Html is still visible in CodeIgniter using if else - php

Question

I'm here trying to make if else condition to hiding the html part if $addons_facts var is empty. I am making the addon visible on the food item if the $addons_facts var is not empty.
<?php $addon_data = $this->addons_model->get_addon_by_menu_id($menu_details['id']);
$addons_facts = json_decode($addon_data->addon_fact, true);
?>
<?php if(!empty($addons_facts) && $addons_facts !=='') : ?>
<div class="form-group">
<div class="row">
<div class="col-md-12">
<?php
foreach ($addons_facts as $key => $addon_fact) : ?>
<div class="row">
<div class="col-md-1">
<div class="checkbox">
<label for="check">
<input type="checkbox" id="check" />
<span class="fake-input"></span>
</label>
</div>
</div>
<div class="col-md-7 text-left">
<?php echo sanitize($key); ?>
</div>
<div class="col-md-3">
<?php echo currency(sanitize($addon_fact));?>
</div>
</div>
<?php endforeach; ?>
</div>
</div>
</div>
<?php endif; ?>
When data is present in $addons_facts
When data is absent $addons_facts
As you can clearly see that when data is not present and the html is still visible (checkbox or $). I already tried if else both but unable to figure it out what is going wrong and why if condition not hiding the whole content within if{}.

I figure it out the solution by this: <?php if(!empty($key)) : ?>
<div class="form-group">
<div class="row">
<div class="col-md-12">
<?php
foreach ($addons_facts as $key => $addon_fact) : ?>
<?php if(!empty($key)) : ?>
<?php $randomNum = substr(str_shuffle("0123456789abcdefghijklmnopqrstvwxyzABCDEFGHIJKLMNOPQRSTVWXYZ"), 0, 10); ?>
<div class="row">
<div class="col-1">
<div class="checkbox">
<label for="<?php echo $randomNum; ?>">
<input type="checkbox" id="<?php echo $randomNum; ?>" />
<span class="fake-input"></span>
</label>
</div>
</div>
<div class="col-7 text-left">
<?php echo sanitize($key); ?>
</div>
<div class="col-3">
<?php echo sanitize($addon_fact) ? currency(sanitize($addon_fact)) :'';?>
</div>
</div>
<?php endif; ?>
<?php endforeach; ?>
</div>
</div>
</div>
