\Zend_Amf_Parse_Amf3_Deserializer

Package: Zend\Amf\Parse\Amf3
Read an AMF3 input stream and convert it into PHP data types.

Logic for deserialization of the AMF envelop is based on resources supplied by Adobe Blaze DS. For and example of deserialization please review the BlazeDS source tree.

Constructor

Inherited from: \Zend_Amf_Parse_Deserializer::__construct()
Parameters
NameTypeDescription
$stream\Zend_Amf_Parse_InputStream
methodpublicreadArray() : array

Read amf array to PHP array

  • array = 0x09 integer-data ( [ 1OCTET *amf3-data ] | [OCTET *amf3-data 1] | [ OCTET *amf-data ] )
Returns
TypeDescription
array
methodpublicreadDate() : \Zend_Date

Read and deserialize a date

Data is the number of milliseconds elapsed since the epoch of midnight, 1st Jan 1970 in the UTC time zone. Local time zone information is not sent to flash.

  • date = 0x08 integer-data [ number-data ]
Returns
TypeDescription
\Zend_Date
methodpublicreadInteger() : int | float

Read and deserialize an integer

AMF 3 represents smaller integers with fewer bytes using the most significant bit of each byte. The worst case uses 32-bits to represent a 29-bit number, which is what we would have done with no compression. - 0x00000000 - 0x0000007F : 0xxxxxxx - 0x00000080 - 0x00003FFF : 1xxxxxxx 0xxxxxxx - 0x00004000 - 0x001FFFFF : 1xxxxxxx 1xxxxxxx 0xxxxxxx - 0x00200000 - 0x3FFFFFFF : 1xxxxxxx 1xxxxxxx 1xxxxxxx xxxxxxxx - 0x40000000 - 0xFFFFFFFF : throw range exception

0x04 -> integer type code, followed by up to 4 bytes of data.

Parsing integers on OSFlash for the AMF3 integer data format:

methodpublicreadObject() : object | array

Read an object from the AMF stream and convert it into a PHP object

Returns
TypeDescription
object | array

Rather than using an array of traitsInfo create Zend_Amf_Value_TraitsInfo  
methodpublicreadString() : String

Read and deserialize a string

Strings can be sent as a reference to a previously occurring String by using an index to the implicit string reference table. Strings are encoding using UTF-8 - however the header may either describe a string literal or a string reference.

  • string = 0x06 string-data
  • string-data = integer-data [ modified-utf-8 ]
  • modified-utf-8 = *OCTET
Returns
TypeDescription
String
methodpublicreadTypeMarker(integer $typeMarker = null) : mixed

Read AMF markers and dispatch for deserialization

Checks for AMF marker types and calls the appropriate methods for deserializing those marker types. markers are the data type of the following value.

Parameters
NameTypeDescription
$typeMarkerinteger
Returns
TypeDescription
mixedWhatever the corresponding PHP data type is
Throws
ExceptionDescription
\Zend_Amf_Exceptionfor unidentified marker type
methodpublicreadXmlString() : \SimpleXml

Convert XML to SimpleXml If user wants DomDocument they can use dom_import_simplexml

Returns
TypeDescription
\SimpleXmlObject
