How to send a photo on behalf of a bot?

Question

PHP

Hello everyone, there is a code for uploading photos to the VK server:

$par = array(
    'access_token' => '///',
    'peer_id' => 424401660,
    'v' => 5.103
);
        
$user = json_decode(file_get_contents('https://api.vk.com/method/photos.getMessagesUploadServer?' . urldecode(http_build_query($par))), true);
$curl_file = curl_file_create("./photos/send/",'image/jpeg','1583856373.jpg');
$ch=curl_init();
curl_setopt_array($ch, 
  array(
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_URL => $user['response']['upload_url'],
    CURLOPT_POST => 1,
    CURLOPT_POSTFIELDS => array("photo" => $curl_file)
  ));

$img_attach = json_decode(curl_exec($ch), true);

print_r($img_attach);

But when the answer is displayed, it does not display anything! What could be the problem?
Thanks in advance

You are using curl_file_create() incorrectly. The first parameter is to pass the path to the file.

curl_file_create ( string $filename [, string $mimetype [, string $postname ]] ) : CURLFile
