I figured out how to write user info from a registration page to a .dat file but I am stuck at trying to validate a user on the sign in page by cross checking with the .dat if their information matches.
My sign in page code consists of this:
<?php
include "functions.inc";
// Useful variables
$datafile = "users.dat";
if (array_key_exists('submit', $_POST))
// Function to check the password length
{
$the_user = $_POST['newuser'];
// Load the file of users and store it in $users
$users = arrayfile_to_array($datafile);
$users = arrayfile_to_array($datafile);
// Validate user name and password
}
else
{
$users = arrayfile_to_array($datafile);
// Validate the email address
if (!user_unique($users, $the_user['newuser']))
echo "User already exists!";
}
if (array_key_exists('submit', $_POST))
// Function to check the password length
{
header('Location: 04invoice.php');
}
else
if (array_key_exists('register', $_POST))
{
header('Location: 03registration.php');
}
?>

I am trying to use arrayfile_to_array to bring up the file with all the arrays but I am lost as to how to use it. Any tips would greatly be appreciated.
// Open the file
// If the file doesn't exist, create it.
if (!file_exists($datafile))
{
$users = array();
array_to_arrayfile($users, $datafile);
}
else
{
$users = arrayfile_to_array($datafile);
}
}
