我使用 Windows 和 XAMPP 编写了一个 PHP 应用程序。我一直尝试在装有 Lighttpd 1.4.26 的 Ubuntu 10.10 上运行它。该应用程序的部分功能运行正常，但每当我尝试登录时，都会出现 500 - 内部服务器错误页面。
/var/log/lighttpd/error.log 中唯一显示的内容是
2011-02-25 13:43:13: (mod_fastcgi.c.2582) unexpected end-of-file (perhaps the fastcgi process died): pid: 1169 socket: unix:/tmp/php.socket-0
2011-02-25 13:43:13: (mod_fastcgi.c.3367) response not received, request sent: 1596 on socket: unix:/tmp/php.socket-0 for /~denton/customer-facing-portal/index.php?, closing connection
如果我有任何来自 PHP 的输出，那么调试起来就会容易得多。关于如何获取这些输出，您有什么想法吗？

一极其我在这个问题中无意中忽略的一个重要细节是我正在使用 dblib 来访问 Microsoft SQLServer。
我没有提到它，因为它似乎并不重要；我拼凑了一些测试脚本，数据库访问似乎运行良好。不幸的是，Dblib 有一个错误，每当您输入SELECT具有 type 值的列时，它就会崩溃money。此崩溃会导致 fastcgi 子进程也崩溃。
是的。在 PHP 脚本的登录部分之后，我的程序立即选择了很多东西来组合用户资料……包括金钱价值。哎呀！
