maxdb_thread_id

maxdb::thread_id

(PECL maxdb >= 1.0)

maxdb_thread_id -- maxdb::thread_id — Returns the thread ID for the current connection

설명

절차식 형식

int maxdb_thread_id ( resource $link )

객체 기반 형식

int $maxdb->thread_id;

The maxdb_thread_id() function returns the thread ID for the current connection which can then be killed using the maxdb_kill() function. If the connection is lost and you reconnect with maxdb_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.

반환값

maxdb_thread_id() returns the Thread ID for the current connection.

Example #1 객체 기반 형식


<?php

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

/* determine our thread id */
$thread_id = $maxdb->thread_id;

/* Kill connection */
$maxdb->kill($thread_id);

/* This should produce an error */
if (!$maxdb->query("CREATE TABLE mycity LIKE hotel.city")) {
   printf("Error: %s\n", $maxdb->error);
   exit;

/* close connection */
$maxdb->close();
