Method Summary

  • __destruct() public
    Closes the logger connection

  • log() public

Method Detail

__destruct()source public

__destruct( )

Closes the logger connection

_open()source protected

_open( string $ident , integer $options , integer $facility )

Extracts the call to openlog() in order to run unit tests on it. This function will initialize the connection to the system logger

Parameters

string $ident
the prefix to add to all messages logged
integer $options
the options flags to be used for logged messages
integer $facility
the stream or facility to log to

_write()source protected

_write( integer $priority , string $message )

Extracts the call to syslog() in order to run unit tests on it. This function will perform the actual write in the system logger

Parameters

integer $priority
Message priority.
string $message
Message to log.

Returns

boolean

log()source public

log( string $level , string $message , array $context [] )

Writes a message to syslog

Map the $level back to a LOG_ constant value, split multi-line messages into multiple log messages, pass all messages through the format defined in the configuration

Parameters

string $level
The severity level of log you are making.
string $message
The message you want to log.
array $context optional []
Additional information about the logged message

Returns

boolean
success of write.

__construct()source public

__construct( array $config [] )

__construct method

Parameters

array $config optional []
Configuration array

_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 $context optional []
Additional logging information for the message.

Returns

string

levels()source public

levels( )

Get the levels this logger is interested in.

Returns

array

scopes()source public

scopes( )

Get the scopes this logger is interested in.

Returns

array

Methods 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\Exception
if 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 $merge optional false

True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.

Throws

Cake\Core\Exception\Exception
if 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 $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

mixed
Config value being read, or the object itself on write operations.

Throws

Cake\Core\Exception\Exception
When 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->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']);

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()source public

getConfig( string|null $key 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');

Parameters

string|null $key optional null
The key to get or null for the whole config.

Returns

mixed
Config 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

Properties detail

$_defaultConfigsource

protected array

Default config for this class

By default messages are formatted as: level: message

To override the log format (e.g. to add your own info) define the format key when configuring this logger

If you wish to include a prefix to all messages, for instance to identify the application or the web server, then use the prefix option. Please keep in mind the prefix is shared by all streams using syslog, as it is dependent of the running process. For a local prefix, to be used only by one stream, you can use the format key.

Example:

Log::config('error', ]
     'engine' => 'Syslog',
     'levels' => ['emergency', 'alert', 'critical', 'error'],
     'format' => "%s: My-App - %s",
     'prefix' => 'Web Server 01'
 ]);
[
    'levels' => [],
    'scopes' => [],
    'format' => '%s: %s',
    'flag' => LOG_ODELAY,
    'prefix' => '',
    'facility' => LOG_USER
]

$_levelMapsource

protected int[]

Used to map the string names back to their LOG_* constants

[
    'emergency' => LOG_EMERG,
    'alert' => LOG_ALERT,
    'critical' => LOG_CRIT,
    'error' => LOG_ERR,
    'warning' => LOG_WARNING,
    'notice' => LOG_NOTICE,
    'info' => LOG_INFO,
    'debug' => LOG_DEBUG
]

$_opensource

protected boolean

Whether the logger connection is open or not

false
