Step 1. Create a PHP file and define markup

I simply Create a PHP file as well save it with a name password.php

<?php
session_start();

if(isset($_POST['submit_pass']) && $_POST['pass'])
{
 $pass=$_POST['pass'];
 if($pass=="98256")
 {
  $_SESSION['password']=$pass;
 }
 else
 {
  $error="sorry dear, your Incorrect Pssword";
 }
}

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

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

<?php
if($_SESSION['password']=="98256")
{
 ?>
 <h1>Create Password Protected Webpage Using PHP, HTML And CSS - www.pakainfo.com</h1>
 <form method="post" action="" id="logout_form">
  <input type="submit" name="home_sign_out" value="LOGOUT">
 </form>
 <?php
}
else
{
 ?>
 <form method="post" action="" id="signin_frm">
  <h1>Sign In TO PROCEED</h1>
  <input type="password" name="pass" placeholder="************">
  <input type="submit" name="submit_pass" value="DO SUBMIT">
  <p>"Password : 98256"</p>
  <p><font style="color:red;"><?php echo $error;?></font></p>
 </form>
 <?php	
}
?>

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

In this phase i first of all check if user sign in or not by verifyed then session variable if the user is not sign in i will show signin form and if user is sign in i showing webpage data content with sign out button.i use main two isset() condition to do signin or sign out.In simple main condition i simply read the user password as well as check if the set of the password is ‘98256’ if yes i update the password in session variable using php as well as then show the webpage.In onther condition i simply unset the session variable using php which stores/saved password value.You may also such as a simple http secure authentication using PHP source code.

i create a CSS file and save it with a name password_style.css

body
{
 margin:0 auto;
 padding:0px;
 text-align:center;
 width:100%;
 font-family: "Myriad Pro","Helvetica Neue",Helvetica,Arial,Sans-Serif;
 background-color:#8A4B08;
}
#wrapper
{
 margin:0 auto;
 padding:0px;
 text-align:center;

 padding:20px;
 box-sizing:border-box;
 box-shadow:0px 0px 10px 0px #3B240B;
}
#signin_frm h1
{
 margin:0px;
 font-size:25px;
 color:#8A4B08;
}
#signin_frm input[type="password"]
{
 width:250px;

Easy way to password-protect php page

in this way simply you can Create two files:

protect-this.php
login.php:

protect-this.php

<?php
    $password = '[email protected]';

    if (empty($_COOKIE['password']) || $_COOKIE['password'] !== $password) {
        header('Location: login.php');
        exit;
    }
?>

login.php:

<?php
    $password = '[email protected]';

    $redirect_after_login = 'index.php';
    $remember_password = strtotime('+30 days'); // 30 days

    if (isset($_POST['password']) && $_POST['password'] == $password) {
        setcookie("password", $password, $remember_password);
        header('Location: ' . $redirect_after_login);
        exit;
    }
?>
<!DOCTYPE html>
<html>
<head>
    <title>Password protected - www.pakainfo.com</title>
</head>
<body>
    <div style="text-align:center;margin-top:50px;">
        You must enter the password to view this content.
        <form method="POST">
            <input type="text" name="password">
        </form>
    </div>
</body>
</html>

Note: Then you can simply need to protect-this.php on the TOP of the main files you want to protect:
Password protect this content

require_once('protect-this.php');
