This function can only be used with buffered results attained from the use of the mysqli_store_result() or mysqli_query() functions.

Examples

Example 1482. Object oriented style

<?php
/* Open a connection */
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
   
printf("Connect failed: %s\n", mysqli_connect_error());
   exit();
}

$query = "SELECT Name, CountryCode FROM City ORDER BY Name";
if (
$result = $mysqli->query( $query)) {

   
/* seek to row no. 400 */
   
$result->data_seek(399);

   
/* fetch row */
   
$row = $result->fetch_row();

   
printf ("City: %s  Countrycode: %s\n", $row[0], $row[1]);

   
/* free result set*/
   
$result->close();
}

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


Example 1483. Procedural style

<?php
/* Open a connection */
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

/* check connection */
if (!$link) {
   
printf("Connect failed: %s\n", mysqli_connect_error());
   exit();
}

$query = "SELECT Name, CountryCode FROM City ORDER BY Name";

if (
$result = mysqli_query($link, $query)) {

   
/* seek to row no. 400 */
   
mysqli_data_seek($result, 399);

   
/* fetch row */
   
$row = mysqli_fetch_row($result);

   
printf ("City: %s  Countrycode: %s\n", $row[0], $row[1]);

   
/* free result set*/
   
mysqli_free_result($result);
}

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


The above example will output:

City: Benin City  Countrycode: NGA
