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 in locale settings while a

script is running, though the script itself never called
|

<span class="function"><strong>setlocale()</strong></span>. This happens due to other scripts
|
||
running in different threads of the same process at the same time,

changing the process-wide locale using <span class="function"><strong>setlocale()</strong></span>.
