Загрузка файлов не работает для больших файлов

Я пытаюсь загрузить .zip-файл. Он хорошо работает для небольших файлов. Но я могу загрузить файлы> 2 МБ. Когда я пытаюсь загрузить файлы> 2 MB google chrome показывает в нижнем левом углу как (uploadin: -%), где – не нравится 10. Но он застревает после 14%. Через некоторое время появляется сообщение об ошибке «Ошибка 101 (net :: ERR_CONNECTION_RESET): соединение было сброшено». Эта веб-страница недоступна.

пожалуйста, помогите мне

• Безопасная загрузка файлов и их проверка
• Ошибка загрузки файла PHP
• Каков наилучший способ загрузки и хранения изображений на сайте?
• Выполнять запросы и обрабатывать ответы для возобновляемой загрузки: Google Drive api
• Загрузка файла PHP: подтверждение на mime или расширение?

Это код формы

И я хотел бы загрузить> 3MB-файлы в поле .zip, показанное ниже

 <div class="right"><input type="file" name="itemfile" id="itemfile" class="input" /> <em>.ZIP File Only </em> </div> 

 ; Maximum allowed size for uploaded files. upload_max_filesize = 2M 

 upload_max_filesize = Required_size M 

 echo ini_get('max_input_time');
