Admin Bar Server Info displays essential server and environment information in a convenient dropdown menu on 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 in an organized dropdown menu accessible with one click from the admin bar 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) 
– Disk space (free/total with percentage used)
WordPress Information: 
– WordPress version
The information is visible only to users with the <code>manage_options</code> capability.
Key characteristics: 
– Dropdown menu – all information organized and accessible with one click 
– Icon-only display in admin bar for space efficiency 
– 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 
– Fully responsive – adapts to mobile screens
