Just because I find it frustrating how obtuse the install directions for PHP are…
- Download and install Apache
 - Download, install, and configure MySQL
 - Download PHP and unzip to somewhere like “C:\php5.2”
 - Update php.ini file in PHP install directory; update or uncomment the following line:
- extension=php_mysql.dll
 - SMTP = localhost
 
 - Copy these two files from the php dir to the apache\bin dir:
- php5ts.dll
 - libmysql.dll
 
 - Update your httpd.conf to have the following lines (they can be at the bottom):
AddType application/x-httpd-php .php
PHPIniDir "C:/php5.2/"
LoadModule php5_module "C:/php5.2/php5apache2_2.dll"
 - Restart apache service; test with phpinfo()
