pthreads-php What does thread safety mean?

PHP has such an option when compiling the installation--enable-maintainer-zts English explanation is enable thread Safety-for code maintainers only!!
Abstract understanding thread safety for code maintenance personnel!
So what does that mean?

Thread-Safe Explanation:
From the PHP5.2.10 version, there are none-thread safe and Thread safe two versions of the choice, what is the difference between the two versions, as a user should be how to choose? 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.

Talk about your questions, first of all this is related to multithreading, if you want to use multithreading (PHP, such as: pthreads), then this parameter is necessary.
