# Technology Stack

**Analysis Date:** 2026-05-05

## Languages

**Primary:**
- PHP 7.4+ - All backend logic, templates, AJAX handlers
- HTML (via PHP templates) - Page rendering, admin UI

**Secondary:**
- JavaScript / jQuery - Frontend interactivity
- SCSS - Admin and frontend styling (compiled to CSS)
- CSS - Compiled output + Bootstrap overrides

## Runtime

**Environment:**
- PHP 7.4+ on Apache web server
- Apache with `mod_rewrite` enabled (required for URL routing via `.htaccess`)
- MySQL 5.7+ - Primary database

**Package Manager:**
- None — all dependencies manually vendored in `libraries/` and `plugins/` directories
- No Composer, npm, or yarn

## Frameworks

**Core:**
- Custom CMS framework (cmsPro) — no external PHP framework (no Laravel, Symfony, etc.)
- Medoo ORM 1.x — database abstraction layer (`libraries/medoo/medoo.php`)
- Bootstrap 4.1.3 (`libraries/bootstrap-4.1.3/`) and Bootstrap 5.0 (`libraries/bootstrap-5.0/`)

**Testing:**
- None detected — no PHPUnit, Jest, or any test runner configured

**Build/Dev:**
- Live Sass Compiler (VS Code extension) — compiles SCSS to CSS
- No webpack, Vite, or build pipeline
- SCSS output directive at top of files: `// out: ../style-css/style.css, compress: true`

## Key Dependencies

**Critical:**
- Medoo ORM — all database operations (`libraries/medoo/medoo.php`)
- PHPMailer — SMTP email sending (`libraries/phpmailer/class.phpmailer.php`, `class.smtp.php`)
- jQuery 1.11.1 (admin) / 2.1.4 (login page CDN) — frontend interactivity
- CKEditor — rich text editing in admin panel (`libraries/ckeditor/`)

**Admin UI Libraries:**
- Grid library (gdb) — data table component (`libraries/grid/`)
- Select2 — enhanced dropdowns (`plugins/select2/`)
- FancyBox — lightbox (`plugins/fancybox/`)
- File Uploader — file upload UI (`plugins/fileuploader/`)
- Swiper — carousels (`libraries/swiper/`)

**Frontend Libraries:**
- Font Awesome 6.1.1 — icons (`libraries/font-awesome-6.1.1/`)
- Lozad — lazy image loading (`libraries/jquery/lozad.js`)
- jsCloudimage360 — 360° image viewer (`libraries/jsCloudimage360/`)
- Moment.js — date formatting (`libraries/framework/vendor/plugins/moment/`)
- DateRangePicker — date inputs (`libraries/framework/vendor/plugins/daterange/`)

## Configuration

**Environment:**
- No `.env` files — configuration hardcoded in `config.php`
- `config.php` — database host, user, password, database name (credentials in plain text)
- `admin/ip.conf` — optional IP whitelist for admin panel access
- Global site settings stored in `pp_settings` database table

**Build:**
- `.vscode/settings.json` — VS Code Live Sass Compiler config
- No tsconfig, no webpack.config, no vite.config

## Platform Requirements

**Development:**
- Apache + PHP 7.4+ + MySQL 5.7+
- VS Code with Live Sass Compiler extension for SCSS editing
- FTP access configured in `.vscode/sftp.json` / `.vscode/ftp-kr.json`

**Production:**
- Shared hosting at `serwer1574995.home.pl` (inferred from `config.php`)
- Apache `.htaccess` URL rewriting
- No Docker, no CI/CD pipeline detected
