First, let's build the SQL of our posts. The database table should contain at the very least the post title, post content, post date, and modified and published dates.

This is what the SQL should look like:

CREATE TABLE posts( 
id INT(11) PRIMARY KEY AUTO INCREMENT, 
post_title TEXT, 
post_content TEXT, 
post_date DATETIME,

Let's start by creating the admin system. We need to log in, so we'll have to create a simple login-logout script:

//admin.php 
<form action="admin.php" method="post">
