php_apache2_2.dll missing in current PHP 5.3 Windows builds [Windows]

Hi list,

one of my colleagues recently tried to manually install PHP 5.3 on Windows XP using Apache2 but failed because both php5apache2.dll and php5apache2_2.dll are missing in the most up to date archives on windows.php.net. We tried both VC6 and even VC9 build archives and both lack the above files, although the install.txt in the archives still mentions php5apache2_2.dll and the other one.
I tried to have a look at the Changelog to check if there has been a major change in the way PHP is used with Apache2, but the Changelog link on windows.php.net is dead.

Could someone have a look at this? Thanks a lot in advance!

Regards,

Sascha

hi,

Take the thread safe builds, not the non thread safe (NTS).

Cheers,

thanks for the quick reply, that helped a lot. Could you give me some background info what the NTS versions are used for?

Regards,

Sascha

If you are using cli, cgi, fast-cgi (or variants of these), then you
can use NTS. Each instance of the php interpreter is executed
completely separately to any other instance, so anything you do in
instance 1 is not going to interfere in instance 2. Specifically (as I
understand things), the allocation, reading and writing to memory is
done in a "non thread safe" way. This means it takes no account of
other processes attempting to read/write to that memory.

Where the php interpreter is executed with "shared memory", (for
example the defunct ISAPI for Windows and I assume by the reply you
got the apache handlers also), then 1 instance of PHP is loaded and
elements of the execution are split into threads (1 thread per request
is the norm here). In this form, the threads have to play nice when
they read/write memory. They have to be "thread safe".

OK. This is probably an extreme over simplification and probably
misses other important aspects, but is pretty much the general idea.

Where PHP is "loaded" into another process, then the thread safe
variant should be used. Where PHP is "executed" as a separate process,
then the non thread safe variant can be used and will have the slight
performance increase garnered from not having to handle
memory/resources/etc in a thread safe way.
