Example #1 Object oriented style

/* check connection */

if (mysqli_connect_errno()) {

    printf("Connect failed: %s\n", mysqli_connect_error());

    exit();

}



/* determine our thread id */

$thread_id = $mysqli->thread_id;



/* Kill connection */

$mysqli->kill($thread_id);



/* This should produce an error */

if (!$mysqli->query("CREATE TABLE myCity LIKE City")) {

    printf("Error: %s\n", $mysqli->error);

    exit;

}



/* close connection */

$mysqli->close();

?>

Example #2 Procedural style


<?php

$link = mysqli_connect("localhost", "my_user", "my_password", "world");



/* check connection */

if (mysqli_connect_errno()) {

    printf("Connect failed: %s\n", mysqli_connect_error());

    exit();

}



/* determine our thread id */

$thread_id = mysqli_thread_id($link);



/* Kill connection */

mysqli_kill($link, $thread_id);



/* This should produce an error */

if (!mysqli_query($link, "CREATE TABLE myCity LIKE City")) {

    printf("Error: %s\n", mysqli_error($link));

    exit;

}



/* close connection */

mysqli_close($link);

?>
