Oracle实例连接到PHP服务器

问题描述

我在Amazon RDS上建立了一个Oracle数据库,并试图用PHP连接到它.

I have an Oracle database set up on Amazon RDS and am trying to connect to it in PHP.

我相当确定我的连接字符串正确,因为我使用sqlplus连接并且能够检索数据.该服务器是Amazon Linux服务器,但是我也尝试使用其他服务器进行连接并收到错误消息:

I am fairly sure my connection string is correct because I connected using sqlplus and am able to retrieve data. The server is an Amazon Linux server, however I have also tried to connect using a different server and get the error:

我是否需要在服务器或数据库服务器中进行其他设置?我刚刚开始使用AWS,并且不确定是否需要做其他任何事情.

Is there any more set up that I need to do in either the server or the database server, I have just started using AWS and am not sure if anything else needs to be done.

这是我的测试代码:

<html>
    <head>
        <title>PHP Test</title>
    </head>
    <body>
        <?php
            echo "OCI Test<br>";
            $tns = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=xyz.abc.us-west-2.rds.amazonaws.com)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl)));";

            echo "<pre>$tns</pre>\n";

            $username = "xxx";
            $password = "yyy";
            $db = @oci_connect($username, $password, $tns);
            if (!$conn)
            {
                $e = oci_error();
                trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
            }
            $sql = "select * from city";
            $stmt = OCIParse($db, $sql);
            if(OCIExecute($stmt))
            {
                while(OCIFetchInto($stmt, $row, OCI_RETURN_NULLS))
                {
                        echo $row[0]. "-" . $row[1]."<br>";
                }
            }
            OCIFreeStatement($stmt);
        ?>
    </body>
</html>

而且Amazon Linux服务器什么也没显示,而我可以访问的另一台服务器却显示错误,是否为此进行了配置更改?

Also the Amazon Linux server just shows nothing, while another server that I have access to gives errors, is there a configuration change for this?

推荐答案

$tns变量看起来不正确.

尝试

$tns = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=xyz.abc.us-west-2.rds.amazonaws.com)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl)));";
