In this article, we will focus on the mysqli_kill() function in PHP, which is used to terminate a MySQL client connection. We will provide you with an overview of the function, how it works, and examples of its use.

Introduction to the mysqli_kill() function

The mysqli_kill() function is a built-in function in PHP that is used to terminate a MySQL client connection. This function is useful when you need to forcefully terminate a MySQL connection due to unexpected behavior or security concerns.

How to use the mysqli_kill() function

Using the mysqli_kill() function is very simple. You just need to call the function on a valid MySQLi connection with a specific connection ID. Here is an example:

$mysqli = mysqli_connect("localhost", "username", "password", "database");

$connection_id = mysqli_thread_id($mysqli);

mysqli_kill($mysqli, $connection_id);


In this example, we call the mysqli_connect() function to connect to a MySQL database with a username and password. We then get the ID of the current MySQLi connection using the mysqli_thread_id() function. We then call the mysqli_kill() function on the MySQLi connection to terminate the connection with the specific ID. We then close the MySQLi connection using the mysqli_close() function.


In conclusion, the mysqli_kill() function is a useful tool for terminating a MySQL client connection with a specific ID. By understanding how to use the function, you can take advantage of this feature to create powerful and secure MySQLi queries.
