//比如现在有个数组$arr=array('语文'=>'yw','数学'=>'xx','英语'=>'yy','物理'=>'wl');//php接收用户输入的一段文字//假如为"英语好难啊,数学好简单"//那么我需要在这段文字中找出是否存在在数组中的key,即英语跟数学 ,得到他们对应的value值.//大概就是这样一个功能.

首先得分词
完后再匹配
分词有扩展模块 可以试一下.
这是关键字匹配,与分词没什么关系
$arr = array('语文'=>'yw','数学'=>'xx','英语'=>'yy','物理'=>'wl');$txt = "英语好难啊,数学好简单";foreach($arr as $k=>$v) $p[] = "/$k/e";preg_replace($p, '$res["$0"]=$arr["$0"]', $txt);print_r($res);
(
[数学] => xx
[英语] => yy
)

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,

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

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.
