mysql_thread_id
(PHP 4 >= 4.3.0, PHP 5, PECL mysql:1.0)
mysql_thread_id — Return the current thread ID
Description
int mysql_thread_id
([ resource $link_identifier
] )
Retrieves the current thread ID. If the connection is lost, and a reconnect with mysql_ping() is executed, the thread ID will change. This means only retrieve the thread ID when needed.
Parameters
- link_identifier
-
The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level error is generated.
Return Values
The thread ID on success, or FALSE on failure.
Examples
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 will output something similar to:
current thread id is 73
