Configuration access helper and environment manager

Usage


//build config
$config = array();
$config['test1'] = 'test';
$config['test2']['sec'] = 'test';
$config['test3']['sec'] = 'test2';

//load config
Config::setConfig($config); unset($config);

//set an additional
Config::set('test2.newsec',null,'testvalue');

//get options
$test = Config::get('test1');
$test2 = Config::get('test2.sec');
$test3 = Config::get('test2.newsec');

//get merged
$db = Config::getMerged('sec'); //will return test2

Singleton

Config operates with an internal singleton even though all the methods are static.

To retrieve the singleton use the following

//use the clone keyword to actually copy the object (this is optional)
$inst = clone Config::_get();

//load up a new temporary config
Config::setConfig($newconfig);

//restore the old config
Config::$inst = clone $inst; unset($inst);

Reference

(object) _get()

Returns the current singleton (will create one if it doesnt exist)

(void) setConfig($config)

Will set the passed array to the main config This will merge with the existing config

(void) resetConfig($config)

Resets the internal config registry

(void) dumpConfig($config)

var_dumps the internal config Note: use output buffers to capture this

(void) setDefaults($config)

Made to be used by packages will set the passed config below the internal config Example:

self::_get()->config = array_merge($config,self::_get()->config);

This allows userspace overrides to remain in affect regardless of registration time.

(mixed) set($sec,$name,$value)

Sets a value in the config

  • $sec config section (can be an MDA key) NULL for none
  • $name config name (can be an MDA key) NULL for none
  • $value Value to be set Returns the value to be set

(bool) exists($sec,$name=null)

Check if a value exists

  • $sec config section (can be an MDA key) NULL for none
  • $name config name (can be an MDA key) NULL for none

(mixed) get($sec=null,$name=null)

Get a value from the confi structure

  • $sec config section (can be an MDA key) NULL for none
  • $name config name (can be an MDA key) NULL for none

(mixed) getMerged($sec,$name=null)

Get a merged value from the config tree Consider the following config structure

//full tree
$config['db']['driver'] = 'mysql';
$config['admin']['db']['driver'] = 'sqlite3';

Config::setConfig($config);
$val = Config::getMerged('admin','db.driver'); //returns 'sqllite'

//shorthand tree
$config['db']['driver'] = 'mysql';

Config::setConfig($config);
$val = Config::getMerged('admin','db.driver'); //returns 'mysql'

The idea is to retrieve a section from a subroot and gracefully look upstream.

  • $sec config section (can be an MDA key) NULL for none
  • $name config name (can be an MDA key) NULL for none
