string $_source =

Use to maintain a "pointer" to the source being decoded

int $_sourceLength =

Caches the source length

Methods

__construct(string $source, int $decodeType) : void

Constructor

Parameters

Name	Type	Description
$source	string	String source to decode
$decodeType	int	How objects should be decoded -- see {@link Zend_Json::TYPE_ARRAY} and {@link Zend_Json::TYPE_OBJECT} for valid values

_decodeArray() : array

Decodes a JSON array format: [element, element2,.

..,elementN]

Returns

Type	Description
array

_decodeObject() : array | \StdClass

Decodes an object of the form: { "attribute: value, "attribute2" : value,.

..}

If Zend_Json_Encoder was used to encode the original object then a special attribute called __className which specifies a class name that should wrap the data contained within the encoded source.

Decodes to either an array or StdClass object, based on the value of $_decodeType. If invalid $_decodeType present, returns as an array.

Returns

Type	Description
array \| \StdClass

_decodeValue() : mixed

Recursive driving rountine for supported toplevel tops

Returns

Type	Description
mixed

_eatWhitespace() : void

Removes whitepsace characters from the source input

_getNextToken() : int

Retrieves the next token from the source stream

Returns

Type	Description
int	Token constant value specified in class definition

_utf162utf8(string $utf16) : string

static

Convert a string from one UTF-16 char to one UTF-8 char.

Normally should be handled by mb_convert_encoding, but provides a slower PHP-only method for installations that lack the multibye string extension.

This method is from the Solar Framework by Paul M. Jones

Parameters

Name	Type	Description
$utf16	string	UTF-16 character

Returns

Type	Description
string	UTF-8 character

decode(string $source = null, int $objectDecodeType = \Zend_Json::TYPE_ARRAY) : mixed

static

Decode a JSON source string

Decodes a JSON encoded string. The value returned will be one of the following: - integer - float - boolean - null - StdClass - array - array of one or more of the above types

By default, decoded objects will be returned as associative arrays; to return a StdClass object instead, pass Zend_Json::TYPE_OBJECT to the $objectDecodeType parameter.

Throws a Zend_Json_Exception if the source string is null.

Parameters

Name	Type	Description
$source	string	String to be decoded
$objectDecodeType	int	How objects should be decoded; should be either or {@link Zend_Json::TYPE_ARRAY} or {@link Zend_Json::TYPE_OBJECT}; defaults to TYPE_ARRAY

Returns

Type	Description
mixed

Throws

Exception	Description
\Zend_Json_Exception
