The difference between php non-thread-safe and thread-safe
Starting from PHP5.2.10 version, there are two versions: None-Thread Safe and Thread Safe What are the differences between these two versions, and how should users choose?
Let’s understand it literally. None-Thread Safe means non-thread safety, and no thread (thread) security check is performed during execution;
Thread Safe means thread safety, and it will be checked during execution. Thread safety checks to prevent CGI execution from consuming system resources by starting new threads upon new requests.
Let’s look at the two execution methods of PHP: ISAPI and FastCGI.
FastCGI execution method uses a single thread to perform operations, so there is no need to perform thread safety checks. Removing the protection of thread safety checks can improve execution efficiency. Therefore, if FastCGI (with IIS) is used to execute PHP , it is recommended to download PHP that executes non-thread safe (PHP binary files have two packaging methods: msi and zip, please download the zip package).
The thread safety check is prepared for ISAPI PHP. Because many PHP modules are not thread safe, you need to use Thread Safe PHP (with apache).
If you are still unclear, then just know whether you are php apache or php iis combination
non-thread-safe non-thread-safe and IIS matching environment
thread -safe thread safety and apache matching environment
In addition, PHP also has VC6 VC9 version distinction
VC6 and VC9, one supports apache and the other supports IIS
VC9 cannot be used on apache The problem is, if you use iis, you must use vc9. If you use apache, both vc6 and vc9 can be used.
