利用ORA列出全部数据表'email_info'中的数据 下面，我们将逐条读出数据库的内容，并以html表格形式显示'email_info'数据表中的数据   相关PHP代码: PutEnv("ORACLE_SID=ORASID"); $connection = Ora_Logon ("username","password"); if ($connection == false){   echo Ora_ErrorCode($connection).": ".Ora_Error($connection)." ";   exit; } $cursor = Ora_Open ($connection); if ($cursor == false){   echo Ora_ErrorCode($connection).": ".Ora_Error($connection)." ";   exit; }     $query = "select * from email_info"; $result = Ora_Parse ($cursor, $query); if ($result == false){   echo Ora_ErrorCode($cursor).": ".Ora_Error($cursor)." ";   exit;   } $result = Ora_Exec ($cursor); if ($result == false){   echo Ora_ErrorCode($cursor).": ".Ora_Error($cursor)." ";   exit; } echo " "; echo "  Full Name Email Address   "; while (Ora_Fetch_Into ($cursor, &$values)){   $name = $values[0];   $email = $values[1];   echo "  $name $email   "; } echo " "; Ora_Close ($cursor); Ora_Logoff ($connection); ?>   程序运行的浏览效果如下所示:      姓名 Email 地址   春花 springflower@163.com   秋月 autumnmoon@163.com   ... ...
