字符串转码问题
utf-8 gbk
$str="黑色";这个字符串我用mb_detect_encoding函数检查是 UTF-8编码,
$s1 = iconv ( 'utf-8', 'gbk', $string );
$s1 = mb_convert_encoding ( $string, "GBK", "UTF-8" );
我用上面两种方法进行转码,结果都会乱码,请教是什么原因?
回复讨论(解决方案)
字符太少的情况下detect会不准确的
至于乱码还会受输出的编码影响,例如页面指定编码是gbk,但php输出的是utf-8字串,因素很多
$str="黑色";
如果用mb_detect_encoding函数检查是 UTF-8编码
那么就表示你的程序文件是 utf-8 编码的
既然程序是 utf-8 编码的,当然输出也就是 utf-8 的了
你把 utf-8 的转成 gbk 的,出现乱码就是必然的了
乱码很正常啊,你的页面是utf8的,但是你显示gbk的内容,所以就乱码了
你echo urlencode($s1);看看结果应该是每个汉字两字节的结果 %BA%DA%C9%AB,这个就是gbk的黑色。

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
