# Class **Phalcon\Config\Adapter\Php**[](# "永久链接至标题") *extends* class [*Phalcon\Config*](#) *implements* Countable, ArrayAccess Reads php files and converts them to Phalcon\Config objects. Given the next configuration file: ~~~ <?php <?php return array( 'database' => array( 'adapter' => 'Mysql', 'host' => 'localhost', 'username' => 'scott', 'password' => 'cheetah', 'dbname' => 'test_db' ), 'phalcon' => array( 'controllersDir' => '../app/controllers/', 'modelsDir' => '../app/models/', 'viewsDir' => '../app/views/' )); You can read it as follows: ~~~ ~~~ <?php $config = new Phalcon\Config\Adapter\Php("path/config.php"); echo $config->phalcon->controllersDir; echo $config->database->username; ~~~ ### Methods[](# "永久链接至标题") public **__construct** (*unknown* $filePath) Phalcon\Config\Adapter\Php constructor public **offsetExists** (*unknown* $index) inherited from Phalcon\Config Allows to check whether an attribute is defined using the array-syntax ~~~ <?php var_dump(isset($config['database'])); ~~~ public **get** (*unknown* $index, [*unknown* $defaultValue]) inherited from Phalcon\Config Gets an attribute from the configuration, if the attribute isn't defined returns null If the value is exactly null or is not defined the default value will be used instead ~~~ <?php echo $config->get('controllersDir', '../app/controllers/'); ~~~ public **offsetGet** (*unknown* $index) inherited from Phalcon\Config Gets an attribute using the array-syntax ~~~ <?php print_r($config['database']); ~~~ public **offsetSet** (*unknown* $index, *unknown* $value) inherited from Phalcon\Config Sets an attribute using the array-syntax ~~~ <?php $config['database'] = array('type' => 'Sqlite'); ~~~ public **offsetUnset** (*unknown* $index) inherited from Phalcon\Config Unsets an attribute using the array-syntax ~~~ <?php unset($config['database']); ~~~ public **merge** (*unknown* $config) inherited from Phalcon\Config Merges a configuration into the current one ~~~ <?php $appConfig = new \Phalcon\Config(array('database' => array('host' => 'localhost'))); $globalConfig->merge($config2); ~~~ public **toArray** () inherited from Phalcon\Config Converts recursively the object to an array ~~~ <?php print_r($config->toArray()); ~~~ public **count** () inherited from Phalcon\Config Returns the count of properties set in the config ~~~ <?php print count($config); ~~~ or ~~~ <?php print $config->count(); ~~~ public static **__set_state** (*unknown* $data) inherited from Phalcon\Config Restores the state of a Phalcon\Config object final protected *Config merged config***_merge** (*Config* $config, [*unknown* $instance]) inherited from Phalcon\Config Helper method for merge configs (forwarding nested config instance) | - [索引](# "总目录") - [下一页](# "Class Phalcon\Config\Adapter\Yaml") | - [上一页](# "Class Phalcon\Config\Adapter\Json") | - [API Indice](#) »
