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().
<?php
// Encode it to return to the client:
$json = Zend_Json::encode($phpNative);
if($debug) {
echo Zend_Json::prettyPrint($json, array("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.
