💡 Hint

Common Mistakes

Using a wrong config key like 'database.connections.mysql' instead of 'app.name'.

Forgetting to put the key as a string.

The config() helper accesses configuration values by their key. To get the application name, use 'app.name'.

💡 Hint

Common Mistakes

Not using quotes around the driver name.

Using a driver name that is not supported.

To change a config value at runtime, pass an array with the key and new value to config(). Here, we set 'cache.default' to 'redis'.

Fix the error in accessing the database host from config.

$dbHost = config('[1]');
// Expected to get '127.0.0.1' from config/database.php

Drag options to blanks, or click blank then click option'

Adatabase.host

Bconnections.mysql.host

Cdatabase.mysql.host

Ddatabase.connections.mysql.host

💡 Hint

Common Mistakes

Using 'database.host' which does not exist.

Using incomplete keys missing 'connections.mysql'.

The correct key to access the MySQL host is 'database.connections.mysql.host' because the config file is nested that way.

config(['[2]' => 'smtp']);

Drag options to blanks, or click blank then click option'

Cmail.mailer

Dmail.transport

💡 Hint

Common Mistakes

Using 'mail.driver' which is not the correct key in Laravel 8+.

Using different keys for get and set.

The mail driver is accessed and set using the key 'mail.default' in Laravel config.

5fill in blank

hard

Fill all three blanks to create a config array with keys 'app.env', 'app.debug', and 'app.url'.

Laravel

$settings = [
  '[1]' => config('[2]'),
  '[3]' => config('app.url')
];

Drag options to blanks, or click blank then click option'

Aapp.env

Bapp.debug

Attempts:

💡 Hint

Common Mistakes

Mixing keys and values incorrectly.

Using keys that don't exist in config.

The array keys and config keys must match. 'app.env' and 'app.debug' are used to get environment and debug settings, and 'app.url' is used directly.
