Examples
Example #1 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 #2 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 examples will output:
City: Benin City Countrycode: NGA
