【中文标题】Facebook Xmpp 聊天 API 错误【英文标题】：Facebook Xmpp Chat API Error 【发布时间】：2013-09-09 09:36:10 【问题描述】：

我正在使用以下代码向我的朋友发送聊天消息。但是这段代码不起作用。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得到了这个代码。它没有显示任何错误，但我无法发送消息。

有人有它的工作代码示例吗？

我也面临这个......让我们等一下 【参考方案1】：

    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);

这可以帮助你。
