Good day!
Enough of this safe way to upload images to the server?
upload.php

$AllowFileExtension = array(
'jpg',
'png',
'jpeg'
);
$FileExtension = pathinfo(strtolower($_FILES['file']['name'][0]), PATHINFO_EXTENSION);
if (!in_array($FileExtension, $AllowFileExtension)) {
die('Allowed file formats: jpg, jpeg, png.')...
