What is the difference between the two versions of safe and what are the differences between the two versions, and how should they be chosen as users? The following friends will tell you.

safe is thread-safe, and thread security checks are performed to prevent new requirements from exhausting system resources as the CGI execution of new threads starts .

Let's look at two ways of executing PHP: ISAPI and fastcgi. FastCGI execution is performed with a single thread, so there is no need for thread security checks, but the protection of thread security can improve execution efficiency, so if

Two files are packaged in two ways: MSI, zip, download 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.
