-# 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`.
