php 数据库中添加温度摄氏度(℃)字段是什么类型 在页面显示=需要什么设置
php 在数据库表中添加一个温度摄氏度的字段是什么字段类型 在页面上显示℃时候(比如-1℃~8℃)需要什么设置吗
------解决方案--------------------
字符难道不行么?
------解决方案--------------------
你用int存储即可
显示的时候再把℃加上来
------解决方案--------------------
字段内容中包含“℃”的话用 varchar 类型
否则 int 和 varchar 都可以
℃ 只不过是个字符而已
$a = -1;
$b = 8;
echo "{$a}℃ ~ {$b}℃";
