二招解决php乱码问题_PHP
php网页出现乱码一般是在建立数据库时用的编码和php网页的编码不同造成的,
用phpmyadmin建立的数据库如果你不指定编码他默认是latin1_swedish_ci 编码,既瑞典语不区分大小写,而我们中国做的网页不是GBK就是GB2312编码,这样不出现乱码才怪.
1,建立数据库时指定编码.
在此再唠叨一下常用的编码,免的新手又迷茫:
如果你做的是简体中文网页,那么你在建立数据库时用GB2312编码,gb2312_chinese_ci.
如果你做的是繁体中文网页,那么你建立数据库时要用gib5编码, big5_chinese_ci
如果你做的网页有简体也有繁体中文,那么推荐你用GBK编码,gbk_chinese_ci . GBK包含的字码比GB2312要多,当然繁体也在其中.
如果你做的是多国语言网页,那么推荐你用UTF-8编码 . mysql中有二种utf8编码可供选择 : utf8_unicode_ci与utf8_general_ci 笔者一般用utf8_general_ci ,关于这二种编码的区别,请参考本站的另一篇文章: Mysql中校对集utf8_unicode_ci与utf8_general_ci的区别
我们用UTF-8编码为例建立数据库如图:
语法: mysql_query("SET NAMES 'utf8'");
例如:
复制代码 代码如下:
$conn=mysql_connect('127.0.0.1','root','123456');
mysql_query("set names 'utf8'",$conn); //解决乱码
mysql_select_db('test1',$conn);
一般情况下只要你做好了这二步,你的程序是不会出现乱码的
二般情况:
二般情况一般出现的不多,多出现在做的程序语言比较多,比如有时做utf8的,有时做gb2312的,有时又要做big5的网页,用IDE建立的.php文件编码和程序要显示的编码不同而引起的.
比如,我上次做了个gb2312的简体中文网页,现在老板又有吩咐要做个gbi5网页,但我的ide用的却是gb2312的编码
就拿我常用的IDE Dreamweaver来说吧
如果还搞不定,那么在网页头部加一行http头信息
header("Content-Type:text/html;charset=utf-8");
注意:在发送header头信息时header前面不可以有任何输出,包括空格在内.
好了写了这么多,快看看你的程序属于哪个情况引起的乱码吧.

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.
