Starting with the PHP5.2.10 version (now available in PHP5.2.10 and 5.3 two versions), there are none-thread safe and Thread safe two versions to choose from, what is the difference between these two versions, and how should they be chosen as users? The following friends will tell you.

First of all, in the literal sense, none-thread safe is non-thread-safe, do not thread security at execution time, thread safe is threaded, thread security is performed, to prevent new requirements to start a new thread of CGI The execution method exhausts the system resources.

Let's look at two ways of executing PHP: ISAPI and fastcgi. FastCGI execution is performed in a single thread, so there is no need for thread security checks, and removing thread security checks can improve execution efficiency, so if PHP is executed in FastCGI (whether with IIS 6 or IIS 7), it is recommended to download, execute Non-thread Safe php (php Two files are packaged in two ways: MSI, zip, download the zip kit). Thread safety checks are prepared for the ISAPI way of PHP, because there are many PHP modules that are not thread-safe, so you need to use the thread safe PHP.

Speaking of which, you should know how to choose which version of PHP. None-thread safe or Thread safe, which would you choose?

The version of PHP under Windows is updated quickly, the newest is PHP7 already, now the version of Windows can be downloaded in PHP official PHP for Windows (http://windows.php.net/download/), When downloading the same version has VC9 x86 Non thread safe, VC9 x86 thread safe, VC6 x86 Non thread safe, VC6 x86 thread safe and other four versions. So what's the difference between these versions?

The version of VC9 was compiled with Legacy VS 2008, and the VC6 version was compiled with Legacy VS6.

If you are using iis+php under Windows, you need to download the VC9 version.
If you are using apache+php under Windows, you need to download the VC6 version.

Non thread safe refers to non-thread safety, thread safe refers to threading security.

If you are using ISAPI to run PHP, you must use the thread safe version, while running PHP in fastcgi mode, there is no need to use thread security, with none thread safe (NTS, non-thread-safe) Version to better improve efficiency.

This way, how to choose your PHP version of the appropriate, to download the appropriate PHP for your system.
