maxdb_thread_id

maxdb->thread_id

(PECL maxdb:1.0-7.6.00.38)

maxdb->thread_id — Returns the thread ID for the current connection

说明

Procedural style:

int maxdb_thread_id ( resource $link )

Object oriented style (property):

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.

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.

返回值

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

范例

Example#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();
?>

Example#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
