cakephp upgrade 2.xx to 3.x

Question

Deprecated: PHP configuration files like "app.php" should not set $config . Instead return an array. - C:\\composer\\upgrade\\vendor\\cakephp\\cakephp\\src\\Core\\Configure.php, line: 343
You can disable deprecation warnings by setting Error.errorLevel to E_ALL & ~E_USER_DEPRECATED in your config/app.php. in C:\\composer\\upgrade\\vendor\\cakephp\\cakephp\\src\\Core\\functions.php on line 311
Exception: If config is null, key must be an array. in [C:\\composer\\upgrade\\vendor\\cakephp\\cakephp\\src\\Core\\StaticConfigTrait.php, line 79]

I just follow the tools. How to remove the error?

Answer 1

Very simply, as the error message indicates, you need to return an array instead of setting $config . Change

$config = [

to

return [
