php cURL post data to remote server not working

Question

I'm trying to send data via cURL post but I've never tried it before and I don't know if I'm doing it right.

What I want to do is sent a file via post to a file from my remote server and there read the file and insert data into database but unfortunately it's not working and error_log doesn't show me anything.

My code looks like this:

$ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,"https://".$host."/file.php");
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, array(
            'file' => '@'.realpath(../path/to/file/'.$_POST['file_name'].'.txt'),
            'action' => 'first',
            'check' => $_POST['file_name'],
        ));
        $result = curl_exec($ch);
        curl_close($ch);

This code is placed after some sql querys and code made to write this sql results into the file that I'm trying to send.

What do your receive from the server? Just print the $result variable. Also, you can read the HTTP status code $responseCode = curl_getinfo($ch, CURLINFO_RESPONSE_CODE); before you close the connection. Or try without uploading the file — Ruben

An issue occurs because CURLOPT_POSTFIELDS is supposed to be http_build_query($array), not an array. php.net/manual/ro/function.http-build-query.php — Cat

@Ruben it's the first time I'm using cURL and I don't understand how it really works. What my code is doing is putting that information via post in the CURLOPT_URL, right? Or is it getting that information via post from that url? Cause I'm understanding it like the first case. — molinet

Is there a missing quote in .realpath(../path/to/file/'.$_POST['file_name'].'.txt') - should there be one before ../path — Nigel Ren
