Can anyone give me an example for PHP's CURLFile class?

Question

I had a very simple PHP code to upload a file to a remote server; the way I was doing it (as has been suggested here in some other solutions) is to use cUrl to upload the fi

CURLFile has been explained well above, but for simple one file transfers where you don't want to send a multipart message (not needed for one file, and some APIs don't support multipart), then the following works.

$ch = curl_init('https://example.com');

$verbose = fopen('/tmp/curloutput.log', 'w+'); // Not for production, but useful for debugging curl issues.

$filetocurl = fopen(realpath($filename), 'r');

// Input the filetocurl via fopen, because CURLOPT_POSTFIELDS created multipart which some apis do not accept.

// Change the options as needed.

$options = array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => array(
        'Content-type: application/whatever_you_need_here',
        'Authorization: Basic ' . $username . ":" . $password) // Use this if you need password login
    ),
    CURLOPT_NOPROGRESS => false,
    CURLOPT_UPLOAD => 1,
    CURLOPT_TIMEOUT => 3600,
    CURLOPT_INFILE => $filetocurl,
    CURLOPT_INFILESIZE => filesize($filename),
    CURLOPT_VERBOSE => true,
    CURLOPT_STDERR => $verbose  // Remove this for production
);

if (curl_setopt_array($ch, $options) !== false) {
    $result = curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
} else {
    // A Curl option could not be set. Set exception here
}

Note the above code has some extra debug - remove them once it is working.
