'HTTP authentication with PHP for specific pages

I have been trying to fix one issue for the last two weeks but didn't find any solution to my problem. So, I am trying to add HTTP authentication with PHP 7.4.

The main issue

I have to add restrictions for specific URLs ( For example, https://example.com/photos ) with PHP, and I am using the below code. But the problem is I have to show logged-in users on other pages, too. For example, if I didn't log in, then anything to show, but if I am logged in need to show username and password on all pages, but again I have to restrict only specific pages.

PHP Code:

Header("WWW-Authenticate: Basic realm='Members Only' valid-user");
http_response_code(401);
echo "<script> window.location.replace( 'https://example.com/sign-up' ) </script>";
exit;

.htaccess Code:

AuthUserfile PATH_TO_THE_FILE/.htpasswd
AuthName "Members Only"
AuthType Basic
AuthBasicProvider file

I hope someone will help me soon.

This is what I use

Put these 2 files in a folder...change the password fields and the refresh redirect code once correct password is entered.

index.php

    <meta name='robots' content='noindex, nofollow' />
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=5.0, minimum-scale=1">

<?php
session_start();

if(isset($_POST['submit_pass']) && $_POST['pass'])
{
 $pass=$_POST['pass'];
 if($pass=="12345678")
 {
  $_SESSION['password']=$pass;
 }
 else
 {
  $error="Incorrect Pssword";
 }
}

if(isset($_POST['page_logout']))
{
 unset($_SESSION['password']);
}
?>

<html>
<head>
<link rel="stylesheet" type="text/css" href="password_style.css">
</head>
<body>
<div id="wrapper">

<?php
if($_SESSION['password']=="12345678")
{
 ?>
 
 <meta http-equiv="refresh" content="0;url=https://example.com">

 <?php
}
else
{
 ?>
 <form method="post" action="" id="login_form">
  <h1>LOGIN TO PROCEED</h1>
  <input type="password" name="pass" placeholder="*******">
  <input type="submit" name="submit_pass" value="SUBMIT">
  <p><font style="color:red;"><?php echo $error;?></font></p>
 </form>
 <?php  
}
?>

</div>
</body>
</html>
