Examples
Example 20.148. 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(); } $query = 'SELECT Name, CountryCode FROM City ORDER BY Name'; if ($stmt = $mysqli->prepare($query)) { /* execute query */ $stmt->execute(); /* bind result variables */ $stmt->bind_result($name, $code); /* store result */ $stmt->store_result(); /* seek to row no. 400 */ $stmt->data_seek(399); /* fetch values */ $stmt->fetch(); printf ('City: %s Countrycode: %s\n', $name, $code); /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?>
Example 20.149. Procedural style
<?php /* Open a connection */ $link = mysqli_connect('localhost', 'my_user', 'my_password', 'world'); /* check connection */ if (mysqli_connect_errno()) { printf('Connect failed: %s\n', mysqli_connect_error()); exit(); } $query = 'SELECT Name, CountryCode FROM City ORDER BY Name'; if ($stmt = mysqli_prepare($link, $query)) { /* execute query */ mysqli_stmt_execute($stmt); /* bind result variables */ mysqli_stmt_bind_result($stmt, $name, $code); /* store result */ mysqli_stmt_store_result($stmt); /* seek to row no. 400 */ mysqli_stmt_data_seek($stmt, 399); /* fetch values */ mysqli_stmt_fetch($stmt); printf ('City: %s Countrycode: %s\n', $name, $code); /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>
The above examples will output:
City: Benin City Countrycode: NGA
