Definitely.<p>If you want to start working on that, feel free to open up an issue (<a href="https:&#x2F;&#x2F;github.com&#x2F;etsy&#x2F;phan&#x2F;issues&#x2F;new" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;etsy&#x2F;phan&#x2F;issues&#x2F;new</a>) to start a conversation about it.<p>We currently store method&#x2F;function callers in the sqlite database (see <a href="https:&#x2F;&#x2F;github.com&#x2F;etsy&#x2F;phan&#x2F;blob&#x2F;master&#x2F;src&#x2F;Phan&#x2F;Analyze&#x2F;BreadthFirstVisitor.php#L922-L929" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;etsy&#x2F;phan&#x2F;blob&#x2F;master&#x2F;src&#x2F;Phan&#x2F;Analyze&#x2F;Br...</a>), but aren&#x27;t yet exposing an interface for getting callers. We&#x27;ll want to store callers for constants, classes, properties and global variables as well.
