我试图在我的网站上获得新的facebook php sdk设置。我正在运行最新的稳定版本的php。我以前从来没有摆弄过名称空间。有人能告诉我我哪里做错了吗?
我得到这个错误
Fatal error: Class 'FacebookSession' not found in
当我运行这段代码
FacebookSession::setDefaultApplication( 'xxx','yyy' );
…

你不需要使用完整的路径到Facebook SDK，除非你试图从一个完全不同的位置访问它。您应该能够使用一个相对路径访问它，比如lib/fb/Facebook/GraphSessionInfo.php，假设您的index.php文件位于site文件夹。
同样，尝试执行以下操作，看看是否仍然得到错误:
Facebook'FacebookSession::setDefaultApplication( 'xxx','yyy' );
问题是由于PEAR安装在服务器上的电子邮件。php设置中的include路径被修改。
我实际上删除了PEAR，将PHP设置回默认包含路径，并将电子邮件切换为swiftmailer。
