PHP v5.2.17 for windows (isapi is recommended for independent servers, generally win2003 iis6 is used)

PHP v5.2.17 for windows, generally installed in win2003 iis6 isapi mode, PHP v5.2.17 fixes the vulnerability of the previous version. Installing this version is strongly recommended. Note: This version is thread-safe and generally runs in isapi mode, but it is recommended to use the thread-safe version if running in cgi.

There are two ways to execute PHP: ISAPI and FastCGI.

ISAPI execution mode is used in the form of DLL dynamic library, can be executed after the user request, after processing a user request will not disappear immediately, so the Thread safety check is needed to improve the execution efficiency of the program, so if you use ISAPI to execute PHP, it is recommended to choose Thread Safe version;

The FastCGI execution mode is a single Thread to perform operations, so there is no need for thread safety checks, removing the protection of thread safety checks can improve the execution efficiency, so if you use FastCGI to execute PHP, it is recommended to choose Non Thread Safe version.
It is not officially recommended that you use Non Thread Safe in production, so we chose the Thread Safe version of PHP to use.

In order to further improve the security of PHP programs, we require all users to upgrade to PHP5.2.17 or above, as follows:
(For users who have installed ZEND, you need to delete ZEND, you can select the default when deleting zend, you can install ZEND by default after the successful upgrade of PHP.)
