* Converts to and from JSON format.
6
* JSON (JavaScript Object Notation) is a lightweight data-interchange
7
* format. It is easy for humans to read and write. It is easy for machines
8
* to parse and generate. It is based on a subset of the JavaScript
9
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
10
* This feature can also be found in Python. JSON is a text format that is
11
* completely language independent but uses conventions that are familiar
12
* to programmers of the C-family of languages, including C, C++, C#, Java,
13
* JavaScript, Perl, TCL, and many others. These properties make JSON an
14
* ideal data-interchange language.
16
* This package provides a simple encoder and decoder for JSON notation. It
17
* is intended for use with client-side Javascript applications that make
18
* use of HTTPRequest to perform server communication functions - data can
19
* be encoded into JSON notation for use in a client-side javascript, or
20
* decoded from incoming Javascript requests. JSON format is native to
21
* Javascript, and can be directly eval()'ed with no further parsing
24
* All strings should be in ASCII or UTF-8 format!

* Brief example of use:
99
* // create a new instance of Services_JSON
100
* $json = new Services_JSON();
102
* // convert a complexe value to JSON notation, and send it to the browser
103
* $value = array('foo', 'bar', array(1, 2, 'baz'), array(3, array(4)));
104
* $output = $json->encode($value);
107
* // prints: ["foo","bar",[1,2,"baz"],[3,[4]]]
109
* // accept incoming POST data, assumed to be in JSON notation
110
* $input = file_get_contents('php://input', 1000000);
111
* $value = $json->decode($input);
117
* constructs a new JSON instance
119
* @param int $use object behavior flags; combine with boolean-OR
122
* - SERVICES_JSON_LOOSE_TYPE: loose typing.
123
* "{...}" syntax creates associative arrays
124
* instead of objects in decode().
125
* - SERVICES_JSON_SUPPRESS_ERRORS: error suppression.
126
* Values which can't be encoded (e.g. resources)
127
* appear as NULL instead of throwing errors.
128
* By default, a deeply-nested resource will
129
* bubble up with an error, so all return values
130
* from encode() should be checked with isError()
