The directory naming format is: [php-version]-[ts]

Here ts is a thread safety option:
    * NTS: non-thread-safe binary (to be used with Zend Server, for example)
    * TS:  thread-safe binary

DLL for your platform can be found in the corresponding directory.

All the binaries are built with Windows Platform SDK (MS Visual C++ 2008)
on my home XP86 box (Windows XP 32 bit).

Have a lot of fun!
