maxdb_thread_id

(PECL)maxdb_thread_id

(no version information, might be only in CVS)maxdb->thread_id -- Returns the thread ID for the current connection

Description

Procedural style:int maxdb_thread_id (resource link)

Object oriented style (property):class maxdb {


int 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.

Замечание: 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.

Return values

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

Example

Пример 1. Object oriented style

<?php

$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

/* 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();

?>

Пример 2. Procedural style

<?php

$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */

if (maxdb_connect_errno()){

printf("Connect failed: %s\n", maxdb_connect_error());

exit();

}

/* determine our thread id */

$thread_id = maxdb_thread_id($link);

/* Kill connection */

maxdb_kill($link, $thread_id);

/* This should produce an error */

if (!maxdb_query($link, "CREATE TABLE mycity LIKE hotel.city")){

printf("Error: %s\n", maxdb_error($link));

exit;

}

/* close connection */

maxdb_close($link);

?>

The above examples would produce the following output: 

Warning: maxdb_query(): -10821 Session not connected <...>

Error: Session not connected
