Stefin, your program is missing 1 line.

$userInfo = mysqli_fetch_assoc($result); 

This need to be added after code

if ($result->num_rows == 0) {
    die("User with email address <b>$email</b> not found");
} 

What that line do is fetch (means read, get, etc..) user information from MySQL query result.

@annie made that mistake (but actual code worked, i verified), @sherly copied it @stefin reported the mistake :D

This is wrong code. You put code for index.html in lost_password.html

Please reupload the code, try to understand, if you don't understand ask here, that help everyone.

Now stefin asked the question, and we found a problem with posted codes.

[stefin]

Code Fixed, Mail received with password.

 <?php
if (isset($_POST['email'])) {    $email = $_POST['email'];} else {    die('Please enter your email address');}
$email = trim($email);
$db_server = '127.0.0.1';$db_user = 'fwhphp_user';$db_password = 'k5BJRaX6SFbs';$db_name = 'fwhphp_db';
$mysqli = new mysqli($db_server, $db_user, $db_password, $db_name);
if ($mysqli->connect_errno) {    echo 'Connect failed: ' . $mysqli->connect_error;    exit();}
$sql = "select * from users where email='$email'";
$result = $mysqli->query($sql);

if ($result->num_rows == 0) {    die("User with email address <b>$email</b> not found");}
$userInfo = mysqli_fetch_assoc($result);
$name = $userInfo['name'];$password = $userInfo['password'];mail($email,"Your password", "Hello $name, your password is $password");
echo 'New Password send to your email';
