Throws
_configRead() protected ¶
_configRead( string|null $key )
Reads a config key.
Parameters
- string|null $key
- Key to read.
Returns
_configWrite() protected ¶
_configWrite( string|array $key , mixed $value , boolean|string $merge false )
Writes a config key.

Gets/Sets the config.
Usage
Reading the whole config:

Reading a nested value:
$this->config('some.nested.key');
Setting a specific value:
$this->config('key', $value);
Setting a nested value:

Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);
Deprecated
Parameters
- string|array|null $key optional null
- The key to get/set, or a complete array of configs.
- mixed|null $value optional null
- The value to set.
- boolean $merge optional true
- Whether to recursively merge or overwrite existing config, defaults to true.
Returns
Config value being read, or the object itself on write operations.
Throws
configShallow() public ¶
configShallow( string|array $key , mixed|null $value null )

a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->configShallow('key', $value);
Setting a nested value:
$this->configShallow('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);
