How to Create a Secure Session Management System in PHP and MySQL

Step-by-Step Guide

1. 1

   Step 1: Create a MySQL database.

   In this guide we will create a database called "secure_sessions".
   
   See how to Create-a-Database-in-Phpmyadmin.
   
   Or you can use the SQL code below will create one for you.Create Database Code:
   CREATE DATABASE `secure_sessions` ; Note:
   Some hosting services don't allow you to create a database through phpMyAdmin, Learn how to do it in cPanel.
2. 2

   Step 2: Create a user with only SELECT

   This means that if there was ever a breach of security in our script the hacker couldn't drop tables from our database.
   
   If you're really paranoid, create a different user for each function.
   
   User: "sec_user" Password: "eKcGZr59zAa2BEWU" Create User Code:
   CREATE USER 'sec_user'@'localhost' IDENTIFIED BY 'eKcGZr59zAa2BEWU'; GRANT SELECT, INSERT, UPDATE, DELETE ON `secure_sessions`.* TO 'sec_user'@'localhost'; Note:
   It is a good idea to change the password in the code above when running on your own server. (Make sure you change your PHP code also.) Remember it doesn't need to be a password that you can remember so make is as complicated as possible.
   
   Here's a random password generator. , The code below creates a table with 4 fields (id, set_time, data, session_key).Create the "sessions" table:
   CREATE TABLE `sessions` ( `id` CHAR(128) NOT NULL, `set_time` CHAR(10) NOT NULL, `data` text NOT NULL, `session_key` CHAR(128) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; We use the CHAR datatype for fields we know the length of, as the fields "id" and "session_key" will always be 128 characters long.
   
   Using CHAR here saves on processing power.

   Step 3: INSERT and DELETE privileges.
