/includes/init.php文件代码片段以下：
。。。。
/* 初始化数据库类 */
require(ROOT_PATH . 'includes/cls_mysql.php');
require(ROOT_PATH . 'includes/lib_soap.php');
$db = new cls_mysql($db_host, $db_user, $db_pass, $db_name);
$db->set_disable_cache_tables(array($ecs->table('sessions'), $ecs->table('sessions_data'), $ecs->table('cart')));
$db_host = $db_user = $db_pass = $db_name = NULL;
。。。。。。。。。。我的test.php的文件如下，我怎么引用$db变量呢？define('IN_ECS', true);
require ('../includes/init.php');
function pay(){
$timeStamp = date('Y-m-d H:i:s');
$field_values = array("pay_status" => 2,"order_status"=>1,"pay_time"=>$timeStamp);
$orderId=2017072730194;
$re = $db->autoExecute('ecs_order_info', $field_values, "UPDATE", "order_sn = $orderId"); //这样引用是错误的
echo $re;
}可以看到，$re = $db->autoExecute('ecs_order_info', $field_values, "UPDATE", "order_sn = $orderId"); 这样是错误的，应该怎么引用呢？ 最佳答案
