我看到了这篇非常有用的文章，并尝试按照它概述的步骤进行操作。然而，我是新手，所以我想我可能在某个地方搞砸了

我尝试在网页上定制代码，该网页是为了让某人登录到我的情况而创建的

我正在制作日历，所以我需要这个数据库。主要目标：在Bluemix中创建类似日历的web应用程序，并将数据库服务绑定到该应用程序，以便存储事件

以下是我采取的步骤：

  • 使用PHP、HTML和CSS创建网站
  • 绑定服务（dashDB）并通过上载一个.csv文件放入表中，该文件有两列，一列标记为用户名，另一列标记为密码。有两个记录，（杰西卡-鱼，汤姆-熊）它被称为用户名文件
  • 包括一个php文件，该文件将连接到名为ConexionDB.php的数据库
  • “required”是php文件index.php中的ConexionDB.php文件，我尝试在其中访问数据库。当我试图访问数据库时，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 然而，当我做了所有这些，然后用这个命令推出我的项目时“cf推送HybridCloudEventsTest-b，然后转到我的网站，我发现页面无法正常工作，错误代码为500。如果有帮助的话，我也可以把发生的事情写在我的命令行中。我还在下面展示了我的代码，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工作了，所以我相信这就是问题所在。如果你需要我的索引和css代码，我也可以发布。谢谢你的帮助

    ConexionDB.php

    <?php
if( getenv("VCAP_SERVICES") ) {
$json = getenv("VCAP_SERVICES");
}
// No DB credentials
else {
    throw new Exception("No Database Information Available.", 1);
}

// Decode JSON and gather DB Info
$services_json = json_decode($json,true);
$bludb_config = $services_json["dashDB"][0]["credentials"];

// Create DB connect string
$conn_string = "DRIVER={IBM DB2 ODBC DRIVER};DATABASE=".
$bludb_config["db"].
";HOSTNAME=".
$bludb_config["host"].
 ";PORT=".
$bludb_config["port"].
";PROTOCOL=TCPIP;UID=".
$bludb_config["username"].
";PWD=".
$bludb_config["password"].
";";

    您需要确保CF应用程序包含用于PHP的dashDB/DB2驱动程序。将此附加到cf push命令可以修复它，
    -b

    您需要安装db2包驱动程序

    如果已安装Cloud Foundry，请运行此命令：cf push-b

    或

    将buildpack选项添加到manifest.yml文件[manifest.yml]
    Buildpack:

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.
