Question

我未能使用php连接到bluemix上的dashdb。我尝试了故障排除，我认为我的错误是在函数$ conn = db2_connect（$ conn_string，＆＃34;＆＃34;，＆＃34;＆＃34;）;

我需要在空的引号中加入什么值？请帮忙。

        $details  = json_decode( getenv( "VCAP_SERVICES" ), true );
        $dsn      = $details [ "dashDB" ][0][ "credentials" ][ "dsn" ];
        //$ssl_dsn  = $details [ "dashDB" ][0][ "credentials" ][ "ssldsn" ];

        # Build the connection string

        $driver = "DRIVER={IBM DB2 ODBC DRIVER};";
        $conn_string = $driver . $dsn;     # Non-SSL
        //$conn_string = $driver . $ssl_dsn; # SSL
            echo $conn_string;
        $conn = db2_connect( $conn_string, "", "" );

Answer 1

尝试用单引号替换双引号

$ conn = db2_connect（$ conn_string，＆＃39;＆＃39;，＆＃39;＆＃39;）;

我从bluemix支持获得了解决方案。未正确安装dashdb驱动程序。我在这里找到了司机：https://github.com/ibmdb/db2heroku-buildpack-php

完美无缺：）

使用Bluemix PHP App连接到Bluemix上的DashDB
