CakePHP 4 Using an app.php or app_local.php Variable in Components or Controllers

In your controller, add the following to access the configuration settings:

use Cake\Core\Configure;

Set your variable value in app.php or app_local.php

return [
   ...
   'MyConfig' => [
        'userid' => env('MYCONFIG_USERID', 'EXAMPLEUSERID'),
        'password' => env('MYCONFIG_PASSWORD', 'EXAMPLEPASSWORD'),
    ],
   ...
];

Then, you can read the variables, like the following example:

$userid = Configure::read('Myconfig.userid');
$password = Configure::read('Myconfig.password');
