What are the best practices for handling dependencies like Composer in PHP projects, especially when dealing with server limitations?

When dealing with server limitations in PHP projects, it's essential to optimize the handling of dependencies like Composer. One best practice is to regularly update Composer and dependencies to ensure compatibility and security. Additionally, you can use Composer's `--no-dev` flag during deployment to exclude development dependencies and reduce server load.

// Update Composer and dependencies
composer self-update
composer update

// Install dependencies without dev packages
composer install --no-dev
