PHPThe introduction of the Thread Safe main target is the Windows next to IIS run PHP the situation, because Windows the frequent application process overhead, so in the Windows multi-threaded way to operate, this time PHP need Thread Safe version. Under the Linux system, PHP Most of the cases are run in multi-process mode, so it can be used directly None Thread Safe .

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.

If there are multiple threads, use the thread-safe version;

If there is only one thread, use a non-thread-safe version.
