PHP字符编码问题之GB2312 VS UTF-8
今天照着书随便写了段代码,代码意图是将字符串使用str_split()函数进行分割成数组,英文好说,但分割中文(两个中文一个数组单元)时就出问题了——
看代码:
>http://www.w3.org/TR/html4/loose.dtd">
$string1 = "i am a phper";
$string2 = "这本书是蓝海战略";
print_r(str_split($string1));
echo "
";
print_r(str_split($string2,4));
?>
测试结果打出我所料——中文乱码
Why?Why?Why?Why?乱码是什么?什么事乱码?给我解释解释,什么,是%&的乱码!
因为英文无乱码,只有中文乱码,首先想到了编码的问题,于是突然想起来UTF-8的编码是UTF-8需要3个字节,死马当活马医吧!
于是 print_r(str_split($string2,4));这句中的4 ,就被换成了6,于是乎——看结果
同样,你也可以试试将编码的charset的UTF-8改成GB2312,因为Unicode的编码是需要2字节的,所以说Gb2312的编码比UTF-8能够节约1/3的空间,但是如果你要兼容繁体中文、韩文、日文的其他的语言就需要使用UTF-8了。
顺便发现了首动感的Music,拿来分享一下:

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,
