When using Composer in a production environment, you need to pay attention to safety, stability and performance. 1. Use composerinstall-no-dev to reduce unnecessary development dependencies and reduce online environment risks; 2. Always submit and rely on composer.lock files to ensure version consistency, and avoid using updates during deployment; 3. Optional configuration platform-check=false ignores platform differences warnings, which is suitable for building packaging scenarios; 4. Enable APCU to accelerate automatic loading to improve performance, especially suitable for high concurrency services, while paying attention to namespace uniqueness to avoid cache conflicts.

If the vendor directory is successfully created and the dependency is downloaded, it means that Composer is fully available. If the above steps fail, you may need to check whether PHP has been installed globally or adjusted system path settings.

Methods to manage database state in Laravel tests include using RefreshDatabase, selective seeding of data, careful use of transactions, and manual cleaning if necessary. 1. Use RefreshDatabasetrait to automatically migrate the database structure to ensure that each test is based on a clean database; 2. Use specific seeds to fill the necessary data and generate dynamic data in combination with the model factory; 3. Use DatabaseTransactionstrait to roll back the test changes, but pay attention to its limitations; 4. Manually truncate the table or reseed the database when it cannot be automatically cleaned. These methods are flexibly selected according to the type of test and environment to ensure the reliability and efficiency of the test.
