I believe you're mixing your T-SQL with your PHP. Sort of like getting
chocolate in your peanut butter, but not half as delicious.

CONCAT_WS is a MySQL server-side function. It cannot be called
directly from PHP, but rather via a database call performed **by**

Also--PHP has the nifty "dot" (.) operator for concatenating strings. Try this:

$Author = $f_nameIN . ' ' . $l_nameIN;
echo $Author;
