我已经看到这个非常有用的帖子问题，并尝试按照它概述的步骤进行操作。但是我对此很陌生，所以我想我可能在某个地方搞砸了。
我试图定制网页上的代码，该代码是为了让某人登录到我的情况而创建的。
我正在制作一个日历，这就是我需要这个数据库的原因。主要目标：在 Bluemix 中制作类似日历的 Web 应用程序并将数据库服务绑定到它，以便我可以存储事件。
这些是我采取的步骤：
- 使用 PHP、HTML 和 CSS 创建了一个网站
- 绑定服务 (dashDB) 并通过上传包含两列的 .csv 文件放入表中，一列标记为用户名，另一列标记为密码。有两条记录，(Jessica - Fish, Tom - Bear) 它被称为 USERNAMEFILE
- 包括一个 php 文件，该文件将连接到名为 ConexionDB.php 的数据库
- '需要'我尝试访问数据库的名为 index.php 的 php 文件中的 ConexionDB.php 文件。在尝试访问数据库时，我只是想看看是否可以。它目前除了打印数字 1 之外没有其他用途。
但是，当我完成所有这些操作，然后使用此命令“cf push HybridCloudEventsTest -b GitHub ”将我的项目推出，然后转到我的网站时，我发现该页面无法正常工作，错误代码 500。我也可以将发生的事情放在我的 cmd行，如果有帮助的话。我还在下面给出了我的代码以及每个文件的标题。我没有包括我所有的 index.php 文件，因为它在我输入数据库代码之前就已经工作了，所以我相信这就是问题所在.如果您需要我的索引和css代码，我也可以发布它。感谢任何帮助
ConexionDB.php
<?php
if( getenv("VCAP_SERVICES") ) {
$json = getenv("VCAP_SERVICES");
}

else {

}

$services_json = json_decode($json,true);
$bludb_config = $services_json["dashDB"][0]["credentials"];
// Create DB connect string

$stmt = db2_prepare($conn, $sql);
$result = db2_execute($stmt);
echo $result;

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
