Yaf_Config_Ini::offsetUnset 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');

// Yaf_Config_Ini is read-only: a warning is emitted, nothing is removed
unset($config['database']);
