I will report a snippet from http://php.net/setlocale
Warning
The locale information is maintained per process, not per thread.
If you are running PHP on a multithreaded server api like IIS or Apache
on Windows you may experience sudden changes of locale settings while a
script is running although the script itself never called setlocale()
itself. This happens due to other scripts running in different threads
of the same process at the same time changing the processwide locale
using setlocale().
I spent about 2 seconds before thinking: can it really be? I mean, is
there no way to set locale info per thread? And after a brief web
search I came up with this keyword: _configthreadlocale
Read more at
http://msdn2.microsoft.com/en-us/library//26c0tb7x(VS.80).aspx (beware,
this page is very slow or their servers are anyway).
Looks like this function exists since Windows 95 and guess what it
does: it affects the behaviour of the locale functions so that _each
thread will have indipendent locale settings_.
So, I though: WHY? Why does not PHP use such function in the windows
binding?
Let's be clear, I don't think to have found a solution that (the great)
PHP developers could not find, but I would like to know why they did
not fix the bad behaviour of PHP's setlocale() function using the
_configthreadlocale() win32 function, there must be some reason I
really could not think about up to now.
I really hope somebody can point me to something to read about this
topic (I found pretty nothing up to now) or better directly explain it
to me.
Thank you
