## Overview

Journaling Project is a PHP/MySQL web app for account-based daily journaling. Users sign up or log in, then add tasks, diary entries, and answers to predefined questions; they can review and manage today's entries or search past dates. The map preserves the separate authentication, daily-entry, question-management, history, and editing responsibilities. Source excerpts establish most calls and database operations; the SQL schema and some page behavior are unsampled, so their links are omitted where not directly evidenced.

Main entry points: [`ConfigDB.php`](https://github.com/ahmed-arafat10/journaling-website/blob/master/ConfigDB.php) (Authentication and date helpers), [`Login.php`](https://github.com/ahmed-arafat10/journaling-website/blob/master/Login.php) (Login), [`TodayList.php`](https://github.com/ahmed-arafat10/journaling-website/blob/master/TodayList.php) (Today's entries), [`History.php`](https://github.com/ahmed-arafat10/journaling-website/blob/master/History.php) (Date search and history)
