Trouble understing code
Here is the code that i got from "Beginning PHP5,Apache, MySQL. Web Development" book.
$query_d = "SELECT people_fullname FROM people WHERE people_id = '$movie_director'";
$results_d = mysql_query($query_d)
$row_d = mysql_fetch_array($results_d);
$director = $people_fullname;
My question are where did $people_fullname's value come from and if the value is from "extract($row_d), then how did $people_fullname get the value from "extract($row) ?
