Sending Negative Integers through AMFPHPThere is a weird bug in AMFPHP regarding sending negative integers. If you try and send a number such as -87, it shows up as 4294967209 in php. I did some digging and found on the amfphp forums that it has to do with amfphp's readAmf3Int() method in AMFDeserialzer.php. Here is the updated function that was posted on the forum:
PHP:
-
function readAmf3Int()
-
{
-
$res = 0;
-
$int = $this->readByte();
-
-
if($int <128) {
-
return $int;
-
} else {
-
$int = ($int & 0x7f) <<7;
-
-
$tmp = $this->readByte();
-
-
if($tmp <128) {
-
$int |= $tmp;
-
}else{
-
$int = ($int | ($tmp & 0x7f)) <<7;
-
$tmp = $this->readByte();
-
if($tmp <128){
-
$int |= $tmp;
-
}else{
-
$int = ($int | ($tmp & 0x7f)) <<8;
-
$tmp = $this->readByte();
-
$int |= $tmp;
-
}
-
}
-
}
-
-
$mask = 1<<28;
-
$res = -($int & $mask) | $int;
-
-
return $res;
-
}
