Lightweight plugin that displays essential server and environment information directly in the WordPress admin bar for administrators.

== Description ==

**Admin Bar Server Info** displays essential server and environment information directly in the WordPress admin bar.

The plugin is intentionally minimal and focused. It does not add settings pages, dashboard widgets, frontend output, or database storage. It simply shows key environment information at a glance for users with administrative permissions.

Displayed information includes:

**PHP Information:**
- PHP version (full version with architecture bits)
- PHP SAPI (Server API: mod_php, fpm, cgi, etc.)
- Operating system (Linux, Windows, Darwin, etc.)
- Max execution time
- Max upload size

**Memory Information:**
- Current memory usage and limit (with percentage)
- WordPress memory limit (WP_MEMORY_LIMIT)

**Server Information:**
- Server software (Apache, Nginx, LiteSpeed, IIS, Caddy, etc.)
- Database version (MySQL or MariaDB with version)
- Server IP address (with hostname)

**WordPress Information:**
- WordPress version

The information is visible only to users with the `manage_options` capability.

**Key characteristics:**
- Admin bar only - all information visible at a glance
- No configuration required - works immediately after activation
- No frontend output - admin area only
- No database tables or stored options
- No external requests - all data gathered locally
- Minimal CSS - only for admin bar styling (follows WordPress best practices)
- No JavaScript dependencies
- No tracking or data collection
- Developer-friendly format - compact and logically organized

1. Upload the `admin-bar-server-info` folder to the `/wp-content/plugins/` directory.
2. Activate the plugin through the “Plugins” menu in WordPress.
3. The server information will appear automatically in the admin bar for administrators.
