When rewriting the theme, I encountered a rather annoying problem:

If this code is inserted into the PHP file, an error will be reported:

[16-Aug-2016 13:45:49 UTC] PHP Parse error: syntax error, unexpected 'active' (T_STRING), expecting ',' or ';' in /home/sunhbjaq/public_html/site/snippets/ sidebar.php on line 17

After removing class="active", it will return to normal.
How to solve it? Thanks. (Newbie, please answer patiently, thank you very much!)
Note: Full text of sidebar.php:

 
 
  
author()) ?>
 
authorintroduction()) ?>

This is a syntax error. Please upload the code. Thank you.
