Information in the phpinfo.php page describes the temporary directory that is used for file uploads as upload_tmp_dir and the maximum permitted size of files that can be uploaded is stated as upload_max_filesize. These parameters are set into PHP configuration file php.ini

The user clicks the browse button and selects a file to upload from the local PC.
The full path to the selected file appears in the text filed then the user clicks the submit button.
The selected file is sent to the temporary directory on the server.
The PHP script that was specified as the form handler in the form's action attribute checks that the file has arrived and then copies the file into an intended directory.
The PHP script confirms the success to the user.

$_FILES['file']['name'] − the actual name of the uploaded file.
$_FILES['file']['size'] − the size in bytes of the uploaded file.
$_FILES['file']['type'] − the MIME type of the uploaded file.
$_FILES['file']['error'] − the error code associated with this file upload.
