我目前收到此错误
解析错误：语法错误，意外的 T_OBJECT_OPERATOR
请注意：
- 我是 php 新手。
- 我所做的基本上就是合并 http://phpir.com/part-of-speech-tagging和 http://tapetyclick.com/blog/2013/06/25/twitter-xml-feeds-are-back
- 任何帮助将不胜感激。
- 我的总体目标是能够收集所有 twitter 搜索结果并按其世界级（词性）对每个单词进行分类
无论如何，这是我的代码：

上面的代码返回以下错误
解析错误：语法错误，/var/www/test/Twitter/index.php 中的意外 T_OBJECT_OPERATOR
对于这条线
$tags = new PosTagger('lexicon.txt')->tag($status->text);
