最后，我能够用以下两行重现该问题：

session_set_save_handler(new SessionHandler());
session_start();

当我这样做时，我得到一个 WSOD！知道为什么会这样吗？

==================================================== ==========

最后，我越来越深入地挖掘并将其缩小到由于失败而引起的问题session_start()；不过，我不知道为什么它会以这种方式失败。

所以，问题归结为：当session_start()被调用时NativeSessionStorage::start()，它失败了。但是，当我创建一个示例测试页面时，session_start()它成功了！

Silex 有什么不同吗？！

我保留下面的文字，以便任何面临类似问题的人都能理解失败背后的原因。

==================================================== ==========

我最近尝试从 Php 5.3 切换到 Php 5.4，而我基于 Silex 的网站停止使用 WSOD。

我检查了 PHP 错误日志，我看到： Premature end of script headers: php54.cgi

我尝试了很多东西，最后想到了在网上问:(。这是我尝试过的：

  1. 创建了一个简单的 Silex 项目并检查它是否正常工作。不，不是。

  2. 在 Silex 初始化之前添加代码并在app[debug] = true之后设置：

    ini_set('display_errors', 1);
error_reporting(-1);
ErrorHandler::register();
if ('cli' !== php_sapi_name()) {
    ExceptionHandler::register();
}

  3. 试图检查代码的范围。但我一直在继续介入。我一直坚持到NativeSessionStorage::start()放弃，所以它一直工作到那时，我在那里产生的任何错误都会按预期正确报告。

  4. 尝试查看其他条目以了解如何修复 BSOD，但没有一个条目真正解释了从 PHP 5.3 迁移到 PHP 5.4 会发生什么变化！这就是我所做的一切。只是相应地更改了 PHP 版本和 PHP.INI。下面是我现在使用的 PHP.INI。

我想我以前也遇到过同样的问题。如果您使用的是 PHP 版本 < 5.4.11 - SessionHandler 实现中存在错误 - 请检查此链接，也许它与某种相关...

也许运行 'strace' 来查看 PHP 失败的地方。也许你有基于用户试图访问某些资源的权限问题。例如应该保存会话的目录。
