Examples of multithreaded operations implemented by PHP using Pthread

The examples in this article describe the multithreaded operations that PHP implements with Pthread. Share to everyone for your reference, as follows:

<?phpclass vote extends Thread {public $res = ';  Public $url = Array ();  Public $name = ';  Public $runing = false;  Public $LC = false;    Public function __construct ($name) {$this->res = ' temporarily none, first run. ';    $this->param = 0;    $this->lurl = 0;    $this->name = $name;    $this->runing = true;  $this-&GT;LC = false;        The public Function run () {$this->runing) {if ($this->param! = 0) {$nt = rand (1, 10);        echo "Thread [{$this->name}] received the task parameter: {$this->param}, {$nt} seconds to process the data. \ n";        $this->res = rand (100, 999);        Sleep ($NT);        $this->lurl = $this->param;      $this->param = "; } else {echo ' thread [{$this->name}] waits for the task:      \ n ";    } sleep (1); }}//Create a thread pool here. $pool [] = new vote (' a '), $pool [] = new vote (' B '), $pool [] = new vote (' C ');//start all threads so that they are in the working state of foreach ($pool as $w) {$w->start ();}  Dispatch task to thread for ($i = 1; $i < $i + +) {$worker _content = rand (10, 99); while (true) {   A foreach ($pool as $worker) {//parameter is NULL indicates that the thread is idle if ($worker->param== ") {$worker->param = $worker _co        ntent;        echo "[{$worker->name}] Thread is idle, put in parameter {$worker}, last parameter [{$worker->lurl}] result [{$worker->res}].\n];      Break 2;  }} sleep (1);    }}echo "All threads are dispatched, wait for execution to complete. \//wait for all threads to run end while (count ($pool)) {//Traverse check thread group run end foreach ($pool as $key = = $threads) {      if ($worker->param== ") {echo" [{$threads->name}] Thread is idle, last parameter [{$threads->lurl}] result [{$threads->res}].\n];      echo "[{$threads->name}] thread run complete, exit. \ n";      Set End flag $threads->runing = false;    Unset ($pool [$key]);  }} echo "Waiting ... \ n"; Sleep (1);} echo "All threads have finished executing. \ n";
