在 PHP 中什么是线程安全或非线程安全？

Question

I saw different binaries for PHP, like non-thread or thread safe? What does this mean? What is the difference between these packages?

Answer 1

For me, I always choose non-thread safe version because I always use nginx, or run PHP from the command line.

The non-thread safe version should be used if you install PHP as a CGI binary, command line interface or other environment where only a single thread is used.

A thread-safe version should be used if you install PHP as an Apache module in a worker MPM (multi-processing model) or other environment where multiple PHP threads run concurrently.
