A trait that provides a set of static methods to manage configuration for classes that provide an adapter facade or need to have sets of configuration data registered and manipulated.
Implementing objects are expected to declare a static $_dsnClassMap
property.
config( string|array $key , array $config null )
This method can be used to define configuration adapters for an application or read existing configuration.
To change an adapter's configuration at runtime, first drop the adapter and then reconfigure it.
Adapters will not be constructed until the first operation is done.
Assuming that the class' name is Cache
the following scenarios are supported:
Reading config data back:
Cache::config('default');
Setting a cache engine up.
Cache::config('default', $settings);
Injecting a constructed adapter in:
Cache::config('default', $instance);
Configure multiple adapters at once:
Cache::config($arrayOfConfig);
$key
$config
optional null array|null
BadMethodCallException
configured( )
Returns an array containing the named configurations
array
drop( string $config )
Drops a constructed adapter.
If you wish to modify an existing configuration, you should drop it, change configuration and then re-add it.
If the implementing objects supports a $_registry
object the named configuration will also be unloaded from the registry.
$config
boolean
dsnClassMap( array $map null )
Returns or updates the DSN class map for this class
$map
optional null array
parseDsn( string $dsn )
Parses a DSN into a valid connection configuration
This method allows setting a DSN using formatting similar to that used by PEAR::DB. The following is an example of its usage:
$dsn = 'mysql://user:pass@localhost/database?'; $config = ConnectionManager::parseDsn($dsn); $dsn = 'Cake\Log\Engine\FileLog://?types=notice,info,debug&file=debug&path=LOGS'; $config = Log::parseDsn($dsn); $dsn = 'smtp://user:secret@localhost:25?timeout=30&client=null&tls=null'; $config = Email::parseDsn($dsn); $dsn = 'file:///?className=\My\Cache\Engine\FileEngine'; $config = Cache::parseDsn($dsn); $dsn = 'File://?prefix=myapp_cake_core_&serialize=true&duration=+2 minutes&path=/tmp/persistent/'; $config = Cache::parseDsn($dsn);
For all classes, the value of scheme
is set as the value of both the className
unless they have been otherwise specified.
Note that querystring arguments are also parsed and set as values in the returned configuration.
$dsn
array
