Usage

Run only in one instance, do not wait for lock to become available:

$lock = new \EdgarPE\Lock\Lock(__FILE__);
if ($lock->acquire(false)) {
    echo posix_getpid(), "\n";
}

Wait for lock to become available:

$lock = new \EdgarPE\Lock\Lock(__FILE__);
if ($lock->acquire(true)) {
    echo posix_getpid(), "\n";
}

Synchronized PHP callable, something similar like Java synchronized methods:

$lock = new \EdgarPE\Lock\Lock(__FILE__);
$pid = $lock->synchronized(function () {
    return posix_getpid();
});
echo $pid, "\n";
