MSI package for installing non-thread-safe build of PHP. The PHP source code is available at http://svn.php.net/viewvc/. The PHP installer source code is available at http://svn.php.net/viewvc/php/win-installer/.
Just successfully installed PHP 5.4. on IIS7 Make sure you install the non-thread safe version and run php-win.exe rather than looking for a msi file. Also you need to edit a php.ini file from php.ini-production
