Answer 1

The code to print row should be inside foreach loop in a specific condition. And the condition for printing row should be as:

<?php
foreach ($location_list as $key => $location) {
    if ($key % 3 == 0) {
        echo '<div class = "row">';
    }

    echo "<div class ='col-md-4'>
          <hr> $location->address </hr>
           <hr> $location->name </hr>
           <hr> $location->pin </hr>
       </div> ";

    if ($key % 3 == 2) {
        echo '</div>';
    }
}
?>
