";   exit;  } $result = OCIExecute ($cursor); if ($result == false){   echo OCIError($cursor)." ";   exit; } echo " "; echo "  Full Name Email Address  "; while (OCIFetchInto ($cursor, $values)){   $name = $values[0];   $email = $values[1];   echo "  $name $email  "; } echo " "; OCILogoff ($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  ... ...
