## Overview
This repository is a collection of standalone PHP learning exercises, not one integrated application. The main user-to-result patterns are submitting a form and seeing validation/results, progressing through a session-backed registration flow, editing a profile, and viewing database-backed reports. The sampled database pages share a PDO singleton; other exercises are independent. The README is empty, and several small exercises were not sampled, so their behavior and connections are not inferred.
Main entry points: [`session_07/Path3/Database.php`](https://github.com/nguyenquocdai1406-gif/ins306401_ins3064_nguyenquocdai/blob/main/session_07/Path3/Database.php) (PDO Singleton), [`session_03/mini_project/profile.php`](https://github.com/nguyenquocdai1406-gif/ins306401_ins3064_nguyenquocdai/blob/main/session_03/mini_project/profile.php) (Profile Management), [`session_07/Path3/top_customers.php`](https://github.com/nguyenquocdai1406-gif/ins306401_ins3064_nguyenquocdai/blob/main/session_07/Path3/top_customers.php) (Top Customers Report), [`session_07/Path4/index.php`](https://github.com/nguyenquocdai1406-gif/ins306401_ins3064_nguyenquocdai/blob/main/session_07/Path4/index.php) (Product Dashboard)
