	      <?php
	      /* Open a connection */

		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      $query = "SELECT name, zip FROM hotel.city ORDER BY name";
	      if ($stmt = $maxdb->prepare($query)) {

		 /* execute query */
		 $stmt->execute();

		 /* bind result variables */
		 $stmt->bind_result($name, $code);

		 /* store result */
		 $stmt->store_result();

		 /* seek to row no. 5 */
		 $stmt->data_seek(5);

		 /* fetch values */
		 $stmt->fetch();

		 printf ("City: %s  Zip: %s
", $name, $code);

		 /* close statement */
		 $stmt->close();
	      }

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      /* Open a connection */
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      $query = "SELECT name, zip FROM hotel.city ORDER BY name";
	      if ($stmt = maxdb_prepare($link, $query)) {

		 /* execute query */
		 maxdb_stmt_execute($stmt);

		 /* bind result variables */
		 maxdb_stmt_bind_result($stmt, $name, $code);

		 /* store result */
		 maxdb_stmt_store_result($stmt);

		 /* seek to row no. 5 */
		 maxdb_stmt_data_seek($stmt, 5);

		 /* fetch values */
		 maxdb_stmt_fetch($stmt);

		 printf ("City: %s  Zip: %s
", $name, $code);

		 /* close statement */
		 maxdb_stmt_close($stmt);
	      }

	      /* close connection */
	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       City: Dallas  Zip: 75243
