Look at your own computer, it is 32-bit to choose X86, if it is a 64-bit operating system, choose X64, because it is a windows system, so choose the safe thread version of Thread Safe, here we choose a compressed file Zip to download.

Installation

After downloading, it is a compressed package and unzipped directly to the appropriate directory. Here I create a PHP folder on disk D and extract it into it, which means that the installation directory is D:\ PHP.

Configuration

Environment variable

The first step in installing the php service is to add environment variables

Right-click on this computer = > Properties = > Advanced system Settings = > Environment variable = > system variable = > path
