            <strong><?php echo $checkbox1 ?></strong> <input style="width: 50px;" name="<?php echo $checkbox1 ?>" type="checkbox"><
            br>
        </div>
        <div class="col-md-offset-1"> <strong> <?php echo $checkbox1?></strong> <input style="width: 50px;margin-right: -6px;" name="<?php echo $checkbox2 ?>" type="checkbox"><br> </div>

If you are using PHP7, you can use Null coalescing operator

$myVar = $myVar ?? "default value";
// shorthand of $myVar = isset($myVar) ? $myVar : "default value"

Use php short hand ?>. – Adnan Haider Feb 23 '18 at 05:04
*[PHP also allows for short open tag (which is discouraged since it is only available if enabled using the short_open_tag php.ini configuration file directive, or if PHP was configured with the --enable-short-tags option)](http://php.net/manual/en/language.basic-syntax.phptags.php)* – Aniket Sahrawat Feb 23 '18 at 05:07

Looks like you are in way of plain old PHP.

In this case, theres no way to make it short.

Try to use MVC framework like Laravel.
