We can see that the smarty program Part of it is actually a set of codes that comply with the PHP language specifications. Let’s explain them in turn:
1. /**/Statement:
The included part is the program header comment. The main content should be a brief introduction to the function of the program, copyright, author and writing time. This is not necessary in smarty, but in terms of the style of the program, this is a good style.
2. include_once statement:
It will include the smarty file installed on the website into the current file. Note that the included path must be written correctly.
3. $smarty = new Smarty():
This sentence creates a new Smarty object $smarty, which is a simple instantiation of an object.
4. $smarty->templates(""):
This sentence specifies the path when the $smarty object uses the tpl template. It is a directory. Without this sentence, Smarty's default template path is the templates
directory of the current directory. The actual directory When writing a program, we should write this sentence clearly. This is also a good programming style.
5. $smarty->templates_c(""):
This sentence specifies the directory where the $smarty object is compiled. In the template design chapter, we already know that Smarty is a compiled template language, and this directory is the directory where it compiles templates. Note here that if the site is located on a *nix server, please ensure that the directory defined in teamsplates_c has a valid Write-readable permissions. By default, its compilation directory
is templates_c in the current directory. For the same reason, we write it out explicitly.
6. $smarty->left_delimiter and $smarty->right_delimiter:
Indicates the left and right delimiters when looking for template variables. By default, it is "{" and "}", but in practice, because we need to use

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.
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.

Explain late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
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.
