Code Review

This pull request introduces several optimizations and safety improvements across multiple PHP samples and Dockerfiles. Key updates include adding --no-install-recommends and cleaning up apt lists in Dockerfiles, refactoring PHP code to use safer null checks and isset() array access, handling uppercase formats in Parameter Manager, and updating the google/auth dependency. The reviewer recommended further optimizing the Docker builds by adding --no-interaction and --optimize-autoloader flags to the Composer commands to prevent interactive prompts and improve production performance.

It is recommended to run Composer with --no-interaction to prevent the build from hanging on interactive prompts, and --optimize-autoloader to optimize the autoloader for better performance in production environments.
