I sent 50-100 requests to my API at one time with curl, but I got this error :"This object cannot be accessed right now because another API request process is currently accessing it." So I really need to wait for the response of the recently request then execute the next request. How can I do that?
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'site');
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('$header'));
curl_setopt($ch, CURLOPT_POSTFIELDS, '$postfield');
$result = curl_exec($ch);
