將adodb連接到Oracle時發生錯誤

Question

我已經安裝了WAMP服務器。

當試圖連接到Oracle它給這個錯誤：

ORA-12541: TNS:no listener

有誰知道如何解決這個問題？

Answer 1

您的聽衆未啓動（發出命令lsnrctl start）或您的tnsnames.ora錯誤。

Answer 2

在php.ini文件中進行更改 通過刪除來啓用oci驅動程序取消註釋;分號 檢查正確的dll文件 然後

試試這個簡單的類

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); 

只要保持你的error_reporting和display_errors設置在看到錯誤。

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