初学新手问个正则的问题

Jun 23, 2016 pm 02:04 PM

研究好半天也没弄对

将 
/aaa/bbb/ccc

拆分成 
/aaa
/bbb
/ccc

我写的不对啊
preg_match('/(\/\w+)+/i', '/aaa/bbb/ccc', $matches);


回复讨论(解决方案)

一定要用正则吗,我觉得用explode函数也不错呀。

$str = '/aaa/bbb/ccc';$matches = explode('/',$str); //explodeecho '/'.$matches[1];  // /aaaecho '/'.$matches[2];  // /bbbecho '/'.$matches[3];  // /cccpreg_match_all('@\/[a-z]{3}@i', $str, $matches); //正则echo $matches[0][0];  // /aaaecho $matches[0][1];  // /bbbecho $matches[0][2];  // /ccc
Copy after login


要这样写
preg_match_all('/(\/\w+)/i', '/aaa/bbb/ccc', $matches);

$matches[1] 即是

3楼正解,是要匹配所有符合要求的,因此要用函数preg_match_all。

个人觉得没有必要去用正则,explode()完全可以做到你想要的结果,何必要舍近求远呢,当然也得看实际情况....

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,

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.
