如何在Yii2中注释掉结构<?=?>

a trivial question, but all my efforts to comment out code lines like this:

<?=$form->field($model, 'bew_id')->textInput(['placeholder' => 'Bew']) ?>

failed by using PHP and/or HTML-comments.Following trys didn't success:

//

/* */

<-!- -->

Any ideas??

Change <?= to <?php and then do the comment

<?php /*echo  $form->field($model, 'bew_id')->textInput(['placeholder' => 'Bew']) */ ?>

because this

<?= $form->field($model, 'bew_id')->textInput(['placeholder' => 'Bew']) ?>

is shorthand for

<?php echo $form->field($model, 'bew_id')->textInput(['placeholder' => 'Bew']) ?>

use any comment // or /* */

Remove <?= at the beginning then you can comment by using <!-- as follows

<!---$form->field($model, 'bew_id')->textInput(['placeholder' => 'Bew']) ?>-->
