## Examples

Example 1. Object oriented style
`<?php $mysqli = new mysqli("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; /* 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); ?>`

The above example will output:
