+# PHP + PostgreSQL Visit Counter
+
+This project implements a PHP web application for counting visits, backed by a PostgreSQL database. It is containerized using Docker and Docker Compose, and provides automated deployment scripts (to Plesk via Git) as well as deployment cleanup scripts.

+
+## Overview
+
+This simple application counts the number of visits to a web page. On each page load, a new entry is inserted into the `visitors` table in PostgreSQL, and the total count is displayed.
+
+A button allows to choose between light and dark themes via JavaScript and `localStorage`.
+
+The project includes:
+
+- A **PostgreSQL** container with automatic table initialization via `db.sql`.  
+- A **PHP 8.2 + Apache** container serving the application.  
+- A **Dockerfile** to build the web image (with the `pdo_pgsql` extension installed).  
+- A **docker-compose.yml** to orchestrate both services.  
+- A **prepare-app.sh** script for force-pushing deployments to Plesk via Git.  
+- A **remove-app.sh** script for cleaning up the remote deployment.
+
+---
+
+## Features
+
+- Automatically inserts a row into the `visitors` table on each load (`INSERT INTO visitors DEFAULT VALUES`).  
+- Automatically creates the table if it doesn’t exist (`CREATE TABLE IF NOT EXISTS visitors …`).  
+- Displays the visit counter.  
+- Light/dark theme toggle, persisted in `localStorage`.  
+- Automated Git deployments (Plesk).  
+- Remote cleanup of pushed content.
+
+---
+
+## Prerequisites
+
+- **Docker** (>= 20.x)  
+- **Docker Compose** (>= 1.27.x)  
+- **Git** (for the deployment scripts)  
+- Access to a Plesk instance with a Git-configured repository (for `prepare-app.sh` and `remove-app.sh`)
+
+---
+
+## Installation & Configuration
+
+### Project Structure
+
+```text
+├── db.sql               # SQL script to initialize the `visitors` table
+├── Dockerfile           # Builds the PHP + Apache + pdo_pgsql image
+├── docker-compose.yml   # Docker orchestration (db + web)
+├── prepare-app.sh       # Deployment script to Plesk
+├── remove-app.sh        # Remote cleanup script
+├── index.php        # Main page (insertion + count + front-end)
+└── drop.php         # Script to drop the `visitors` table
+```
+
+### Environment Variables
+
+In `docker-compose.yml`, for the **db** service:
+
+```yaml
+POSTGRES_DB: visitors
+POSTGRES_USER: visitor_user
+POSTGRES_PASSWORD: secret
+```
+
+And for the **web** service:
+
+```yaml
+DB_HOST: db
+DB_PORT: 5432
+DB_NAME: visitors
+DB_USER: visitor_user
+DB_PASS: secret
+```
+
+
+
+
+### Prepare Script (`prepare-app.sh`)
+
+This script initializes the Git repo (if needed), adds a `tuke` remote pointing to the Plesk instance, commits all changes, then force-pushes the branch (`master` or `main`).
+
+```bash
+chmod +x prepare-app.sh
+./prepare-app.sh
+```
+
+
+---
+
+## Usage
+
+
+### Application Entry Point
+
+`index.php` performs:
+
+1. Connects to PostgreSQL via PDO (`pgsql:host=$dbHost;port=$dbPort;dbname=$dbName`).  
+2. Runs an embedded SQL migration to create the `visitors` table if it doesn’t exist.  
+3. Inserts a new row:
+   ```php
+   $pdo->exec("INSERT INTO visitors DEFAULT VALUES");
+   ```
+4. Retrieves the total count:
+   ```php
+   $count = $pdo->query("SELECT COUNT(*) FROM visitors")->fetchColumn();
+   ```
+5. Generates the HTML/CSS/JS to display the counter and manage the theme.
+
+### Table Reset (`drop.php`)
+
+The script `drop.php` connects to the same database and runs:
+
+```php
+$pdo->exec("DROP TABLE IF EXISTS visitors");
+echo "Table visitors dropped.";
+```
+
+On error it returns HTTP 500 and displays the exception message.
+
+---
+
+## Deployment to Plesk
+
+To deploy automatically:
+
+1. Configure `GIT_REMOTE_URL` and `BRANCH` in `prepare-app.sh`.  
+2. Make it executable and run:
+   ```bash
+   chmod +x prepare-app.sh
+   ./prepare-app.sh
+   ```
+This force-pushes the branch to Plesk’s `httpdocs`, updating the remote site.
+
+---
+
+## Deployment Cleanup (`remove-app.sh`)
+
+To clear the remote content without touching the local repository:
+
+1. Make it executable:
+   ```bash
+   chmod +x remove-app.sh
+   ```
+2. Run:
+   ```bash
+   ./remove-app.sh
+   ```
+This clones the remote into a temp directory, removes all tracked files, commits, and force-pushes, then cleans up.
+
+---
+
+## Detailed File Structure
+
+- **docker-compose.yml**: Coordinates two services:  
+  - **db** (PostgreSQL 13) initialized via `./db.sql`.  
+  - **web** (PHP 8.2 + Apache with pdo_pgsql) linked to `db`, exposing port 8080.  
+- **Dockerfile**: Base `php:8.2-apache`, installs `libpq-dev` and `pdo_pgsql`, copies `src/` to `/var/www/html/`.  
+- **db.sql**: SQL to auto-create the `visitors` table.  
+- **prepare-app.sh** & **remove-app.sh**: Bash scripts for Git-based deployment and cleanup on Plesk.  
+- **index.php**: Main page logic (connect, migrate, insert, count, render).  
+- **drop.php**: Drops the `visitors` table.
+
+---
+
+## Troubleshooting
+
+- **PostgreSQL connection error**: Ensure the `db` service is running; check logs:
+  ```bash
+  docker-compose logs db
+  ```
+- **Table not created**: Make sure `db.sql` is mounted under `/docker-entrypoint-initdb.d/` and that the `db_data` volume is empty (initialization only runs on a fresh volume).  
+- **Git push rejected**: Verify remote URL and credentials in `prepare-app.sh`.
