Basic Usage

Usage of Zend_Json involves using the two public static methods available: Zend_Json::encode() and Zend_Json::decode().

// Retrieve a value:
// Encode it to return to the client:

Pretty-printing JSON

Sometimes, it may be hard to explore JSON data generated by Zend_Json::encode(), since it has no spacing or indentation. In order to make it easier, Zend_Json allows you to pretty-print JSON data in the human-readable format with Zend_Json::prettyPrint().

// Encode it to return to the client:
"indent" => " "));
}

Second optional argument of Zend_Json::prettyPrint() is an option array. Option indent allows to set indentation string - by default it's a single tab character.
