PHP 8.1.28 Released!

The Worker class

(PECL pthreads >= 2.0.0)

Giriş

Worker Threads have a persistent context, as such should be used over Threads in most cases.

When a Worker is started, the run method will be executed, but the Thread will not leave until one of the following conditions are met:

  • the Worker goes out of scope (no more references remain)

  • the programmer calls shutdown

  • the script dies

This means the programmer can reuse the context throughout execution; placing objects on the stack of the Worker will cause the Worker to execute the stacked objects run method.

Sınıf Sözdizimi

class Worker extends Thread implements Traversable, Countable, ArrayAccess {
/* Yöntemler */
public collect(Callable $collector = ?): int
public getStacked(): int
public isShutdown(): bool
public shutdown(): bool
public stack(Threaded &$work): int
public unstack(): int
/* Miras alınan yöntemler */
public Thread::join(): bool
public Thread::start(int $options = ?): bool
}

There's one way to shared datas between Workers, that is using Stackable:
<?php
class data extends Stackable{
//private $name;
public function __construct($_name) {
//$this->name = $_name;//if you set any variable, workers will get the variable, so do not set any variable
echo __FILE__.'-'.__LINE__.'<br/>'.chr(10);
}
public function
run(){
echo
__FILE__.'-'.__LINE__.'<br/>'.chr(10);
}
}
class
readWorker extends Worker {
public function
__construct(&$_data) {
$this->data = $_data;//
}
public function
run(){
while(
1){
if(
$arr=$this->data->shift())//receiving datas
{
echo
'Received data:'.print_r($arr,1).chr(10);
}else
usleep(50000);
}
}
}
class
writeWorker extends Worker {
public function
__construct(&$_data) {
$this->data = $_data;//
}
public function
run(){
while(
1){
$this->data[] = array(time(),rand());//writting datas
usleep(rand(50000, 1000000));
}
}

}
$data = new data('');
$reader = new readWorker($data);
$writer = new writeWorker($data);
$reader->start();
$writer->start();
?>
Also you can use $readWorker[] = $some_data; then use $this->shift() in readWorker to share datas with readWorker, but if you do so you can't have variables in readWorker as all variales will be shift by shift();
