mysqli::kill -- mysqli_kill — Asks the server to kill a MySQL thread
Objektorientierter Stil
Prozeduraler Stil
This function is used to ask the server to kill a MySQL thread specified by the processid parameter. This value must be retrieved by calling the mysqli_thread_id() function.
To stop a running query you should use the SQL command KILL QUERY processid.
Nur bei prozeduralem Aufruf: Ein von mysqli_connect() oder mysqli_init() zurückgegebenes Verbindungsobjekt.
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiel #1 mysqli::kill() example
Objektorientierter Stil
<?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();
?>
Prozeduraler Stil
<?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 examples will output:
Error: MySQL server has gone away
Be careful using this before mysqli::close.
Killing the thread before actually closing the connection will leave the connection open! And depending on your max_connections and max_user_connections (by default the same), this could result in a "Max connections reached for **** user" message.
