Properties

$_values

$_values : array

Array of values currently stored in Configure.

Type

array

$_hasIniSet

$_hasIniSet : boolean|null

Flag to track whether or not ini_set exists.

Type

boolean|null

Methods

write()

write(string|array  $config, mixed  $value = null) : boolean

Used to store a dynamic variable in Configure.

Usage:

Configure::write('One.key1', 'value of the Configure::One[key1]');
Configure::write(['One.key1' => 'value of the Configure::One[key1]']);
Configure::write('One', [
    'key1' => 'value of the Configure::One[key1]',
    'key2' => 'value of the Configure::One[key2]'
]);

Configure::write([
    'One.key1' => 'value of the Configure::One[key1]',
    'One.key2' => 'value of the Configure::One[key2]'
]);

Parameters

string|array $config

The key to write, can be a dot notation value. Alternatively can be an array containing key(s) and value(s).

mixed $value

Value to set for var

Returns

boolean —

True if write was successful

read()

read(string|null  $var = null, mixed  $default = null) : mixed

Used to read information stored in Configure. It's not possible to store `null` values in Configure.

Usage:

Configure::read('Name'); will return all values for Name
Configure::read('Name.key'); will return only the value of Configure::Name[key]

Parameters

string|null $var

Variable to obtain. Use '.' to access array elements.

mixed $default

The return value when the configure does not exist

Returns

mixed —

Value stored in configure, or null.

check()

check(string  $var) : boolean

Returns true if given variable is set in Configure.

Parameters

string $var

Variable name to check for

Returns

boolean —

True if variable is there

readOrFail()

readOrFail(string  $var) : mixed

Used to get information stored in Configure. It's not possible to store `null` values in Configure.

Acts as a wrapper around Configure::read() and Configure::check(). The configure key/value pair fetched via this method is expected to exist. In case it does not an exception will be thrown.

Usage:

Configure::readOrFail('Name'); will return all values for Name
Configure::readOrFail('Name.key'); will return only the value of Configure::Name[key]

Parameters

string $var

Variable to obtain. Use '.' to access array elements.

Throws

\RuntimeException

if the requested configuration is not set.

Returns

mixed —

Value stored in configure.

delete()

delete(string  $var) : void

Used to delete a variable from Configure.

Usage:

Configure::delete('Name'); will delete the entire Configure::Name
Configure::delete('Name.key'); will delete only the Configure::Name[key]

Parameters

string $var

the var to be deleted

consumeOrFail()

consumeOrFail(string  $var) : mixed

Used to consume information stored in Configure. It's not possible to store `null` values in Configure.

Acts as a wrapper around Configure::consume() and Configure::check(). The configure key/value pair consumed via this method is expected to exist. In case it does not an exception will be thrown.

Parameters

string $var

Variable to consume. Use '.' to access array elements.

Throws

\RuntimeException

if the requested configuration is not set.

Returns

mixed —

Value stored in configure.

consume()

consume(string  $var) : array|string|null

Used to read and delete a variable from Configure.

This is primarily used during bootstrapping to move configuration data out of configure into the various other classes in CakePHP.

Parameters

string $var

The key to read and remove.

Returns

array|string|null

config()

config(string  $name, \Cake\Core\Configure\ConfigEngineInterface  $engine) : void

Add a new engine to Configure. Engines allow you to read configuration files in various formats/storage locations. CakePHP comes with two built-in engines PhpConfig and IniConfig. You can also implement your own engine classes in your application.

To add a new engine to Configure:

Configure::config('ini', new IniConfig());

Parameters

string $name

The name of the engine being configured. This alias is used later to read values from a specific engine.

\Cake\Core\Configure\ConfigEngineInterface $engine

The engine to append.

configured()

configured(string|null  $name = null) : array|boolean

Gets the names of the configured Engine objects.

Checking if a specific engine has been configured with this method is deprecated. Use Configure::isConfigured() instead.

Parameters

string|null $name

Engine name.

Returns

array|boolean —

Array of the configured Engine objects, bool for specific name.

isConfigured()

isConfigured(string  $name) : boolean

Returns true if the Engine objects is configured.

Parameters

string $name

Engine name.

Returns

boolean

drop()

drop(string  $name) : boolean

Remove a configured engine. This will unset the engine and make any future attempts to use it cause an Exception.

Parameters

string $name

Name of the engine to drop.

Returns

boolean —

Success

load()

load(string  $key, string  $config = 'default', boolean  $merge = true) : boolean

Loads stored configuration information from a resource. You can add config file resource engines with `Configure::config()`.

Loaded configuration information will be merged with the current runtime configuration. You can load configuration files from plugins by preceding the filename with the plugin name.

Configure::load('Users.user', 'default')

Would load the 'user' config file using the default config engine. You can load app config files by giving the name of the resource you want loaded.

Configure::load('setup', 'default');

If using default config and no engine has been configured for it yet, one will be automatically created using PhpConfig

Parameters

string $key

name of configuration resource to load.

string $config

Name of the configured engine to use to read the resource identified by $key.

boolean $merge

if config files should be merged instead of simply overridden

Returns

boolean —

False if file not found, true if load successful.

dump()

dump(string  $key, string  $config = 'default', array  $keys = array()) : boolean

Dump data currently in Configure into $key. The serialization format is decided by the config engine attached as $config. For example, if the 'default' adapter is a PhpConfig, the generated file will be a PHP configuration file loadable by the PhpConfig.

Usage

Given that the 'default' engine is an instance of PhpConfig. Save all data in Configure to the file my_config.php:

Configure::dump('my_config', 'default');

Save only the error handling configuration:

Configure::dump('error', 'default', ['Error', 'Exception'];

Parameters

string $key

The identifier to create in the config adapter. This could be a filename or a cache key depending on the adapter being used.

string $config

The name of the configured adapter to dump data with.

array $keys

The name of the top-level keys you want to dump. This allows you save only some data stored in Configure.

Throws

\Cake\Core\Exception\Exception

if the adapter does not implement a dump method.

Returns

boolean —

Success

version()

version() : string

Used to determine the current version of CakePHP.

Usage

Configure::version();

Returns

string —

Current version of CakePHP

store()

store(string  $name, string  $cacheConfig = 'default', array|null  $data = null) : boolean

Used to write runtime configuration into Cache. Stored runtime configuration can be restored using `Configure::restore()`. These methods can be used to enable configuration managers frontends, or other GUI type interfaces for configuration.

Parameters

string $name

The storage name for the saved configuration.

string $cacheConfig

The cache configuration to save into. Defaults to 'default'

array|null $data

Either an array of data to store, or leave empty to store all values.

Returns

boolean —

Success

restore()

restore(string  $name, string  $cacheConfig = 'default') : boolean

Restores configuration data stored in the Cache into configure. Restored values will overwrite existing ones.

Parameters

string $name

Name of the stored config file to load.

string $cacheConfig

Name of the Cache configuration to read from.

Returns

boolean —

Success.

clear()

clear() : boolean

Clear all values stored in Configure.

Returns

boolean —

success.

_getEngine()

_getEngine(string  $config) : \Cake\Core\Configure\ConfigEngineInterface|false

Get the configured engine. Internally used by `Configure::load()` and `Configure::dump()` Will create new PhpConfig for default if not configured yet.

Parameters

string $config

The name of the configured adapter

Returns

\Cake\Core\Configure\ConfigEngineInterface|false —

Engine instance or false
