What is wrong with this one line of code? (php inside php)
<p>I'm new to php. I have the following line in a functions.php file of my WordPress site. I think there is something wrong with the way I formatted <code>get_the_bag</code>. Can someone let me know what is wrong?</p>

<p><code>$output .= "&lt;span class='bag-item'&gt;. get_the_bag(); .&lt;/span&gt;";</code></p>
