Вызов CURL не загружает файл с локального на удаленный сервер Переполнение стека

Попробуйте следующий код, я обновил его в соответствии с вашими потребностями. Также, когда мы публикуем файл, он не будет отображаться с помощью $_POST как вы делаете, вместо этого, чтобы увидеть файлы, которые нужно распечатать $_FILES

Я не проверял ваш код, но мне кажется, это нормально. Ваша главная ошибка в том, что вы печатаете файл загрузки, используя $_POST, Загрузка файлов доступна в $_FILES массив. Попробуйте напечатать это.

Загрузить файл: (Это совместимо даже с более старыми версиями PHP)
Обратите внимание, что в целях совместимости, когда CURLFile недоступен (для PHP менее 5.5), я использовал file_get_contents.

Загрузка загрузки:

<?php
print_r($_POST); //this will print post varibales expect file types
print_r($_FILES); // this will print files that are posted
