Я только что обновился до PHP5 — все устарело, Apache пуст

Я понятия не имею, какую версию PHP я использовал раньше, но я предполагаю, что это была старая версия, потому что она работала очень хорошо, прежде чем я переключился с Nginx на Apache. Я думаю, что я использовал более старую версию PHP на Nginx. В любом случае это пример кода, который считается устаревшим. Я сейчас на PHP 5.5.9.

<?php
// Establishing Connection with Server by passing server_name, user_id and password as a parameter
$connection = mysql_connect("localhost", "username", "password");
// Selecting Database
$db = mysql_select_db("database", $connection);
session_start();// Starting Session
// Storing Session
$user_check=$_SESSION['login_user'];
// SQL Query To Fetch Complete Information Of User
$ses_sql=mysql_query("select name from table where name='$user_check'", $connection);
$row = mysql_fetch_assoc($ses_sql);
$login_session =$row['name'];
if(!isset($login_session)){
mysql_close($connection); // Closing Connection
header('Location: index.php'); // Redirecting To Home Page
}
?>

Все мои страницы используют PHP-код, похожий на этот, поэтому я просто опубликую один из них. Это мой журнал ошибок.

Если бы кто-то мог переписать весь код PHP, который я выложил выше, в формате PHP 5, чтобы я знал, с чего начать, это было бы здорово. В настоящее время Apache2 — это просто пустой сайт, на котором работают только пара HTML-элементов. Извините, если это звучит как нубский вопрос, я бы просто хотел ссылку.

Есть два файла php.ini. Один из них находится в / etc / php5 / apache2

PHP INI подключен внешне, потому что у меня нет достаточно комнаты, чтобы разместить его здесь
