我正在使用以下代码将聊天消息发送给我的朋友。 但是此代码不起作用。 如果我做错了什么，请纠正我。 我一直在互联网上搜索这项工作，并获得了此代码。 它没有显示任何错误，但是我无法发送消息。

function recv_xml($fp, $size=4096) {
$xml = fread($fp, $size);
if (!preg_match('/^</', $xml)) {
$xml = '<' . $xml;
}
if ($xml === "") {
return null;
}
// parses xml
$xml_parser = xml_parser_create();
xml_parse_into_struct($xml_parser, $xml, $val, $index);
xml_parser_free($xml_parser);
return array($val, $index);
}
