In My Php File, Only The Include Part Is Visible In Browser And Html Code Is Not Working Or Displaying

<?php

include('C:xampphtdocsadminincludesheader.php');

include('C:xampphtdocsadminincludesnavbar.php');

include('C:xampphtdocsadminincludessidebar.php');

?>

<!-- Content Wrapper. Contains page content -->

<div class="content-wrapper">

<!-- Content Header (Page header) --> <div class="content-header">

<div class="container-fluid">

<div class="row mb-2">

<div class="col-sm-6">

<h1 class="m-0 text-dark">Dashboard</h1>

</div><!--/.col --> <div class="col-sm-6">

<ol class="breadcrumb float-sm-right">

<li class="breadcrumb-item"><a href="#">Home</a></li>

<li class="breadcrumb-item active">Dashboard vi</li>

</ol>

</div><!--/.col --> </div><!--/.row -->

</div><!--/.container-fluid -->

</div>



<?php include('C:xampphtdocsadminincludesfooter.php");
?>

 

    <?php

include('C:xampphtdocsadminincludesheader.php');

include('C:xampphtdocsadminincludesnavbar.php');

include('C:xampphtdocsadminincludessidebar.php');

?>

<!-- Content Wrapper. Contains page content -->

<div class="content-wrapper">

<!-- Content Header (Page header) --> <div class="content-header">

<div class="container-fluid">

<div class="row mb-2">

<div class="col-sm-6">

<h1 class="m-0 text-dark">Dashboard</h1>

</div><!--/.col --> <div class="col-sm-6">

<ol class="breadcrumb float-sm-right">

<li class="breadcrumb-item"><a href="#">Home</a></li>

<li class="breadcrumb-item active">Dashboard vi</li>

</ol>

</div><!--/.col --> </div><!--/.row -->

</div><!--/.container-fluid -->

</div>



<?php include('C:xampphtdocsadminincludesfooter.php");
?>

Only the include part displays in browser but html part doesn’t display

Still I didn’t find any solution
