我的数据库中存储了一个布尔（位）值。问题是当我在本地服务器上运行PHP脚本时，我得到0或1的值，具体取决于使用mySQL查询针对id存储在Database中的值。但是，在活动服务器上的相同脚本绝对不返回0和1.我的变量保持为空。任何可能的解释。 $ status的值在实时服务器上保持为空，但适用于本地
<?php
session_start();
require_once __DIR__ . '/connect.php';
if (!$_SESSION['loginadmin'])
{
header("location:error.php");
}
else

答案 0 :(得分：1)
我的本地服务器上的状态值为BIT，但在本地服务器上工作正常，但它在实时服务器上返回空。 FIX ON LIVE SERVER：在实时服务器上将状态列类型从BIT更改为TINYINT。
