<?php session_start(); ?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<link rel="stylesheet" href="bootstrap/bootstrap.css">
<title>Login System in PHP</title>
</head>
<body style="background:#CCC;">
<nav class="navbar navbar-expand-sm navbar-dark bg-dark">
<div class="container">
<a href="index.php" class="navbar-brand"><h3>Login System</h3></a>
<div class="collapse navbar-collapse">
<ul class="nav navbar ml-auto">
<?php
if(isset($_SESSION['U_D']))
{
echo '<form action="includes/logout.php" method="POST">
<li class="nav-item"><button type="submit" name="logout" class="btn btn-outline-light">Logout</button></li>
</form>';
}
else
{
echo ' <li class="nav-item"><a href="logindesign.php" class="btn btn-outline-light">Login</a></li>
<li class="nav-item"><a href="signupdesign.php" class="btn btn-outline-light ml-3">Sign Up</a></li>';
}
?>
</ul>
</div>
</div>
</nav>Then the next step is you need to create Footer.PHP file. In this file, you need to enter more two codes I mentioned below.
</body> </html>Once you have successfully made the mentioned files and paste the codes. You need to Design Login Form, I mentioned LoginDesign.PHP Code on below, you can copy that and create a new file and paste the code.

<?php require_once('footer.php'); ?>Then, you need to create a database and also a table to store the Application data. I mentioned code on below, you can use the same code the paste with your own created database. My Table Name is Users.
create table Users
(
user_id int primary key AUTO_INCREMENT,
user_first varchar(50),
user_last varchar(50),
user_email varchar(50),
user_uid varchar(50),
user_password varchar(300)
)Then the next step is you need to make connection.php file. In this file, you need to make the connection between PHP and MySQLi Database.
<?php
$con=mysqli_connect('localhost','root','','usersystem');
if(!$con)
{
die('Connection Error'.mysqli_error());
}
?>After creating Connection.php file, you need to work on PHP. So let’s get started to work on PHP to make Login System in Php with validation.

First of All, you need to make file signup.php file, in this file you need to get the data from users and enter validation, below, I mentioned codes.
<?php
require_once('connection.php');
if(isset($_POST['signup']))
{
if(empty($_POST['FName']) || empty($_POST['LName']) || empty($_POST['Email']) || empty($_POST['UserName']) || empty($_POST['password']))
{
header("location: ../signupdesign.php?empty");
}
else
{
$FName=mysqli_real_escape_string($con,$_POST['FName']);
$LName=mysqli_real_escape_string($con,$_POST['LName']);
$Email=mysqli_real_escape_string($con,$_POST['Email']);
$UserName=mysqli_real_escape_string($con,$_POST['UserName']);
$Password=mysqli_real_escape_string($con,$_POST['password']);
if(!preg_match("/^[a-zA-Z]*$/",$FName) || !preg_match("/^[a-zA-Z]*$/",$LName))
{
header("location: ../signupdesign.php?Invalid");
exit();
}
else
{
if(!filter_var($Email,FILTER_VALIDATE_EMAIL))
{
header("location: ../signupdesign.php?VEmail");
exit();
}
else
{
$query = " select * from userlogin where UserName='".$UserName."'";
$result = mysqli_query($con,$query);
if(mysqli_fetch_assoc($result))
{
header("location: ../signupdesign.php?User");
exit();
}
else
{
$query = " select * from userlogin where Email='".$Email."'";
$result = mysqli_query($con,$query);
if(mysqli_fetch_assoc($result))
{
header("location: ../signupdesign.php?Email");
exit();
}
else
{
$Hash = password_hash($Password, PASSWORD_DEFAULT);
$query = " insert into userlogin (FName,LName,Email,UserName,Password) values ('$FName', '$LName', '$Email', '$UserName','$Hash')";
$result = mysqli_query($con,$query);
header("location: ../signupdesign.php?success");
exit();
}
}
}
}
}
}
else
{
header("location: ../index.php");
exit();
}
?>Once you have made the signup.php file, then you are able to store the value in the database with validation and also the encrypted password.

require_once('connection.php');
if(isset($_POST['login']))
{
if(empty($_POST['UserName']) || empty($_POST['password']) )
{
header("location: ../logindesign.php?empty");
exit();
}
else
{
$UserName = mysqli_real_escape_string($con,$_POST['UserName']);
$Password = mysqli_real_escape_string($con,$_POST['password']);
$Query = " select * from userlogin where UserName='".$UserName."' or Email='".$UserName."'";
$result = mysqli_query($con,$Query);
if($row=mysqli_fetch_assoc($result))
{
$HashPass = password_verify($Password,$row['Password']);
if($HashPass==false)
{
header("location: ../logindesign.php?P_Invalid");
exit();
}
elseif($HashPass==true)
{
$_SESSION['U_D']=$row['ID'];
$_SESSION['FName']=$row['FName'];
$_SESSION['LName']=$row['LName'];
$_SESSION['Email']=$row['Email'];
$_SESSION['UserName']=$row['UserName'];
$_SESSION['Password']=$row['Password'];
header("location: ../account.php?Well");
exit();
}
}
else
{
header("location: ../logindesign.php?U_Invalid");
exit();
}
}
}
else
{
header("location: ../logindesign.php");
exit();
}
?>Once you have complete all process, you need to do another work like logout process, user login your application and also log out.
So, You need to make logout.php file and paste below code, that’s it, guys.
<?php
if(isset($_POST['logout']))
{
session_start();
session_unset();
session_destroy();
header("location: ../index.php");
exit();
}
