mysql_thread_id

(PHP 4 >= 4.3.0, PHP 5)

mysql_thread_id -- Return the current thread ID

Description

int mysql_thread_id ( [resource link_identifier])

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.

Example 1. mysql_thread_id() example

<?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);
}
?>

The above example would produce the following output:

current thread id is 73
