myupload.php handles the uploaded file. In PHP, posted files can be accessed
via the $_FILES array. This array in turn has an array with the following entries:
-
$_FILES["userfile"]["name"]The original name of the file on the client machine. -
$_FILES['userfile']['type']
The mime type of the file, if the browser provided this information. An example would be "image/gif". -
$_FILES['userfile']['size']
The size, in bytes, of the uploaded file. -
$_FILES['userfile']['tmp_name']
The temporary filename of the file in which the uploaded file was stored on the server.
When a posted file is retrieved, PHP automatically saves the file in a temporary
directory. We copy the
file to a permanent location using the move_uploaded_file() function,
which simply takes the temporary file name (accessed by 'tmp_name') and the
location to move it to.
