file uploading error

[Minkhant029814]

From manual page: https://php.net/function.move-uploaded-file

--- when I upload the file, it goes to the destination directory but there is still some warning error.
d: move_uploaded_file(): Passing null to parameter #1 ($from) of type string is deprecated in C:\wamp64\www\Projects\phpProject\72\form_handling_file.php on line;

This my code;

This feels more like a support request. While the example doesn't include error handling or much logic (e.g., it does not confirm that a variable exists before using it), that goes beyond the scope of all examples.

Closing this in the meantime, please reopen if you disagree or can describe a more specific problem or feature request.
