Architecture

It is recommended to use x64 builds of PHP as almost all Windows installations currently support x64.

Thread Safety

NTS builds are for single-threaded use cases, typically PHP running via FastCGI or on the CLI. TS builds support multithreaded SAPIs and are intended for PHP loaded as a web server module. So, if you want to use PHP as FastCGI with IIS, use the Non-Thread Safe (NTS) builds of PHP, or if you want to use the Apache HTTP Server, use the Thread Safe (TS) builds of PHP.

Visual Studio Versions

The builds below are built using Visual Studio 2019 (VS16) or Visual Studio 2022 (VS17) compiler. They require the Visual C++ Redistributable for Visual Studio 2015-2022 x64 or x86 installed.
