How to fetch data separeted by comma and store it in checkbox as checked in php

How to retrieved data separated by comma and store it in checkbox as checked. I'm using explode so that the string data converted into an array. My problem is I can't get the logic behind this code. For example the data are "Parents, Grandparents, Friends" and I want to checked the checkbox depends upon that data. Thank you in advance. Here's my code not working:

<?php 
  $db_living_whom = explode(",", $fetch['living_whom']);
?>

<label>Living with whom</span></label>
    <div class="row">
      <?php 
       foreach ($db_living_whom as $value) {
      ?>
      <div class="col-md-2">
        <label class="checkbox-inline">Parents
          <input type="checkbox" <?php if($value == "Parent") echo "checked"; ?> disabled>
        </label>
      </div>
      <div class="col-md-3">
        <label class="checkbox-inline">Brothers & Sisters
          <input type="checkbox" <?php if($value == "Brothers & Sister") echo "checked"; ?> disabled>
        </label>
      </div>
      <div class="col-md-2">
        <label class="checkbox-inline">Grandparents
          <input type="checkbox" <?php if($value == "Grandparents") echo "checked"; ?> disabled>
        </label>
      </div>
      <div class="col-md-2">
        <label class="checkbox-inline">Other Relatives
          <input type="checkbox" <?php if($value == "Other Relatives") echo "checked"; ?> disabled>
        </label>
      </div>
      <div class="col-md-2">
        <label class="checkbox-inline">Friends
          <input type="checkbox" <?php if($value == "Friends") echo "checked"; ?> disabled>
        </label>
      </div>
    <?php } ?>
    </div>

In that code the checkboxes load 4 times (because of foreach loop) and the "Parents, Grandparents, Friends" are not checked.
