PHP allows you to upload single and multiple files on remote server using a Simple HTML form. You can upload any kind of file like images, videos, ZIP files, PDFs, as well as executables files.
$_FILES['file']
contains the information about the uploaded file. Each of these per-file arrays has five elements:
$_FILES['file']['name']
: The name of the uploaded file. This is supplied by the browser so it could be a full pathname or just a filename.$_FILES['file']['type']
: The MIME type of the file, as supplied by the browser.$_FILES['file']['size']
: The size of the file in bytes, as calculated by the server.$_FILES['file']['tmp_name']
: The location in which the file is temporarily stored on the server.$_FILES['file']['error']
: An error code returns what (if anything) went wrong with the file upload.
