使用 Bluemix PHP 应用连接到 Bluemix 上的 DashDB

Question

我无法使用 php 连接到 bluemix 上的 dashdb。我尝试了故障排除，我认为我的错误在函数 $conn = db2_connect( $conn_string, "", "" );

中

我需要在空引号中输入什么值？请帮忙

Answer 1

尝试用单引号替换双引号

$conn = db2_connect($conn_string, ' ', ' ' );

Answer 2

我从 bluemix 支持那里得到了解决方案。 dashdb driver 未正确安装。我在这里得到了 driver：https://github.com/ibmdb/db2heroku-buildpack-php
