PHP cURL required only to send and not wait for response

Question

I need a PHP cURL configuration so that my script is able to send requests and ignore the answers sent by the API.

curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_POST,count($fields)); curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string); // curl_setopt($ch, CURLOPT_RETURNTRANSFER, false); //curl_setopt($ch, CURLOPT_TIMEOUT_MS, 100); $result = curl_exec($ch); echo $result; curl_close ($ch); 

I tried adding: // curl_setopt($ch, CURLOPT_RETURNTRANSFER, false); //curl_setopt($ch, CURLOPT_TIMEOUT_MS, 100);

But its not working properly and the API webserver is not receiving the requests.

The reason for this is I am sending large amount of requests to the API therefore my script is very slow because it waits for each and every request.

Any help is appreciated.

Sender file example ./ajax/sender.php

Below we trying just make ping to php script without waiting on answer

    $url = 'https://127.0.0.1/ajax/received.php';     $curl = curl_init();                     $post['test'] = 'examples daata'; // our data todo in received     curl_setopt($curl, CURLOPT_URL, $url);     curl_setopt ($curl, CURLOPT_POST, TRUE);     curl_setopt ($curl, CURLOPT_POSTFIELDS, $post);           curl_setopt($curl, CURLOPT_USERAGENT, 'api');      //curl_setopt($curl, CURLOPT_TIMEOUT, 1); //if your connect is longer than 1s it lose data in POST better is finish script in recevie     curl_setopt($curl, CURLOPT_HEADER, 0);     curl_setopt($curl,  CURLOPT_RETURNTRANSFER, false);     curl_setopt($curl, CURLOPT_FORBID_REUSE, true);     curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 1);     curl_setopt($curl, CURLOPT_DNS_CACHE_TIMEOUT, 10);           curl_setopt($curl, CURLOPT_FRESH_CONNECT, true);          curl_exec($curl);             curl_close($curl);   

Received file example ./ajax/received.php

EDIT 2019 if you using fastcgi just finish fastcgi and browser close connection but script still will be working up to end.

How finish script: PHP mod_fcgi with fastcgi_finish_request();

For Apache2:

ob_end_flush(); flush(); 

For php-fpm

fastcgi_finish_request(); $this->db->query('UPDATE new_hook_memory SET new=new+1 WHERE id=1'); 

Old version:

ob_end_clean(); //if our framework have turn on ob_start() we don't need bufering respond up to this script will be finish      header("Connection: close\r\n"); //send information to curl is close     header("Content-Encoding: none\r\n"); //extra information      header("Content-Length: 1"); //extra information     ignore_user_abort(true); //script will be exisits up to finish below query even web browser will be close before sender get respond      //we doing here what we would like do     $this->db->query('UPDATE new_hook_memory SET new=new+1 WHERE id=1');
