read(string $key = 'debug')

Used to read configuration data from the application. Defaults to CakePHP’s important debug value. If a key is supplied, the data is returned. Using our examples from write() above, we can read that data back:

Configure::read('Company.name');    //yields: 'Pizza, Inc.'
Configure::read('Company.slogan');  //yields: 'Pizza for your body and soul'
 
Configure::read('Company');
 
//yields: 
array('name' => 'Pizza, Inc.', 'slogan' => 'Pizza for your body and soul');

1. Configure::read('Company.name'); //yields: 'Pizza, Inc.'
2. Configure::read('Company.slogan'); //yields: 'Pizza for your body and soul'
4. Configure::read('Company');
6. //yields:
7. array('name' => 'Pizza, Inc.', 'slogan' => 'Pizza for your body and soul');
