mysql_thread_id

Description

mysql_thread_id() returns the current thread id. If the connection is lost and you reconnect with mysql_ping(), the thread ID will change. This means you should not get the thread ID and store it for later. You should get it when you need it.

<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$thread_id = mysql_thread_id($link);
if ($thread_id){
    printf ("current thread id is %d\n", $thread_id);
}
?>
