<?php
$link = mysqli_connect("localhost", "user", "password", "database");
$query = "SELECT * FROM table";
$result = mysqli_query($link, $query);
$row = mysqli_fetch_array($result, MYSQLI_BOTH); # failed
printf ("1. %s (%s)\n", $row[0], $row['name']);
#$row = mysqli_fetch_array($result, MYSQLI_NUM); # failed
#printf ("2. %s (%s)\n", $row[0], $row[0]);
#$row = mysqli_fetch_array($result, MYSQLI_ASSOC); # failed
#printf ("3. %s (%s)\n", $row[0], $row['name']);
#$row = mysqli_fetch_array($result); # ok
#printf ("4. %s (%s)\n", $row[0], $row[0]);
?>

A row like this:
1. 2 (Hello World)
