为长篇阅读道歉，但我认为在前期包含尽可能多的细节是有意义的，而不是等待人们询问各种配置、日志等。
我有一台运行 XP 并安装了 One Core API 的旧 PC。
我正在使用它来测试具有多个 PHP 版本的 Apache 2.4.38。一切正常，除了 PHP 7.2 和 7.3 为所有 php 文件返回 404 状态并显示“未指定输入文件”消息。Apache 日志，如果我正确阅读它们，表明 php-cgi.exe 被正确调用，并且即使文件存在也负责返回此状态。
SysInternals Process Monitor 显示 Apache 的“httpd.exe”发现 php 文件没有问题。在此之后，直到 7.1 的所有 PHP 版本都检查“user.ini”和请求的 php 文件。然而，版本 7.2 和 7.3 只检查“user.ini”，根本不尝试访问请求的 php 文件。尽管如此，它们还是返回 404 错误，并显示消息“未指定输入文件”。
我现在已经将所有东西缩小到一个简单的工作配置，如果有人想自己尝试一下，下面都会显示。Apache 和所有 PHP 版本都安装在一个根据其 5 位版本 ID 命名的文件夹中。有一个测试站点“test2.local”，其中包含一个索引文件。
- 一切都是 32 位的，所有 PHP 版本都是非线程安全 (nts) 版本。
- Apache 是 Apache Lounge 的当前版本（截至 2019 年 2 月 8 日）。
- PHP <=5.5 是每个版本的最后构建。
- PHP >=5.6 是所有当前版本（截至 2019 年 2 月 8 日）。
- PHP 构建都是来自 php.net 的预构建二进制文件。
- 所有 VC 运行时都已安装并正常工作（2008、2012、2017）。
- 为了简单起见，没有加载任何 PHP 扩展。
- 所有 PHP 版本在它们自己的文件夹中都有自己的“php.ini”文件。
- 所有二进制文件都经过检查，除了通常的罪魁祸首（依赖于未安装的第三方软件的 PHP 扩展）外，没有缺少依赖项。
- “php.exe”和“php-cgi.exe”的所有版本都可以在命令行中完美运行，并且不会在 PHP 错误日志中记录任何错误。
- 最高 7.1 的所有“php-cgi.exe”版本都可以与 Apache 完美配合，也不会记录任何错误。
- “php-cgi.exe”的 7.2 和 7.3 版本在 Apache 错误日志中显示所有 php 文件的 404 状态，但同样，不要在 PHP 错误日志中记录任何内容。

除了 7.1 及更高版本包含“default_charset”指令外，所有 PHP 配置都相同，如果不存在，则会导致 500 内部服务器错误。由于 php.net 的迁移页面，我找到了适用于 7.1 的解决方案（最初也不起作用，但现在可以）。我找不到任何表明 7.2 或 7.3 需要进一步更改的内容。

（我在很多地方读到修复路径信息设置应该是“FcgidFixPathinfo = 1”和“cgi.fix_pathinfo = 1”，但我尝试过没有成功。实际上，打开这些设置只有效果在所有工作的 PHP 版本中，“SCRIPT_NAME”和“PHP_SELF”变量都设置为“D:/index.php”而不是“/index.php”。换句话说，打开它会破坏东西而不是修复任何东西。 )
随着一切的启动和运行，测试就像在“ http://test2.local/index.php ”请求页面一样简单。PHP <=7.1 的结果都是一样的，所以我将使用 7.1 的日志。同样，7.2 和 7.3 的结果是相同的，所以我将使用 7.2 的日志。没有 PHP 版本记录任何错误或崩溃。每个版本都在第一次请求时成功加载并继续愉快地运行，直到重新启动 Apache。
