I'm trying to set up a Google logon authentication system using PHP that sends its data to into a MySQL database. I've gotten as far as getting the files done and putting them all into my C:\xampp\htdocs directory but this is what happens when I open http://localhost/login.php
Warning: require_once(googleapi/vendor/autoload.php): failed to open stream: No such file or directory in C:\xampp\htdocs\config.php on line 3
Fatal error: require_once(): Failed opening required 'googleapi/vendor/autoload.php' (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\config.php on line 3
Here are all my codes
//login.php file
<?php
require_once "config.php";
if (isset($_SESSION['access_token'])) {
header('Location: index.php');
exit();
}
$loginURL = $gClient->createAuthUrl();
?>
