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.
注意:
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
例 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();
?>

例 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:
