Я создал форму, которая собирает данные о клиентах. Эти данные отправляются в базу данных MySQL, а изображения перемещаются в требуемую папку на моем сервере.
То, что я пытаюсь выполнить, – это разрешить загрузку изображений. Когда у меня есть критерии, установленные для GIF, он работает хорошо, но когда я пытаюсь использовать JPG / JPEG / PNG, он не работает.

Вместо того, чтобы пытаться определить тип файла по расширению, вы должны открыть файл и посмотреть, что в нем.
$allowed_types = array(IMAGETYPE_GIF,IMAGETYPE_JPEG,IMAGETYPE_PNG); if (in_array(exif_imagetype($_FILES["upload_picture"]["tmp_name"]), $allowed_types)){ //is either jpeg, png or gif }
