Неустранимая ошибка: допустимый размер памяти 33554432 байт исчерпан (пытался выделить 12288 байт).
Это ошибка, которую я получаю, когда пытаюсь загрузить изображение примерно на 2,94 мб.
Когда я загружаю изображение на 100 кб, и поэтому он отлично работает. Почему это?
Как я могу сделать ограничение, поэтому, если вы загружаете байты xx, вы получите ошибку, которая слишком велика, поэтому я не получаю эту фатальную ошибку.
я начал делать это в форме
