First, literally, None-Thread Safe means non-thread security, and no Thread security check is performed during execution. Thread Safe means thread security, the thread security check is performed to prevent the CGI execution method of the new thread from consuming system resources when there are new requirements.

Let's take a look at two PHP execution methods: ISAPI and FastCGI. FastCGI executes operations in a single thread, so it does not need to perform thread security checks. apart from the thread security check protection, it can improve the execution efficiency, if you use FastCGI (whether with IIS 6 or IIS 7) to execute PHP, we recommend that you download and execute non-thread safe PHP (the PHP binary path has two packet encoding methods: msi, zip, please refer to the zip suite ). The Thread security check is prepared for PHP in The ISAPI mode. because many php modules are not Thread-Safe, Thread Safe PHP is required.

Speaking of this, you should know how to select the PHP version. None-Thread Safe or Thread Safe. which one do you choose?

Windows PHP version updates quickly, the latest is PHP7 has, the current Windows version can be downloaded in PHP official PHP For Windows (http://windows.php.net/download, during the download, the same version includes four versions: VC9 x86 Non Thread Safe, VC9 x86 Thread Safe, VC6 x86 Non Thread Safe, and VC6 x86 Thread Safe. So what are the differences between these versions?

The version of VC9 is compiled with legacy VS 2008, and the version of VC6 is compiled with legacy VS6.

If you are using IIS + PHP in windows, you need to download the version of VC9.
If you are using Apache + PHP in windows, you need to download the VC6 version.

Non-Thread Safe refers to Non-Thread security, and Thread Safe refers to Thread security.

If you use ISAPI to run PHP, you must use the Thread Safe version. if you run PHP in FastCGI mode, there is no need to use Thread security check, using the None Thread Safe (CNT, non-Thread secure) version can improve the efficiency.

In this way, you can easily select the applicable PHP version and download the PHP suitable for your system.
