# EXAMPLE: FastCGI Plugin with PHP-FPM
# ==============================================================================
#
# WHAT THIS DEMONSTRATES:
# - PHP-FPM configuration with FastCGI protocol (proto: fcgi)
# - FastCGI plugin for PHP environment variable configuration
# - TCP connection to PHP-FPM on port 9000
# - PATH_INFO support for RESTful routing
# - Custom document root and index file configuration
#
#
# HOW TO START:
# ```bash
# docker compose -f docker-compose-php-fpm.yml up -d
# ```
#
# HOW TO VERIFY IT'S WORKING:
# ```bash
# # Test main page
# curl -k -H "Host: phpapp.local"  http://127.0.0.1/
# # Expected: 200 OK with PHP environment info
#
# # Test PHP info page
# -k -H "Host: phpapp.local"  http://127.0.0.1/info.php
# # Expected: phpinfo() output
#
# # Test PATH_INFO routing
# -k -H "Host: phpapp.local"  http://127.0.0.1/test-path-info.php/users/123
# # Expected: PATH_INFO=/users/123
#
# # View HAProxy stats
# # URL: http://localhost:1936
# # Username: admin
# # Password: password
# ```
#
# CLEAN UP:
# ```bash
# docker compose -f docker-compose-php-fpm.yml down
# ```
