Internal Encoder/Decoder

Zend_Json has two different modes depending if ext/json is enabled in your PHP installation or not. If ext/json is installed by default json_encode() and json_decode() functions are used for encoding and decoding JSON. If ext/json is not installed a Zend Framework implementation in PHP code is used for en-/decoding. This is considerably slower than using the PHP extension, but behaves exactly the same.

Still sometimes you might want to use the internal encoder/decoder even if you have ext/json installed. You can achieve this by calling:

::$useBuiltinEncoderDecoder true:
