PHP模板引擎
PHP开发程序,通常都是php代码和html混编在一起,那么这样有什么问题呢?
首先,不利于分工合作。一般来说,都会由程序员来写代码,美工人员设计页面。那么在这种方式中,程序员必须等待美工人员把界面设计好才能开始工作。也就是说程序员和美工的工作是不能同步的。
其次、不利于维护,可维护性差。比如说程序固定后,要修改界面,那么必须由美工修改后,程序员再重新添加。
最后,程序结构混乱,可读性差。HTML和PHP混编在一起,一旦程序一多,就会变的非常的凌乱。
模板技术正是为了解决这些问题而出现的,为了解决这些问题,最早出现的是使用php标签的模板技术。
1. 解释型的 PHPLIB
(1)程序处理过程
$t = new Template()
$t->set_file
$t->set_var
$t->parse
$t->p
翻译成中文就是
初始化模板类$t 设置模板文件 设置模板变量 分析模板文件中的模板变量 输出内容通过了最少5个步骤在php程序中实现模板的处理
(2)处理循环嵌套:
{it}
2. 编译型的 Smarty 的程序处理过程
(1)程序处理过程:
$s = new Smarty
$s->assign
$s->display
翻译成中文就是
初始化模板类 设置模板变量 解析并输出模板(2)处理循环嵌套:
(当然还有foreach这样的)
总结:
PHP不需要非常精通的语法;PHP不需要你自己去开发众多的库;PHP不需要你去为性能、稳定性等语言自身的特性而担心。
PHP需要的是你的逻辑;PHP需要的是你的创造力;PHP需要的是你的思想!!!

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.
