If you need to get a specific value from a query, like
SELECT COUNT(name) FROM Customers, in PHP, use
customer_count = pg_fetch_result($result, 0, 0)The first zero specifies the row, starting at 0, and the second zero specifies which column.
$_SERVER['DOCUMENT_ROOT']in PHP returns /cs425/public_html
If you want to have the api redirect a client using the Location header, the server must have the response status code as 302, even with Location set, it won't redirect with a 200 code.
