Exemplo 1. Object oriented style

Exemplo 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); ?>`

O exemplo acima irá imprimir:

    City: Benin City  Countrycode: NGA
