LR autopay script

[Vytas]

Hello,

I have been trying to make autopay script for Liberty Reserve but I'm always getting "100Invalid XML structure",

My code:

<?php include("settings.php");	
	function Gen_id() {
	return time().rand(0,9999);
}

function Gen_token_hash($securityword) {
	date_default_timezone_set('UTC');
	$token = $securityword.":".gmdate("Ymd:H");
	$token_hash = strtoupper(hash('sha256', $token));
	return $token_hash;
}

function xmlBody($APIname, $securityword, $payeracct, $payeeacct, $amount, $memo, $isprivate) {
	return trim(
	"<TransferRequest id=".Gen_id().">".
	"<Auth>".
	"<ApiName>".$APIname."</ApiName>".
	"<Token>".Gen_token_hash($securityword)."</Token>".
	"</Auth>".
	"<Transfer>".
	"<TransferType>transfer</TransferType>".
	"<Payer>".$payeracct."</Payer>".
	"<Payee>".$payeeacct."</Payee>".
	"<CurrencyId>LRUSD</CurrencyId>".
	"<Amount>".$amount."</Amount>".
	"<Memo>".$memo."</Memo>".
	"<Anonymous>".$isprivate."</Anonymous>".
	"</Transfer></TransferRequest>");
}

	$data = urlencode(xmlBody($APIname,$securityword,$payeracct,$payeeacct,$amount,$memo,$isprivate));
	$URL = "https://api.libertyreserve.com/xml/transfer.aspx?req=".$data;
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $URL);
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
	curl_setopt($ch, CURLOPT_POST, 1);
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	$ex = curl_exec($ch);
	if(!$ex) {
		echo "Error: ".curl_error($ch);
	} else {
		echo $ex;
	}
	curl_close($ch);
?>

There's a some info on how to do this, but i just can't get it to work...
