使用ussleep()调节cURL

Question

我正在使用web服务发送100的http帖子。但是，该服务每秒只允许5个。我想知道ussleep命令是否是执行此操作的最佳方法。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，但它应该为您提供了我要做的事情的想法(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++;
}
