|
|

* so objects | arrays to be encoded with Zend_Json can contain native
|
|
* Javascript Expressions.
|
|
*
|
|
* Example:
|
|
* <code>
|
|
* $foo = array(
|
|
* 'integer' =>9,
|
|
* 'string' =>'test string',
|
|
* 'function' => Zend_Json_Expr(
|
|
* 'function(){ window.alert("javascript function encoded by Zend_Json") }'
|
|
* ),
|
|
* );
|
|
*
|
|
* Zend_Json::encode($foo, false, array('enableJsonExprFinder' => true));
|
|
* // it will returns json encoded string:
|
|
* // {"integer":9,"string":"test string","function":function(){window.alert("javascript function encoded by Zend_Json")}}
|
|
