache. The ScriptAlias line assumes you installed PHP into c:\php. Change the path to suit the location which you actually installed PHP into. HTH.
