_format()source protected
_format( mixed $data , array $context [] )
Converts to string the provided data so it can be logged. The context can optionally be used by log engines to interpolate variables or add additional info to the logged message.
Parameters
- mixed
$data - The data to be converted to string and logged.
- array
$contextoptional [] - Additional logging information for the message.
Returns
stringMethods used from Cake\Core\InstanceConfigTrait
_configDelete()source protected
_configDelete( string $key )
Deletes a single config key.
Parameters
- string
$key - Key to delete.
Throws
Cake\Core\Exception\Exceptionif attempting to clobber existing config
_configRead()source protected
_configRead( string|null $key )
Reads a config key.
Parameters
- string|null
$key - Key to read.
Returns
mixed_configWrite()source protected
_configWrite( string|array $key , mixed $value , boolean|string $merge false )
Writes a config key.
Parameters
- string|array
$key - Key to write to.
- mixed
$value - Value to write.
- boolean|string
$mergeoptional false True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Throws
Cake\Core\Exception\Exceptionif attempting to clobber existing config
config()source public
config( string|array|null $key null , mixed|null $value null , boolean $merge true )
Gets/Sets the config.
Usage
Reading the whole config:
$this->config();
Reading a specific value:
$this->config('key'); Reading a nested value:
$this->config('some.nested.key'); Setting a specific value:
$this->config('key', $value); Setting a nested value:
$this->config('some.nested.key', $value); Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);
Deprecated
3.4.0 use setConfig()/getConfig() instead.Parameters
- string|array|null
$keyoptional null - The key to get/set, or a complete array of configs.
- mixed|null
$valueoptional null - The value to set.
- boolean
$mergeoptional true - Whether to recursively merge or overwrite existing config, defaults to true.
Returns
mixedConfig value being read, or the object itself on write operations.
Throws
Cake\Core\Exception\ExceptionWhen trying to set a key that is invalid.
configShallow()source public
configShallow( string|array $key , mixed|null $value null )
Merge provided config with existing config. Unlike config() which does 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']);
Parameters
- string|array
$key - The key to set, or a complete array of configs.
- mixed|null
$valueoptional null - The value to set.
Returns
$this
getConfig()source public
getConfig( string|null $key null , mixed $default null )
Returns the config.
Usage
Reading the whole config:
$this->getConfig();
Reading a specific value:
$this->getConfig('key'); Reading a nested value:
$this->getConfig('some.nested.key'); Reading with default value:
$this->getConfig('some-key', 'default-value'); Parameters
- string|null
$keyoptional null - The key to get or null for the whole config.
- mixed
$defaultoptional null - The return value when the key does not exist.
Returns
mixedConfig value being read.
setConfig()source public
setConfig( string|array $key , mixed|null $value null , boolean $merge true )
Sets the config.
Usage
Setting a specific value:
$this->setConfig('key', $value); Setting a nested value:
$this->setConfig('some.nested.key', $value); Updating multiple config settings at the same time:
$this->setConfig(['one' => 'value', 'another' => 'value']);
Parameters
- string|array
$key - The key to set, or a complete array of configs.
- mixed|null

Default config for this class
-
levelsstring or array, levels the engine is interested in -
scopesstring or array, scopes the engine is interested in -
fileLog file name -
pathThe path to save logs on. -
sizeUsed to implement basic log file rotation. If log file size reaches specified size the existing file is renamed by appending timestamp to filename and new log file is created. Can be integer bytes value or human readable string values like '10MB', '100KB' etc. -
rotateLog files are rotated specified times before being removed. If value is 0, old versions are removed rather then rotated. -
maskA mask is applied when log files are created. Left empty no chmod is made.
