php 多语言 sql 要怎么写
每一个函数我都要判断$_SESSION['language']的值,可以怎么优化?
public function getA(){ if($_SESSION['language']=="tc"){ $sql="select a_tc from table"; }elseif($_SESSION['language']=="en"){ $sql="select a_en from table"; } } public function getB(){ if($_SESSION['language']=="tc"){ $sql="select b_tc from table"; }elseif($_SESSION['language']=="en"){ $sql="select b_en from table"; } }
回复讨论(解决方案)
即然language是字段的一部分,直接拼接成SQL就行了
你可以优化表,设置一个语言字段,通过$_SESSION['language']取数据:
select content from table where language = $_SESSION['language']
这样不管后面来多少种语言都迎刃而解了,可扩展性好
$sql = "select a_$_SESSION[language] from table";
但需要指定默认值,第一次进入时是没有 $_SESSION['language'] 的
不过你的代码也没有进行处理
#2 的方案是不妥当的
1、冗余量太大
2、不易产生对照

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,

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.
