mysqli::$thread_id - Returns the thread ID for the current connection

       Object oriented style

SYNOPSIS
int$mysqli->thread_id () DESCRIPTION
Procedural style int mysqli_thread_id (mysqli $link) The mysqli_thread_id(3) function returns the thread ID for the current connection which can then be killed using the mysqli_kill(3) func- tion. If the connection is lost and you reconnect with mysqli_ping(3), the thread ID will be other. Therefore you should get the thread ID only when you need it. Note The thread ID is assigned on a connection-by-connection basis. Hence, if the connection is broken and then re-established a new thread ID will be assigned. To kill a running query you can use the SQL command KILL QUERY processid. PARAMETERS
o $ link -Procedural style only: A link identifier returned by mysqli_connect(3) or mysqli_init(3) RETURN VALUES
Returns the Thread ID for the current connection. EXAMPLES
Example #1 $mysqli->thread_id example Object oriented style <?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s ", 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 ", $mysqli->error); exit; } /* close connection */ $mysqli->close(); ?> Procedural style <?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s ", 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 ", mysqli_error($link)); exit; } /* close connection */ mysqli_close($link); ?> The above examples will output: Error: MySQL server has gone away SEE ALSO
