我一直在玩 HHVM 配置文件，但我还不能让它向浏览器输出任何致命错误。它显示 E_NOTICE 和 E_WARNING，但是当任何 E_ERROR 发生时，它会使页面留空，并且错误仅出现在 HHVM 日志文件中。

有没有办法让它在浏览器中显示？

我的 HHVM 配置文件如下：

PidFile = /var/run/hhvm/pid

Log {
  Level = Warning
  AlwaysLogUnhandledExceptions = true
  RuntimeErrorReportingLevel = 8191
  UseLogFile = true
  UseSyslog = false
  File = /var/log/hhvm/error.log
  InjectedStackTrace = false
  NativeStackTrace = false
  Access {
    * {
      File = /var/log/hhvm/access.log
      Format = %h %l %u % t \"%r\" %>s %b
    }
  }
}

ErrorHandling {
  CallUserHandlerOnFatals = true
  NoInfiniteLoopDetection = false
  NoInfiniteRecursionDetection = false
  ThrowBadTypeExceptions = false
  ThrowNotices = false
  NoticeFrequency = 1    # 1 out of these many notices to log
  WarningFrequency = 1   # 1 out of these many warnings to log
  AssertActive = false
  AssertWarning = false
}

Debug {
  FullBacktrace = false
  ServerStackTrace = false
  ServerErrorMessage = false
  TranslateSource = false

  RecordInput = false
  ClearInputOnSuccess = true

  ProfilerOutputDir = /tmp

  CoreDumpReport = true
  CoreDumpReportDirectory = /tmp
}

Http {
  DefaultTimeout = 30 # in seconds
  SlowQueryThreshold = 5000 # in ms, log slow HTTP requests as errors
}

Mail {
  SendmailPath = sendmail -t -i
  ForceExtraParameters =
}

Preg {
 BacktraceLimit = 100000
 RecursionLimit = 100000
}

Repo {
  Central {
    Path = /var/log/hhvm/.hhvm.hhbc
  }
}

Eval {
  Jit = true
}

MySQL {
  TypedResults = false
  ReadOnly = false
  ConnectTimeout = 2000      # in ms
  ReadTimeout = 2000         # in ms
  SlowQueryThreshold = 2000  # in ms, log slow queries as errors
  KillOnTimeout = false
}

Nginx：

location ~ \.php$ {
    fastcgi_keep_conn on;

    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;
    fastcgi_read_timeout 900;
    fastcgi_send_timeout 900;
    fastcgi_intercept_errors off;

    fastcgi_pass   127.0.0.1:9000;

    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

您需要在 中启用配置hhvm.server.implicit_flush，php.ini然后您可以发送响应正文以防发生致命错误。为了能够使用错误处理程序捕获致命错误，您还应该启用hhvm.error_handling.call_user_handler_on_fatals.

有关详细信息，请参阅hhvm 上的 github 问题。

使用自定义错误处理程序完全按照您想要的方式处理任何类型的错误。几乎直接取自链接中的示例#1...

function myErrorHandler($errno, $errstr, $errfile, $errline)
{

    switch ($errno) {
    case E_USER_ERROR:
        echo "<b>My ERROR</b> [$errno] $errstr<br />\n";
        echo "  Fatal error on line $errline in file $errfile";
        echo ", PHP " . PHP_VERSION . " (" . PHP_OS . ")<br />\n";
        echo "Aborting...<br />\n";
        exit(1);
        break;

   case E_USER_WARNING:
        echo "<b>My WARNING</b> [$errno] $errstr<br />\n";
        break;

    case E_USER_NOTICE:
        echo "<b>My NOTICE</b> [$errno] $errstr<br />\n";
        break;

    default:
        echo "Unknown error type: [$errno] $errstr<br />\n";
        break;
    }

    /* Don't execute PHP internal error handler */
    return true;
}

set_error_handler("myErrorHandler");

要使这种方法起作用，您必须尽早在代码中设置错误处理程序。

您可能已经注意到我遗漏了一点代码，即检查错误类型是否配置为在您的 php/hhvm 配置中报告的代码。使用上面的代码，无论您的 php/hhvm 配置如何，都会显示错误。（因此您可能希望在生产环境提示中记录而不是回显错误）
