How to comment a php line in which there is a condition

How to comment a php line in which there is a condition in a form whose html and css style I am editing locally on my wamp server.
The form works perfectly online but if I don’t comment out the php, I can’t see the rendering (it works with a database and variables).

Only one line is giving me trouble, it’s the line where there is the condition count($errors)>0 🙁

<form action="en_login.php" method="post">
                <h3 class="text-center text-5xl font-Helvetica">Login</h3>
                
                <?php  if (count($errors)>0) {  ?>

                <div class="alert">
                    <?php // foreach ($errors as $error) { ?>
                    <li><?php // echo $error; ?></li>
                    <?php // } ?>
                </div>
                <?php // } ?>
                                

Impossible to not get ” 0) { ?> ” in my html
