Choose Web Server


IIS is built in to Windows. On Windows Server, the IIS role can be added via the Server Manager. The CGI Role Feature needs to be included. On Windows Desktop, IIS has to be added via the Control Panel's Add/Remove Programs. The Microsoft documentation has » detailed instructions. For desktop web apps and web-development, IIS/Express or PHP Desktop can also be used.

There are several builds of Apache2 for Windows. The Apache builds of ApacheLounge are recommended, but other options include XAMPP, WampServer and BitNami, which provide automatic installer tools. PHP can be used on Apache through mod_php or mod_fastcgi. mod_php requires a TS build of Apache built with same version of Visual C and same CPU (x86 or x64).

Choose Build

Windows builds can be downloaded from » All builds are optimized (PGO), and QA and GA releases are thoroughly tested.

There are 4 types of PHP builds:

  • Thread-Safe(TS) - for single process web servers, like Apache with mod_php

  • Non-Thread-Safe(NTS) - for IIS and other FastCGI web servers (Apache with mod_fastcgi) and recommended for command-line scripts

  • x86 - for 32-bits systems.

  • x64 - for 64-bits systems.
