Why does 'php artisan serve' fail with 'Address already in use'?

You run php artisan serve but get the error Address already in use. What is the most likely cause?

A The Laravel project is missing the .env file.

B The database connection is not configured.

C The PHP version is incompatible with Laravel.

D Another process is already using the default port 8000.

💡 Hint

Think about network ports and running servers.

The error means the default port 8000 is busy because another server or process is already using it.

What is the output of this Artisan command sequence?

Given a Laravel project with no migrations run yet, what will be the output after running these commands in order?

php artisan migrate:status
php artisan migrate
php artisan migrate:status

A First shows error, second runs migrations, third shows error.

B First shows all migrations as 'Yes', second runs migrations, third shows all as 'No'.

C First shows all migrations as 'No', second runs migrations, third shows all as 'Yes'.

D First shows empty list, second does nothing, third shows empty list.

💡 Hint

Think about migration status before and after running migrations.

Before running migrations, migrate:status shows all migrations as not run ('No'). After running php artisan migrate, the migrations are applied. Running migrate:status again shows all migrations as run ('Yes').
