AMFPHP how to access classes outside amfphp

Question

My class log is in directory:

www/includes/classes/log.php

with a method

public function add($type){
    if($type!=''){
        $this->addRow($type);
    }
}

AmfPHP class abc exist in directory

www/game/r1/amfphp-file/serv/xyz.php

it has a function which calls above method like this

$log = new log();
$log->add('gameStart');

The problem comes in my flash game AS3: NetConnection.Call.BadVersion

when I remove these lines game runs fine (without any trouble):

//$log = new log();
//$log->add('gameStart');

what I have figured out that my external class is not accessible or ...

Answer 1

"bad version" means that you probably have some PHP error message that is being output. This corrupts your return data.

See www.silexlabs.org/amfphp/documentation/troubleshooting-and-debugging-your-project/ especially What is “NetConnection.Call.BadVersion”?
