Why is the "photo" array empty?

Question

PHP

$url = json_decode(file_get_contents("https://api.vk.com/method/photos.getMessagesUploadServer?access_token=".$this->token), true)["response"]["upload_url"]; 
$photo = __DIR__."/status1.jpg";
$post = ["photo" => curl_file_create($photo)]; 
$ch = curl_init($url);  
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data; charset=UTF-8')); 
$result = json_decode(curl_exec($ch), true); 
curl_close($ch);

Result: empty array photo[]

Pick in the direction of the file. Maybe there is no access, maybe there is no file. Works for me
