Back button like in file browser - php

Question

I am creating a document management system for my project. I just want to know if there is a possible way to achieve a back button like in the photo below.
see the photo here
Here is my code for the document management system:
index.php
<main class="page-content">
<div class="container-fluid">
<div class="breadcrumb">
<div class="item"> Document</div>
</div>
<div class="load-data">
<?php
require_once 'config.php';
$sql = "SELECT * FROM tbl_menu WHERE parent='0' ORDER BY sort ASC";
$folders = $db->prepare($sql);
$folders->execute();
$folder = $folders->fetchAll();
if ($folder) {
echo "<table>";
echo "<thead>
<tr>
<td>Label</td>
<td>Sort</td>
<td>Id</td>
</tr>
</thead>";
foreach ($folder as $folderr) {
echo "<tr class='folder-item'>";
if($folder['link'] == 'folder'){
echo" <td><i class'fa fa-folder'><a href='#' onclick='get_data(".$folderr['id'].")'>".$folderr['label']."</a></td>";
}else{
echo" <td><i class='fa fa-file'></i><a href='#' onclick='get_data(".$folderr['id'].")'>".$folderr['label']."</a></td>";
}
echo" <td>".$folderr['sort']."</td>
<td>".$folderr['id']."</td>
</tr>";
}
echo "</table>";
} else {
echo 'No folder/files found.';
}
?>
</div>
</div>
</main>
</div>
here's the script
<script>
function get_data(id){
$.ajax({
type : 'GET',
url : 'file.php',
data : 'folder=' + id,
success : function(response){
$('.load-data').html(response);
}
});
}
$('.folder-item a').on('click', function() {
var $this = $(this),
$bc = $('<div class="item"></div>');
$this.parents('td').each(function(n, td) {
var $a = $(td).children('a').clone();
$bc.append(' > ', $a);
});
$('.breadcrumb').html( $bc.prepend('Document') );
return false;
});
</script>
here's the file.php
<?php
require_once 'config.php';
if(isset($_GET['folder'])){
$id = $_GET['folder'];
$sql = "SELECT * FROM tbl_menu WHERE parent='$id' ORDER BY sort ASC";
$folders = $db->prepare($sql);
$folders->execute();
$folder = $folders->fetchAll();
if ($folder) {
echo "<table>";
echo "<thead>
<tr>
<td>Label</td>
<td>Sort</td>
<td>Id</td>
</tr>
</thead>";
foreach ($folder as $folderr) {
echo "<tr>";
if($folder['link'] == 'folder'){
echo" <td><i class'fa fa-folder'><a href='#' onclick='get_data(".$folderr['id'].")'>".$folderr['label']."</a></td>";
}else{
echo" <td><i class='fa fa-file'></i><a href='#' onclick='get_data(".$folderr['id'].")'>".$folderr['label']."</a></td>";
}
echo" <td>".$folderr['sort']."</td>
<td>".$folderr['id']."</td>
</tr>";
}
echo "</table>";
} else {
echo 'No folder/files found.';
}
}
?>
