如何在civicrm中检索标签详细信息？

Which class is used for retrieving tag details using tag id? Any body knows the solution please help me. I have to check the tagged element name on the basis of that I have to create one activity?

Pleae check:

api/v2/Tag.php

A better place for these questions are on the civicrm forums.

Since the question was asked, an improved version was released

$result = civicrm_api3 ("Tag","get", array ("id"=> $yourid, "sequential"=>1));

shoud get you what you want.
