V. Installation of Pthreads expansion

Copy Php_pthreads.dll to the directory bin\php\ext\ below.
Copy PthreadVC2.dll to the directory bin\php\ below.
Copy PthreadVC2.dll to the directory C:\windows\system32 below.
Open the PHP configuration file php.ini. Plus Extension=php_pthreads.dll in the back.
Tips! The Windows system needs to add the path where the PthreadVC2.dll resides to the PATH environment variable. My Computer---> right mouse button---> Properties---> Advanced---> Environment variables---> System variables---> Find the name path---> Edit---> After the value of the variable plus the full path of the PthreadVC2.dll (my C:\WINDOWS\system32\pthreadVC2.dll).

Six, add thread class

 <?php class Thread {var $hooks = array ();
  var $args = array ();
    function thread () {} function Addthread ($func) {$args = Array_slice (Func_get_args (), 1);
    $this->hooks[] = $func;
    $this->args[] = $args;
  return true;
    function Runthread () {if (Isset ($_get[' flag ')) {$flag = intval ($_get[' flag ']);
    } if ($flag | | $flag = = 0) {call_user_func_array ($this->hooks[$flag], $this->args[$flag]); else {for ($i = 0, $size = count ($this->hooks); $i < $size; $i + +) {$fp =fsockopen ($_se
        rver[' http_host '],$_server[' server_port ']);
          if ($fp) {$out = "get {$_server[' php_self ']}?flag= $i http/1.1rn";
          $out. = "Host: {$_server[' http_host ']}rn";
          $out. = "Connection:closernrn";
          Fputs ($fp, $out);
        Fclose ($FP); }
      }
    }
  }
}

Vii. Test pthreads Extension

Include (' thread.php ');
Class AsyncOperation extends Thread {public
  function __construct ($arg) {
    $this->arg = $arg;
  }
  Public Function Run () {
    if ($this->arg) {
      printf ("Hello%s\n", $this->arg);
    }
} $thread = new AsyncOperation ("World");
if ($thread->start ())
  $thread->join ();
