Many times along with ASP.NET and MS SQL you will need PHP and MySQL for your web applications. Most of the best ASP.NET hosting companies
offer preinstalled PHP and MySQL with their plans. Anyway, there could be possible to install manually the PHP on your hosting server.You can easily install PHP using Microsoft® Web Platform Installer. It completely automates setting up IIS, FastCGI, and the latest version of PHP from the php.net Web site. There are two builds for each PHP version: one is thread-safe, and one is not. The other option is to use the Windows Zip file from the PHP Web site (http://www.php.net/downloads.php).
Install PHP using Windows Installer
With Windows Installer you can easily install PHP, but by default, no extensions are installed. You can manually install all of the extensions, but this results in an unstable system because some of the extensions can conflict with others. It is generally easier to use the Zip file installation.
Install PHP via Zip File
The Zip file installation installs many of the extensions that are available for the Windows Installer version. To install the PHP follow the next steps:1. Download the latest non-thread-safe Zip file package.2. Unpack the files to a directory of your choice (by example, C:\PHP) on your IIS server.3. Open the Php.ini file in a text editor, then uncomment and modify settings as follows: – fastcgi.impersonate = 1. – cgi.fix_pathinfo=0 – cgi.force_redirect = 0. – Set open_basedir to point to a folder or network path where the content of the Web site(s) is located. – Set extension_dir to point to a location where PHP extensions reside. – error_log=”C:php_errors.log”5.
