Introduction | Zend_Json Programmer's Reference Guide | Advanced Usage of Zend_Json

# Basic Usage

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

1. // Retrieve a value:
2. $phpNative = Zend_Json::decode($encodedValue);
4. // Encode it to return to the client:
5. $json = Zend_Json::encode($phpNative);

# 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().

1. // Encode it to return to the client:
2. $json = Zend_Json::encode($phpNative);
3. if($debug) {
4. echo Zend_Json::prettyPrint($json, array ("indent" => " "));
5. }

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.
