Installing as a CGI binary

If you unzipped the PHP package to C:\php\ as described in the Manual Installation Steps section, you need to insert these lines to your Apache configuration file to set up the CGI binary:

ScriptAlias /php/ "c:/php/"
AddType application/x-httpd-php .php

# For PHP 4
Action application/x-httpd-php "/php/php.exe"

# For PHP 5
Action application/x-httpd-php "/php/php-cgi.exe"

# specify the directory where php.ini is
SetEnv PHPRC C:/php

If you would like to present PHP source files syntax highlighted, there is no such convenient option as with the module version of PHP. If you chose to configure Apache to use PHP as a CGI binary, you will need to use the show_source() function. To do this simply create a PHP script file and add this code: <?php show_source("original_php_script.php"); ?>. Substitute original_php_script.php with the name of the file you wish to show the source of.

Installing as an Apache module

You should add the following lines to your Apache httpd.conf file:

AddType application/x-httpd-php .php

# For PHP 4
LoadModule php4_module "c:/php/sapi/php4apache.dll"

# For PHP 5
LoadModule php5_module "c:/php/php5apache.dll"

# specify the directory where php.ini is
SetEnv PHPRC C:/php

You may find after using the Windows installer for Apache that you need to define the AddModule directive for mod_php4.c. This is especially important if the ClearModuleList directive is defined, which you will find by scrolling down a few lines. You will see a list of AddModule entries, add the following line at the end of the list: AddModule mod_php4.c. For PHP 5, instead use AddModule mod_php5.c

If you would like to use the source code highlighting feature, you need to add the following line to your httpd.conf: AddType application/x-httpd-php-source .phps. This should be inserted at the same place where you inserted AddType application/x-httpd-php .php above). With this setup, all files served with the .phps extension will be syntax highlighted for the browser.
