getVar("SELECT name FROM users WHERE id = $user_id"); echo "Welcome, $user_name!"; ?>
getVar("SELECT COUNT(*) FROM users"); echo "There are $num_records users in the database."; ?>In this example, we use getVar() to retrieve the number of records in the "users" table. Package library: The database object used in these examples is not specified, so it is difficult to determine the package/library being used. However, getVar() is a common method in many PHP database libraries, including PDO, mysqli, and ADODB.
