如何使用PHP代码获取Openfire Server中用户的上次注销时间

Question

How to get Last Logout time of user in Openfire Server using php code. How i will achieve this I am new on Openfire.

I googled a lot. But haven't found any article about my questions. Is there any way to get "last seen" or "last activity" date from Openfire server?

Please help me. Thanks in advance.

Answer 1

You can use XMPPHP library to manage XMPP connection to Openfire in PHP; there are several fork from the project originally hosted on Google Code, for example:

• https://github.com/BirknerAlex/XMPPHP
• https://github.com/cweiske/xmpphp

Example of usage are easy to find, however here are some of them:

• XMPPHP to Openfire
• XMPPHP and Openfire

In your case, after having created your connection to XMPP server (Openfire) with:

$conn = new XMPPHP_XMPP(...);
$conn->connect();

you can send a generic XML message with $conn->send($xml); or a specific IQ message with $conn->sendIq(...); .

Follow xep-0012 doc to create appropriate XML to obtain Last Activity info for a user.

Answer 2

If you don't want to communicate on XMPP and you have access to Openfire's database, then you can also query the database for last seen time.

Table: ofPresence

You can query for "offlineDate" against "username" and you will get time in milliseconds: 001448886257729

Whenever a user comes online (sends his presence to Openfire Server), his entry is removed from this table. So for an online user, you won't get any record.

Hope it will help.
