Php 尝试将adodb连接到Oracle时出错

我已经安装了WAMP服务器

尝试连接到Oracle时，会出现以下错误：

ORA-12541:TNS:没有侦听器

---

有人知道如何解决这个问题吗？

您的侦听器没有启动（发出命令

lsnrctl start

），或者您的tnsnames.ora是错误的

您的侦听器未启动（发出命令

lsnrctl start

），或者您的tnsnames.ora错误

在php.ini文件中进行更改 通过删除，启用oci驱动程序取消注释；分号 检查是否有正确的dll文件 然后

试试这个简单的类

class AdoConnection {

    public $dbh;

    public function __construct() {
        include_once '../adoconnection/adodb5/adodb.inc.php'; // include your adodb.inc.php file

        $server = "127.0.0.1";
        $user   = "USER/SCHEMA/Database";
        $pwd    = "password";
        $db     = "SID OR Service_Name";

        $this->dbh = NewADOConnection('oci8');
        $this->dbh->Connect(FALSE, $user, $pwd, '(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = ' . $server. ')(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = ' . $db . ') (SID = ' . $db . ')))');
    }

    public function select($sql) {
        $result = $this->dbh->Execute($sql);
        $result = $result->GetRows();
        return $result;
    }

    public function insert($sql) {
        $result = $this->dbh->Execute($sql);
        return $result;
    }
}

$dbh = new AdoConnection();

$dbh->select($sql);
$dbh->insert($sql);

只需保留错误报告并显示错误即可查看错误

ini_set('display_errors',1);
error_reporting(E_ALL);

您的侦听器未启动（

lsnrctl start

）或者您的tnsnames.ora错误。@Klaus-您应该将此作为答案发布您的侦听器未启动（
