setLastErrorsource public

setLastError( integer $errNum , string $errStr )

Set the last error.

Parameters

integer $errNum

Error code

string $errStr

Error string

writesource public

write( string $data )

Write data to the socket.

Parameters

string $data

The data to write to the socket

Returns

boolean
Success

_configDeletesource protected

_configDelete( string $key )

Delete a single config key

Parameters

string $key

Key to delete.

Throws

Cake\Core\Exception\Exception
if attempting to clobber existing config

_configReadsource protected

_configRead( string|null $key )

Read a config variable

Parameters

string|null $key

Key to read.

Returns

mixed
mixed

_configWritesource protected

_configWrite( string|array $key , mixed $value , boolean|string $merge false )

Write a config variable

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

configsource public

config( string|array|null $key null , mixed|null $value null , boolean $merge true )

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']);

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.

configShallowsource 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

mixed
$this The object itself.
