Methods
readArray() : arrayRead amf array to PHP array
- array = 0x09 integer-data ( [ 1OCTET *amf3-data ] | [OCTET *amf3-data 1] | [ OCTET *amf-data ] )
Returns| Type | Description |
|---|---|
| array |
readDate() : \Zend_DateRead 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| Type | Description |
|---|---|
| \Zend_Date |
readInteger() : int | floatRead 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:
Returns| Type | Description |

| int | float |
readObject() : object | arrayRead an object from the AMF stream and convert it into a PHP object

- Rather than using an array of traitsInfo create Zend_Amf_Value_TraitsInfo
readString() : StringRead 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| Type | Description |
|---|---|
| String |
readTypeMarker(integer $typeMarker = null) : mixedRead 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| Name | Type | Description |
|---|---|---|
| $typeMarker | integer |
| Type | Description |
|---|---|
| mixed | Whatever the corresponding PHP data type is |
| Exception | Description |
|---|---|
| \Zend_Amf_Exception | for unidentified marker type |
readXmlString() : \SimpleXmlConvert XML to SimpleXml If user wants DomDocument they can use dom_import_simplexml
Returns
| Type | Description |
|---|---|
| \SimpleXml | Object |
