为什么[u4e00-u9fa5]不能匹配中文
用php的preg_match()函数匹配中文的时候,
匹配规则这么写,
$rule ='/[\u4e00-\u9fa5]/';
编译出错,说不知道\u,
该怎么办?
php怎么匹配utf-8编码的中文和gb2312编码的中文??
回复讨论(解决方案)
/[\x{4e00}-\x{9fa5}]/u
字符串需要unicode
gbk 和 utf-8是不一样的...utf-8很轻松的就可以匹配了...
测试了一下,
匹配出来时乱码。
function pregCh($test){ $rule ='/[\x{4e00}-\x{9fa5}]/u'; preg_match($rule,$test,$result); return $result; } $test ='asfasdhs中afhajs90中文8327849023'; var_dump(pregCh($test));
输出结果是
array(1) { [0]=> string(3) "涓?" }
页面编码是utf-8
为什么呢?
你的php文件自身是gbk编码
或者charset没有设为utf-8
你的php文件不是utf-8编码
哦,
确实是啊,
我用过的是notepad++
设置格式为utf-8,
结果匹配到的是乱码,
接了个header('Content-type:text/html;charset=utf-8');
就好了,
编辑器搞得是毛啊

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,

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.
