<?php/* this seems like a pretty good way to show you the difference between threads that are syncrhonized with mutex and those that aren't *//* will show 50 very neat rows <-.........-> then 50 threads doing the same thing with no mutex */class MyWorkerThread extends Thread {public function __construct($limit, $mutex, $id){$this->limit = $limit;$this->mutex = $mutex;$this->id = $id;}public function run(){if($this->mutex)$locked=Mutex::lock($this->mutex);printf("%s#%lu:<-", !empty($locked)?"Y":"N", $this->id);$i=0;sleep(rand(1,3));while($i++<$this->limit){echo ".";}printf("->\n");if($this->mutex)Mutex::unlock($this->mutex);return true;}}$timer = microtime(true);/* create and lock a mutex */$mutex = Mutex::create(true);/* create workers */$workers = array();for($i=0;$i<10;$i++){$workers[$i]=new MyWorkerThread(rand(30, 100), $mutex,$i);/* they cannot go anywhere, I have the mutex */$workers[$i]->start();}printf("Release the (muzzled) hounds ... :\n");Mutex::unlock($mutex);foreach($workers as $i=> $worker)$workers[$i]->join();printf("Muzzled: %f seconds\n", microtime(true)-$timer);/* please remember to destroy mutex and condition variables */Mutex::destroy($mutex);$timer = microtime(true);/* same again, no mutex */printf("Now no mutex ... :\n");$workers = array();for($i=0;$i<10;$i++){$workers[$i]=new MyWorkerThread(rand(30, 100),null,$i);/* they cannot go anywhere, I have the mutex */$workers[$i]->start();}foreach($workers as $worker)$worker->join();printf("Dribbling: %f seconds\n", microtime(true)-$timer);?>

改了一下,可以明显看到用了Mute会是按照顺序执行,而不用Mute,则是同时多线程执行的。
