Answer 1

You can use SabreAMF to encode/decode AMF data on PHP.

Answer 2

@Ivan Dyachenko Thanks for pointing towards SabreAMF Below is the way I successfully decoded and mapped the AMF3 encoded object received from Flex/Flash on sockets

include_once 'SabreAMF/AMF3/Serializer.php';
include_once 'SabreAMF/AMF3/Deserializer.php';
include_once 'SabreAMF/OutputStream.php';
include_once 'SabreAMF/InputStream.php';
include_once 'SabreAMF/TypedObject.php';
include_once 'SabreAMF/ClassMapper.php';

/************DECODER*****************/
SabreAMF_ClassMapper::registerClass('FLASH_CLASS_NAME','PHP_CLASS_NAME'); //CLASSES SHOULD BE SAME
$inputStream = new SabreAMF_InputStream($buffer);
$des = new SabreAMF_AMF3_Deserializer($inputStream);
$obj = $des->readAMFData();
//$obj will contain the instance of PHP_CLASS_NAME with the properties set as the values sent by Flex/Flash
/************END DECODER*****************/

/**************ENCODER******************/
$classObj = new PHP_CLASS(); //PHP_CLASS is your class
$object = new SabreAMF_TypedObject('FLASH_CLASS_NAME',$classObj); //FLASH_CLASS_NAME IS NAME OF CLASS AVAILABLE TO FLASH FOR MAPPING
$outputStream = new SabreAMF_OutputStream();
$serializer = new SabreAMF_AMF3_Serializer($outputStream);
$serializer->writeAMFData($object);
$output = $outputStream->getRawData();

//$output is AMF Encoded string to be sent to FLEX/FLASH. 
/***********END ENCODER***************/

Please take a look at this - https://github.com/neoxic/php-amf3 - this is a very reliable PHP extension for encoding/decoding AMF3 streams.
