关于PHP如何获取AJAX值的问题。。。。。。。。。。

Jun 23, 2016 pm 02:28 PM

现在有以下问题
1,在test.php页面有一个
        
        
        
        



然后在这个页面还有一个变量 $arr

现在我想要把option的值赋给$arr,并且是option每次改变的时候,改变$arr的值。
然后我用了AJAX,传回了json值,每次改变option的时候,值分别是10,20,30
我的问题就是,如何把AJAX的值传给$arr。


回复讨论(解决方案)

搜索一下就可以得到很多代码

不用网上搜索,提供个思路就可以了,有点卡住。

$(function() {  $('#top').change(function() {    $.get('test.php', {top:$(this).val()});  });});
Copy after login

$arr = $_GET['top'];
Copy after login

感谢版主的回复,有可能我没有说清楚,我现在在控制器页面得到$arr的值了,然后用json_encode回传到了view页面,现在view页面有一个PHP变量,比方叫$test,请问AJAXS传回来的值如何赋给$test,我用的是YII框架,如果不能赋值,还有什么方法吗?

ajax要修改主界面上的某个值,可以用js把页面上那个值改掉
反正ajax也是js执行的,直接在回调函数中加语句就行
具体做法加个div或span设个id,再写一条js语句
要改的值很多的话干脆把整块页面内容替换掉。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. 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. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
