you forget second parameter of myslqi_fetch_array() function. in second parameter telling type of array want return.

// numeric array $row=mysqli_fetch_array($result,mysqli_num); printf ("%s (%s)\n",$row[0],$row[1]);  // associative array $row=mysqli_fetch_array($result,mysqli_assoc); printf ("%s (%s)\n",$row["lastname"],$row["age"]);
