使用usleep()调节cURL

Question

我正在使用一个网络服务来发送100个http帖子。然而，该服务仅允许每秒5个。我想知道usleep命令是否是实现此目的的最佳方法。例如：

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

Answer 1

现在这是未经测试的，但它应该为您提供我会做什么的想法(也许这段代码就是这样工作的-谁知道呢……)：

// 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++;
}
