# 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`.
