mysqli_thread_id (PHP 5) mysqli_thread_id (no version information, might be only in CVS) mysqli->thread_id -- Returns the thread ID for the current connection DescriptionProcedural style: int mysqli_thread_id ( mysqli link ) Object oriented style (property): class mysqli { int thread_id }
The mysqli_thread_id() function returns the thread
ID for the current connection which can then be killed using the
mysqli_kill() function. If the connection is lost
and you reconnect with mysqli_ping(), 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.
Return Values
mysqli_thread_id() returns the Thread ID for the current connection.
ExamplesExample 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);
?>
