You'd better check $_FILES structure and values throughly.
The following code cannot cause any errors absolutely.

Example:
<?php

header

('Content-Type: text/plain; charset=utf-8');

try {

// Undefined | Multiple Files | $_FILES Corruption Attack
    // If this request falls under any of them, treat it invalid.
   
if (
        !isset(
$_FILES['upfile']['error']) ||
       
is_array($_FILES['upfile']['error'])
    ) {
        throw new
RuntimeException('Invalid parameters.');
    }
// Check $_FILES['upfile']['error'] value.
   
switch ($_FILES['upfile']['error']) {
        case
UPLOAD_ERR_OK:
            break;
        case
UPLOAD_ERR_NO_FILE:
            throw new
RuntimeException('No file sent.');
        case
UPLOAD_ERR_INI_SIZE:
        case
UPLOAD_ERR_FORM_SIZE:
            throw new
RuntimeException('Exceeded filesize limit.');
        default:
            throw new
RuntimeException('Unknown errors.');
    }
// You should also check filesize here.
   
if ($_FILES['upfile']['size'] > 1000000) {
        throw new
RuntimeException('Exceeded filesize limit.');
    }
// DO NOT TRUST $_FILES['upfile']['mime'] VALUE !!
    // Check MIME Type by yourself.
   
$finfo = new finfo(FILEINFO_MIME_TYPE);
    if (
false === $ext = array_search(
       
$finfo->file($_FILES['upfile']['tmp_name']),
        array(
           
'jpg' => 'image/jpeg',
           
'png' => 'image/png',
           
'gif' => 'image/gif',
        ),
       
true
   
)) {
        throw new
RuntimeException('Invalid file format.');
    }
// You should name it uniquely.
    // DO NOT USE $_FILES['upfile']['name'] WITHOUT ANY VALIDATION !!
    // On this example, obtain safe unique name from its binary data.
   
if (!move_uploaded_file(
       
$_FILES['upfile']['tmp_name'],
       
sprintf('./uploads/%s.%s',
           
sha1_file($_FILES['upfile']['tmp_name']),

IE on the Mac is a bit troublesome.  If you are uploading a file with an unknown file suffix, IE uploads the file with a mime type of "application/x-macbinary".  The resulting file includes the resource fork wrapped around the file.  Not terribly useful.

The following code assumes that the mime type is in $type, and that you have loaded the file's contents into $content.  If the file is in MacBinary format, it delves into the resource fork header, gets the length of the data fork (bytes 83-86) and uses that to get rid of the resource fork.

(There is probably a better way to do it, but this solved my problem):

<?php
if ($type == 'application/x-macbinary') {
    if (
strlen($content) < 128) die('File too small');
   
$length = 0;
    for (
$i=83; $i<=86; $i++) {
       
$length = ($length * 256) + ord(substr($content,$i,1));
          }
   
$content = substr($content,128,$length);
}
?>

Your binary files may be uploaded incorrectly if you use modules what recode characters. For example, for Russian Apache, you should use
<Files ScriptThatReceivesUploads.php>
CharsetDisable On
</Files>

IE on the Mac is a bit troublesome.  If you are uploading a file with an unknown file suffix, IE uploads the file with a mime type of "application/x-macbinary".  The resulting file includes the resource fork wrapped around the file.  Not terribly useful. 1

Làm cách nào để xem các tệp đã tải lên trong PHP?

Trong PHP, chúng ta có thể truy cập tên thực tế của tệp mà chúng ta đang tải lên bởi từ khóa $ _FILES [Tệp File] [Tên Tên]. $ _Files là từ khóa mặc định trong PHP để truy cập các chi tiết của các tệp mà chúng tôi đã tải lên. Tệp đề cập đến tên được xác định trong chỉ mục trên mạng. Hình thức HTML trong đầu vào của tệp.by keyword $_FILES[“file”][“name”]. The $_FILES is the by default keyword in PHP to access the details of files that we uploaded. The file refers to the name which is defined in the “index. html” form in the input of the file.

PHP sử dụng vị trí nào làm mặc định khi các tệp ban đầu được tải lên?

Các tệp được tải lên trước tiên được lưu trữ trong một thư mục tạm thời (đừng lo lắng, tập lệnh PHP của bạn có thể di chuyển các tệp đến một vị trí lâu dài hơn sau đó). Theo mặc định, vị trí ban đầu là thư mục tạm thời mặc định của hệ thống. Bạn có thể chỉ định một thư mục khác bằng cách sử dụng Chỉ thị Upload_TMP_DIR trong PHP.the system's default temporary directory. You can specify a different directory using the upload_tmp_dir directive in php.

Chức năng PHP nào được sử dụng để tải lên các tệp?

Enctype = "Multipart/Form-data": Giá trị này đề cập đến loại nội dung của các tệp sẽ được chấp nhận để tải lên.Nó cũng chỉ ra loại mã hóa mà tập lệnh PHP sẽ sử dụng để tải lên.Giá trị dữ liệu đa dạng/hình thức cho phép chúng tôi tải lên các tệp bằng phương thức POST.

Làm cách nào để tìm các tệp đã tải lên của tôi trong HTML?

Làm cách nào để hiển thị tệp được tải lên trong HTML bằng JavaScript ?..
Var uploadedfile = Hồi giáo;file.AdDeventListener ('Change', function () {const reader = new filereader () ;.
reader.AdDeventElistener ('load', function () {uploadedFile = reader.Result; ....
reader.ReadDataurl (this.files [0]);}).
