求助下。怎么把a=ddddd&page=1111中的page=1111这样的删去呢。

Jun 23, 2016 pm 02:14 PM

这是个url地址,截取出来的参数串。

a=ddddd$page=2334&www=2222
page=1111&m=3234&o=r2345
a=ddddd$wc=2334&page=plo

这三种都有可能。前面,中间,最后。

怎么正则把page=参数值,干掉呢。

我鼓秋了半天正则,写出来个这。page=.*&|\s,还是不行,匹配不出来。

高手指点一下啊。

$s = 'a=ddddd&page=2334&www=2222';$s = 'page=1111&m=3234&o=r2345';$s = 'a=ddddd&wc=2334&page=plo';//这样比较正规parse_str($s, $a);unset($a['page']);echo http_build_query($a), PHP_EOL;//正则比较另类echo preg_replace('/(&?)page=[^&]+(&?)/e', '"$2"?"$1":""', $s);

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
