Not able to comment a short open tag in PHP using netbeans

Question

Netbeans is giving a syntax error when commenting a short open tag like so

<?= // echo ... ?>

It works perfectly fine when I comment default tag

<?php // echo ... ?>

I have short_open_tag enabled in php.ini and I checked allow short tag in netbeans project

Answer 1

Ctrl-1 to open your Project window
Right-click on your project and click on Properties
Enable Allow short tags (<?)

Answer 2

You've to comment like that:

<?//= ... ?>

And no need to write echo if you're using short hand tags. As = means echo in that case.
