Threaded::notify — Synchronization
向对象发送唤醒通知
此函数没有参数。
布尔值,表示操作是否成功
Example #1 等待和唤醒
<?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)

Seems like some operators dont work.
f.e. $thread->array[] = 1; fails
a simple test:
<?php
class My extends Thread
{
public
$array = array('default val 1', 'default val 2'),
$msg = 'default',
$stop = false;
public function run()
{
while(true)
{
echo $this->msg . PHP_EOL;
if(count($this->array) > 0){
foreach($this->array as $val){
var_dump($val);
}
$this->array = array();
}
$this->synchronized(
function($thread){
if(count($this->array) < 1){
$thread->wait();
}
},
$this
);
echo PHP_EOL;
if($this->stop){
break;
}
} // while
}
}
$my = new My();
$my->start();
sleep(1); // wait a bit
// test 1 - $thread->array[] = 1;
$my->synchronized(
function($thread){
$thread->msg = 'test 1';
$thread->array[] = 1;
$thread->notify();
},
$my
);
sleep(1); // wait a bit
// test 2 - array_push($thread->array, 2);
$my->synchronized(
function($thread){
$thread->msg = 'test 2';
array_push($thread->array, 2);
$thread->notify();
},
$my
);
sleep(1); // wait a bit
// test 3 - array_push($thread->array, 2);
$my->synchronized(
function($thread){
$thread->msg = 'test 3';
$new = array(3);
$thread->array = array_merge($thread->array, $new);
$thread->notify();
},
$my
);
sleep(1); // wait a bit
$my->stop = true;
?>
out:
default
string(13) "default val 1"
string(13) "default val 2"
test 1
test 2
test 3
int(3)
so in this case only array_merge() worked.
