mysqli::kill -- mysqli_kill — Asks the server to kill a MySQL thread
This function has been DEPRECATED as of PHP 8.4.0. Relying on this function is highly discouraged.
Stile orientato agli oggetti
Stile procedurale
This function is used to ask the server to kill a MySQL thread specified
by the process_id 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.
linkSolo nello stile procedurale: un identificatore restituito da mysqli_connect() o mysqli_init()
If mysqli error reporting is enabled (MYSQLI_REPORT_ERROR) and the requested operation fails,
a warning is generated. If, in addition, the mode is set to MYSQLI_REPORT_STRICT,
a mysqli_sql_exception is thrown instead.

Both mysqli::kill() and
mysqli_kill() are now deprecated. Use the
KILL SQL command instead.
