How remove a custom settings from $sugar_config

Question

I create custom setting

  $configurator = new Configurator();
  $configurator->loadConfig(); 
  $configurator->config['test_value'] = 'test value'; 
  $configurator->saveConfig(); // save changes

How I can remove it?

Answer 1

Never used it, but maybe:

$configurator->config['test_value'] = null;
$configurator->saveConfig();

Or:

unset($configurator->config['test_value']);  
$configurator->saveConfig();
