How to send file with cURL exec PHP

Question

I have this application where from a web page the user uploads a file, what i need to do is that the application sends this file to another API.

Now i don't care what happens or what response i get after doing the cURL request because it takes too long to process. i only notify the user that his/her file was uploaded correctly.

my code:

 curl_setopt_array( $ch, [ CURLOPT_VERBOSE=>true, CURLOPT_RETURNTRANSFER => true, CURLOPT_URL => $this->endpoint, CURLOPT_POSTFIELDS => $this->payload, ] ); curl_exec($ch);

$this->endpoint contains the url and $this->payload the file received. From the API i sent that file i get the message that no file was sent or the file is in a incorrect format. My guess is that i'm not sending the file correctly when executing the command. How to i can send that file?

@НиколайЛубышев I already read that, the file itself it's not on the server but received from another web request — Progs

Why don't you use the built-in curl functions of PHP? You can't use curl_getinfo() with exec(). — Barmar

Content-Type: application/json ? file bypass with "Content-Type: octet/stream" its first Second? try save file and after that send it. Next step send from memory be stream php-functions, AND DO NOT exec() )))) — Николай Лубышев

Your explanation of why you're doing it this way doesn't make sense. You're not running the command in the background, so exec() waits for the response. — Barmar

Use the built-in curl functions.

$ch = curl_init($this->endpoint); curl_setopt_array($ch, [ CURLOPT_POST => true, CURLOPT_POSTFIELDS => json_encode($this->payload), CURLOPT_HTTPHEADER => [ "Content-type: application/json", "Accept: application/json" ] ]); if (curl_exec($ch)) { return [ 'code' => 200, 'success' => True, 'message' => curl_getinfo($cmd), ]; } else { return [ 'code' => curl_getinfo($ch, CURLINFO_RESPONSE_CODE), 'success' => false, 'message' => "Curl failed" ]; }

that will wait until the entire upload is complete before returning. this guy probably needs fastcgi_finish_request()
