When we create profile system we must have an option of password recovery. In other terms we must have an option of forgot password to reset so that a user can reset password on forgetting.
Here in this tutorial we have created a link of forgot password .When a user click on this link then a input box for email loads on webpage. User will fill the email and click on forgot button to reset the password. A user will get link to reset password on contact email address which user entered for reset.

<?php
mysql_connect('db host','db user','db password');
mysql_select_db('db name');
?>

index.php

<div id="log">
<form action="#" method="POST" id="login">
<center><h4>Login Here</h4></center>
<label>Email</label><input type="email" name="email" id="email"><br>
<label>Password</label><input type="password" name="pass" id="name"><br>
<input type="submit" name="login"  value="Login"><br><br><br> 
</form>
<a href="forgot_pass.php"  >Forgot password</a>
</div>

<?php
include 'config.php';
if(isset($_POST['login']))
{

$email = mysqli_real_escape_string($conn,$_POST['email']);
$pass = mysqli_real_escape_string($conn,$_POST['pass']);

$result = mysqli_query($conn,"SELECT * FROM `user` WHERE `email`='".$email."' and `password`='".md5($pass)."'");
$logresult = mysqli_fetch_array($result);

if(count($logresult)>=1)
{
echo "Login Successfully";
echo "HI".$result['name'];
}
else
{
echo "Email Address or password is incorrect"."<br>";
echo "try again";
}
}
?>

The process of forgot password starts when a user click on forgot password link which we have mentioned above in form. User will go to forgot_pass.php where he will get a input box for enter mail. When user submits mail, first of all validate mail and checking for its existence in DB records. After success send mail to user mail address to verify and then user get an option to fill password and confirm password.

<?php 
if(isset($_POST['submit'])){

$email =$_POST['email'];

$email=mysql_real_escape_string($email);

if (!filter_var($email, FILTER_VALIDATE_EMAIL))
{
echo("$email is not a valid email address");
} 
else {
$emailrecord = mysql_query("SELECT * FROM `user` WHERE `email`='".$email."'");

if(mysql_num_rows($emailrecord)>0)
   {
$rcode=rand(50,999);
$subject ="Reset Password";
