Example #1 Mutex Locking and Unlocking

<?php /** You cannot use the "new" keyword, a Mutex is not a PHP object **/ $mutex = Mutex::create( /** You can now lock the mutex in any context **/ var_dump(Mutex::lock($mutex) /** It is invalid to attempt to destroy a locked Mutex **/ var_dump(Mutex::unlock($mutex) /** Always destroy mutex you have created **/ Mutex::destroy($mutex ?>
