Threaded::synchronized

(PECL pthreads >= 2.0.0)

Threaded::synchronized同步控制

说明

public mixed Threaded::synchronized ( Closure $block [, mixed $... ] )

在发起调用的线程上下文中获取对象同步锁,然后同步执行代码块

参数

block

要执行的代码块

...

传送给代码块的不定长参数

返回值

代码块的返回值

范例

Example #1 同步

<?php
class My extends Thread {
    public function 
run() {
        
$this->synchronized(function($thread){
            if (!
$thread->done)
                
$thread->wait();
        }, 
$this);
    }
}
$my = new My();
$my->start();
$my->synchronized(function($thread){
    
$thread->done true;
    
$thread->notify();
}, 
$my);
var_dump($my->join());
?>

以上例程会输出:

bool(true)

Threaded::synchronized() allows you to safely set or read synchronization conditions and act upon them (using ::wait() and ::notify()) knowing that only one call to synchronized() on the referenced object can be executed at a particular time, other calls from different thread contexts will block until the path is cleared by a call to ::wait() inside your ::Synchronized() closure.
