Home Backend Development PHP Tutorial 提交表单,$_post[XX]获得的数据为乱码

提交表单,$_post[XX]获得的数据为乱码

Jun 23, 2016 pm 02:09 PM

出现问题后,我按网上的说法
在index.php(提交表单的页面)前面加了
在page-1.php(要获取的页面)
加了  header("Content-Type:text/html;charset=GB2312");
  $key=$_POST['key']=iconv("UTF-8","gb2312",$_POST["key"]);  
结果还是不行。我是菜鸟咯,随便发表意见,反正把问题解决就行!

你的数据是页面输入的还是文件输入的?

你的数据是页面输入的还是文件输入的?
提交表单呀,从而来输入的呀!

index.php 首行加上
header("Content-Type:text/html;charset=GB2312");

另外,把php文件也设置为gbk编码

index.php 首行加上
header("Content-Type:text/html;charset=GB2312");

弱弱问下,header("Content-Type:text/html;charset=GB2312");
 和这个"

header() 函数向客户端发送原始的 HTTP 报头。
 元素可提供有关页面的元信息

关于meta的介绍,我一下说不清楚,看下面的介绍吧
http://www.w3school.com.cn/tags/tag_meta.asp

在index.php(提交表单的页面)前面加了
如果这个 meta 生效的话,提交的表单就是 GB2312 编码的了
所以  在page-1.php(要获取的页面)
  $key=$_POST['key']=iconv("UTF-8","gb2312",$_POST["key"]);
是错误的!
你这是把 GB2312 当做 UTF-8 处理,怎么能得到正确的结果呢?  

header("Content-Type:text/html;charset=GB2312");
位于 http 协议头中,其优先级高于

既然index.php编码的方式为gb2312,就将page-1.php的编码前加上header("Content-Type:text/html;charset=GB2312");
可我这么一改,还是一样,对于这方面感觉太吃力了。

结果还是不行、还是一样....

什么叫“还是不行”、“还是一样”
到底是怎样的“不行”、怎样的“一样”

就是说$_post获得的变量数据仍旧是乱码(我单独输出了的)
版主,别介意呀,你可以随便说我的,但自己别生气咯,身体是自己的。本来计算机的,都是在花费着生命力。

麻烦大家了,昨天终于把这个问题解决了,编码方式我全部改成了"UTF-8",(因为mysql建表时,就是UTF-8).麻烦各位。我以后也定会注意每个页面的编码方式。

解决就好,知其然也要知其所以然,自己总结一下吧

其实每次传输过程都要考虑前后的编码问题,别忘了,编辑器打开php文件写代码也是一次传输过程,保存是另一次,按这样的思路,自己列出每一个传输过程再检查问题就变简单了,

统一编码就好,

用个好的编辑器也很重要,

推荐notepad++,想改编码,非常方便。

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
