Yaf_Config_Ini::get — Retrieve a configuration value
Retrieves a configuration value by name. Dot notation (e.g. database.host) can be used to access nested values. If name is omitted or null, the configuration object itself is returned.
nameThe configuration key, optionally using dot notation for nested access.
The value associated with name. Array values are wrapped in a Yaf_Config_Ini object. Returns null if the key does not exist, or the configuration object itself when name is null.
Example #1 Yaf_Config_Ini::get() example
<?php
/**
* Assume /etc/myapp/application.ini contains:
* [common]
* application.name = "MyApp"
* database.host = "localhost"
* database.port = 3306
*/
$config = new Yaf_Config_Ini('/etc/myapp/application.ini', 'common');
// Dot notation for nested access
echo $config->get('database.host'), "\n";
// Array values are wrapped in a Yaf_Config_Ini object
echo $config->get('database')->port, "\n";
// No argument: the configuration object itself is returned
echo $config->get()->application->name, "\n";
var_dump($config->get('missing.key'));
?>The above example will output something similar to:
localhost 3306 MyApp NULL
