2、给出一段PHP多线程、与For循环，抓取百度搜索页面的PHP代码示例：
<?php
  class test_thread_run extends Thread
  {
      public $url;
      public $data;
      public function __construct($url)
      {
          $this->url = $url;
      }
      public function run()
      {
          if(($url = $this->url))
          {
              $this->data = model_http_curl_get($url);
          }
      }
  }
  function model_thread_result_get($urls_array)
  {
      foreach ($urls_array as $key => $value)
      {
          $thread_array[$key] = new test_thread_run($value["url"]);
          $thread_array[$key]->start();
      }
      foreach ($thread_array as $thread_array_key => $thread_array_value)
      {
          while($thread_array[$thread_array_key]->isRunning())
          {
              usleep(10);
          }
          if($thread_array[$thread_array_key]->join())
          {
              $variable_data[$thread_array_key] = $thread_array[$thread_array_key]->data;
          }
      }
      return $variable_data;
  }
  function model_http_curl_get($url,$userAgent="")
  {
      $userAgent = $userAgent ? $userAgent : 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)';
      $curl = curl_init();
      curl_setopt($curl, CURLOPT_URL, $url);
      curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($curl, CURLOPT_TIMEOUT, 5);
      curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
      $result = curl_exec($curl);
      curl_close($curl);
      return $result;
  }
  for ($i=0; $i < 100; $i++)
  {
      $urls_array[] = array("name" => "baidu", "url" => "http://www.baidu.com/s?wd=".mt_rand(10000,20000));
  }
  $t = microtime(true);
  $result = model_thread_result_get($urls_array);
  $e = microtime(true);
  echo "多线程：".($e-$t)."\n";
  $t = microtime(true);
  foreach ($urls_array as $key => $value)
  {
      $result_new[$key] = model_http_curl_get($value["url"]);
  }
  $e = microtime(true);
  echo "For循环：".($e-$t)."\n";
?>
以上就介绍了PHP 真正多线程的使用，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
