How to print entity referenced fields (node) title in node.tpl.php?
OK, without knowing anything about stdClass Object these kind of questions are normal :)

So, after reading a question about stdClass Object in SO I did what I want as below:

&lt;?php print $node-&gt;field_my_entity_reference['und'][0]['entity']-&gt;title; ?&gt;


This prints the title as plain text.

Note: Is there another way or better way you're always welcome.
