$_files says there is
$_files[''myfile''][''name''] The original name of the client file.
$_files[''myfile''][''type''] The mime type of the file, which requires the browser to provide support for this information, such as "image/gif".
$_files[''myfile''][''size''] The size of the uploaded file, in bytes.
$_files[''myfile''][''tmp_name''] The temporary file name stored on the server after the file is uploaded, usually the system default. It can be specified in upload_tmp_dir in php.ini, but setting it with the putenv() function has no effect.
$_files[''myfile''][''error''] Error code related to the file upload. [''error''] was added in PHP 4.2.0 version
