Example #1 Grouping together an atomic integer's operations (requiring a mutex lock)
<?php
use pht\AtomicInteger;
$atomicInteger = new AtomicInteger(2);
// assumes $atomicInteger is being used by multiple threads
$atomicInteger->lock();
$atomicInteger->set($atomicInteger->get() * 2); // double the value
$atomicInteger->unlock();
var_dump($atomicInteger->get());
以上例程会输出：
int(4)
