## Overview

PG-Life is a PHP property-finding and management site. Visitors search listings by city and gender, open property details, and can register or sign in; signed-in users can save properties of interest and submit reviews. Administrators sign in separately to publish properties and update descriptions. The excerpts show listing, detail, review, and admin-dashboard behavior; other endpoint internals are unsampled, so their links reflect only the visible forms or filenames. The React component is a separate static sample, not shown wired into the PHP workflow.

Main entry points: [`property_detail.php`](https://github.com/gopalakrishna57/pglife/blob/main/property_detail.php) (Property details), [`admin_dashboard.php`](https://github.com/gopalakrishna57/pglife/blob/main/admin_dashboard.php) (Admin dashboard), [`db_connect.php`](https://github.com/gopalakrishna57/pglife/blob/main/db_connect.php) (Database connection), [`property_list.php`](https://github.com/gopalakrishna57/pglife/blob/main/property_list.php) (Property listings)
