Setting User-Provided Values
Once your schema has been defined you can apply user-provided configuration values. There are two methods available to do this:
set($key, $value)- Define a single valuemerge($values)- Define multiple values in one call
Example
Let’s take the following configuration as an example:
use League\Config\Configuration;
use Nette\Schema\Expect;
$config = new Configuration([
'debug_mode' => Expect::bool()->required(),
'database' => Expect::structure([
'driver' => Expect::anyOf('mysql', 'postgresql', 'sqlite')->required(),
'host' => Expect::string()->default('localhost'),
'port' => Expect::int()->min(1)->max(65535),
'ssl' => Expect::bool(),
'database' => Expect::string()->required(),
'username' => Expect::string()->required(),
'password' => Expect::string()->nullable(),
]),
'logging' => Expect::structure([
'enabled' => Expect::bool()->default($_ENV['DEBUG'] == true),
'file' => Expect::string()->deprecated("use logging.path instead"),
'path' => Expect::string()->assert(function ($path) { return \is_writeable($path); })->required(),
]),
]);
You could set everything at once like this:
$config->merge([
'debug_mode' => false,
'database' => [
'driver' => 'mysql',
'port' => 3306,
'database' => 'myapp',
'username' => 'myapp_user',
'password' => 'hunter2',
],
'logging' => [
'enabled' => true,
'file' => '/var/log/myapp.log',
],
]);
Maybe that array of data comes from a different file or method:
$config->merge(getUserConfig());
// or
$config->merge(json_decode(file_get_contents('database.json'), true));
Options can also be set individually, if needed:
// Load config from a json file...
$config->merge(json_decode(file_get_contents('database.json'), true));
// But override a certain setting
$config->set('debug_mode', false);
