StaticConfigTrait
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.
Table of Contents
Properties
- $_config : array<string, mixed>
- Configuration sets.
Methods
- configured() : array<string|int, string>
- Returns an array containing the named configurations
- drop() : bool
- Drops a constructed adapter.
- getConfig() : mixed|null
- Reads existing configuration.
- getConfigOrFail() : mixed
- Reads existing configuration for a specific key.
- getDsnClassMap() : array<string, string>
- Returns the DSN class map for this class.
- parseDsn() : array<string, mixed>
- Parses a DSN into a valid connection configuration
- setConfig() : void
- This method can be used to define configuration adapters for an application.
- setDsnClassMap() : void
- Updates the DSN class map for this class.

Methods
configured()
Returns an array containing the named configurations
public
static configured() : array<string|int, string>
Return values
array<string|int, string> —Array of configurations.
drop()
Drops a constructed adapter.
public
static drop(string $config) : bool
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.
Parameters
- $config : string
-
An existing configuration you wish to remove.
Return values
bool —Success of the removal, returns false when the config does not exist.
getConfig()
Reads existing configuration.
public
static getConfig(string $key) : mixed|null
Parameters
- $key : string
-
The name of the configuration.
Return values
mixed|null —Configuration data at the named key or null if the key does not exist.
getConfigOrFail()
Reads existing configuration for a specific key.
public
static getConfigOrFail(string $key) : mixed
The config value for this key must exist, it can never be null.
Parameters
- $key : string
-
The name of the configuration.
Tags
Return values
mixed —Configuration data at the named key.
getDsnClassMap()
Returns the DSN class map for this class.
public
static getDsnClassMap() : array<string, string>
Tags
Return values
array<string, string>parseDsn()
Parses a DSN into a valid connection configuration
public
static parseDsn(string $dsn) : array<string, mixed>
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.
Parameters
- $dsn : string
-
The DSN string to convert to a configuration array
Tags
Return values
array<string, mixed> —The configuration array to be stored after parsing the DSN
setConfig()
This method can be used to define configuration adapters for an application.
public
static setConfig(array<string, mixed>|string $key[, mixed $config = null ]) : void
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.
Usage
Assuming that the class' name is Cache the following scenarios
are supported:
Setting a cache engine up.
Cache::setConfig('default', $settings);
Injecting a constructed adapter in:
Cache::setConfig('default', $instance);
Configure multiple adapters at once:
Cache::setConfig($arrayOfConfig);
Parameters
- $key : array<string, mixed>|string
-
The name of the configuration, or an array of multiple configs.
- $config : mixed = null
-
Configuration value. Generally an array of name => configuration data for adapter.
Tags
setDsnClassMap()
Updates the DSN class map for this class.
public
static setDsnClassMap(array<string, string> $map) : void
Parameters
- $map : array<string, string>
-
Additions/edits to the class map to apply.
