mysql_thread_id
Return the current thread ID
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
mysqli_thread_id
|
int|false mysql_thread_id(resource link_identifier= =NULL);
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.
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
had been called with no arguments. If no connection is
found or established, an E_WARNING
level error is generated.
The thread ID on success or false
on
failure.
Example 6.56 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
