PHP login from text file

Question

Hi I have looked at other posts about this but they are 2 or more years old so I thought it was better to start fresh.

As the title suggests I am trying to make a login

Lets say your text file looks something like this:

pete|petepass|pete@somesite.com|Pete Enterprizes
john|johnpass|john@somedomain.com|John Corporation

Your code can read something like this:

$userN = $_POST['user-name'];
$passW = $_POST['pass-word'];
$userlist = file ('users.txt');

$email = "";
$company = "";

$success = false;
foreach ($userlist as $user) {
    $user_details = explode('|', $user);
    if ($user_details[0] == $userN && $user_details[1] == $passW) {
        $success = true;
        $email = $user_details[2];
        $company = $user_details[3];
        break;
    }
}

if ($success) {
    echo "
 Hi $userN you have been logged in. 
";
} else {
    echo "
 You have entered the wrong username or password. Please try again. 
";
}
