_format() 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

- array $context optional []
- Additional logging information for the message.
Returns
Methods used from Cake\Core\InstanceConfigTrait
_configDelete() protected ¶
_configDelete( string $key )
Deletes a single config key.
Parameters
- string $key
- Key to delete.
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.
Parameters
- string|array $key
- Key to write to.
- mixed $value
- Value to write.
- boolean|string $merge optional false
True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Throws
config() 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
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 )
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 $value optional null
- The value to set.
Returns
$this
getConfig() 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 $key optional null
- The key to get or null for the whole config.
- mixed $default optional null
- The return value when the key does not exist.
Returns
Config value being read.
setConfig() 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:

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.
