php – 使用usleep()节流cURL

我正在使用网络服务发送100个http帖子.但是,该服务仅允许每秒5次.我想知道usleep命令是否是最好的方法.例如:

foreach($JSONarray['DATABASE'] as $E) 
{
    $aws = curl_init();
    //curl stuff
    curl_exec($aws);
    curl_close($aws);
    usleep(200000);
}

最佳答案 现在这是未经测试的,但它应该为您提供我将要做的事情的想法(也许这个片段就像它一样工作 – 谁知道……):

// presets
$thissecond = time();
$cnt = 0;

foreach($JSONarray['DATABASE'] as $E) 
{
  while ($thissecond == time() && $cnt > 4) { // go into "waiting" when we going to fast
    usleep(100000); // wait .1 second and ask again
  }

  if ($thissecond != time()) { // remember to reset this second and the cnt
    $thissecond = time();
    $cnt = 0;
  }

  // off with the payload
  $aws = curl_init();
  //curl stuf
  curl_exec($aws);
  curl_close($aws);

  // remember to count it all
  $cnt++;
}
