模板中的Joomla php echo元机器人标签?

I wonder if it's possible to php echo the robots meta tag in a template in Joomla.

For example, if I do something like this:

$doc =JFactory::getDocument(); 
$meta_description = $doc->getMetaData("description"); 

I can echo the meta description via

<?php echo "$meta_description"; ?>

Is this also somehow possible with the robots tag?

Thanks in advance.

Robots configuration is part of the main Joomla! configuration hence you can retrieve it with:

$jconfig = JFactory::getConfig();
$robots = $jconfig->get('robots', '');

The default (installation) value is an empty string, otherwise you can expect it to have a combination of the values: index,follow,noindex,nofollow.
