Não consigo acessar localhost:8080/listar-cursos.php

Não consigo acessar a página "Esta página não está funcionando". Faço a instalação do composer:

C:\Users\PC\Downloads\gerenciador-de-cursos>composer install
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Nothing to install, update or remove

17 packages you are using are looking for funding.

Depois dou o localhost:

C:\Users\PC\Downloads\gerenciador-de-cursos>php -S localhost:8080 -t public
[Thu Dec 10 18:14:17 2020] PHP 8.0.0 Development Server (http://localhost:8080) started

Dai quando vou acessar a página dá nisso:

C:\Users\PC\Downloads\gerenciador-de-cursos>php -S localhost:8080 -t public

E mais um monte de código em baixo.
