Fatal error: Uncaught TypeError: Unsupported operand types: null & array

[cy-polo]

Hello,

I'm trying to configure a small AMF server in PHP, but I get an error that seems to come from SabreAMF that I don't understand, when creating the AMF server (new SabreAMF_Server()).
Can you please help me?

Here is what I do:

<?php

include "vendor/autoload.php";

$server = new SabreAMF_Server(); // Unsupported operand types: null & array 

Here is my error:

Fatal error: Uncaught TypeError: Unsupported operand types: null & array in D:\xampp\htdocs\vendor\sabre\amf\lib\SabreAMF\AMF0\Deserializer.php:129 Stack trace: #0 D:\xampp\htdocs\vendor\sabre\amf\lib\SabreAMF\AMF0\Deserializer.php(67): SabreAMF_AMF0_Deserializer->readArray() #1 D:\xampp\htdocs\vendor\sabre\amf\lib\SabreAMF\Message.php(146): SabreAMF_AMF0_Deserializer->readAMFData(10, true) #2 D:\xampp\htdocs\vendor\sabre\amf\lib\SabreAMF\Server.php(79): SabreAMF_Message->deserialize(Object(SabreAMF_InputStream)) #3 D:\xampp\htdocs\Gateway.php(23): SabreAMF_Server->__construct() #4 {main} thrown in D:\xampp\htdocs\vendor\sabre\amf\lib\SabreAMF\AMF0\Deserializer.php on line 129

Here is what the client sends:

Thank you in advance for your response, and I'm sorry to bother you if this is an old unmaintained project.

Hi! It's been more than a decade since I worked on this. I no longer have the context to help. Whoever is interested in using this is probably on their own, but ill accept pull requests (mostly blindly)

Hello,

thank you for your answer, even if I'm annoyed that I can't solve this problem.
I understand that diving back into a project that can be used is no longer interesting.

Have a nice day!

hey , could you find solution to read amf data of family farm ?

[evert]

@bastetcheat this library has nothing to do with farming.

@evert
family farm is a Flash game....

ok, well that's still off-topic for this issue. Try to find a different venue for this question

In case anyone else is looking at this issue, there are two solutions: use an older version of PHP (pre 8), or in AMFDeserializer.php on line 241 try changing the line that reads:

$this->storedObjects[] & = $data;

to

$this->storedObjects[] = &$data;
