## Overview

This is a small PHP/MySQL car-rental website prototype: visitors search a car listing and open a car detail page, while an admin area provides an early management interface. The tree contains several parallel directories; the sampled public listing/detail flow is under `autorent/`, while the sampled admin pages are under `car_rent/`. The README also outlines authentication, user accounts and reservations as later stages, but the tree has no corresponding runtime implementation, so these are shown as documented plans rather than wired features.

Main entry points: [`car_rent/admin/index.php`](https://github.com/metshein/car_rent/blob/main/car_rent/admin/index.php) (Admin listing), [`autorent/index.php`](https://github.com/metshein/car_rent/blob/main/autorent/index.php) (Car listing), [`autorent/single_car.php`](https://github.com/metshein/car_rent/blob/main/autorent/single_car.php) (Car detail), [`car_rent/car_edit.php`](https://github.com/metshein/car_rent/blob/main/car_rent/car_edit.php) (Car editor)
