做PHP项目的时候需要把input标签设置只读，但是用户可以在浏览器上改，怎么办？
要知道，永远不相信用户提交的数据
前端禁止只是为了用户体验，真正需要过滤用户传输的话只有在后端操作才行。你这种情况下后端做数据操作的时候就不用管这个input的值就好了，只要数据库内的值不改变你随意~
直接div弄个看起来像input的边框
input 不加 name.
后端不处理.
你可以把真正的input hidden掉，然后弄个假的放上面，当然问题依然存在，关键还是后台验证而不是寄托于浏览器端。
后端选择数据的时候可以处理嘛
这个好办，也是设置input属性
<code><input disabled> </code>

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
