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 ($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 #2 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
