Database interface code for MySQL database servers using the mysqli client libraries. mysqli is included in PHP 5 by default and allows developers to use the advanced features of MySQL 4.1.x, 5.0.x and beyond.

Code

function db_result($result) {
  if ($result && mysqli_num_rows($result) > 0) {
    // The mysqli_fetch_row function has an optional second parameter $row
    // but that can't be used for compatibility with Oracle, DB2, etc.
    $array = mysqli_fetch_row($result);
    return $array[0];
  }
  return FALSE;
}
