extract() not working

Does someone see a reason why extract() in line 7 below shouldn't work.  The database access is working because I can see in line 6 that the timestamp at $row[0] is correct and the firstName at $row[1] is correct. But extract($row) doesn't create the variables $timestamp and $firstName.

Thanks for any insight.

        $db = db_connect();
	$query = "SELECT timestamp, firstName FROM sales WHERE transactionID = '$transactionID'";
	$result = mysqli_query($db, $query)
		or die ("Couldn't execute query");  
	$row = mysqli_fetch_row($result);	
	echo "\$row[0] = $row[0], \$row[1] = $row[1]";
	extract($row);
	echo "\$timestamp is $timestamp \$firstName is $firstName";

Per PHP extract, you cannot use a numerically-indexed array: "a numerically indexed array will not produce results unless you use EXTR_PREFIX_ALL or EXTR_PREFIX_INVALID."

So pass EXTR_PREFIX_ALL as the second argument to extract.

Ah! Yes.  I was using mysqli_fetch_row() to get the query results, which returns an enumerated array, which extract() doesn't work on,  unless you include your own prefix.  .I should have used mysqli_fetch_assoc(), which brings back an associative array, which extract() does work on.

Thanks.
