坏狼的PHP学习教程之第1天
先培养对php的兴趣,就先了解php相对其他程序的优点.其实优点很多了.主要列举以下几点.
php能做任何事情,例如收集表单数据，生成动态网页，或者发送／接收 Cookies。但 PHP 的功能远不局限于此。
asp---------
1.微软平台,花钱买.
2.漏洞多.非开源,很多代码运行环境用法具体内容不公布.
3.效能差.服务器系统.
4.程式传写不结构化.
5.除错不容易.错误不好修改.
6.组件支持复杂多.
jsp---------
1.对硬件要求高.
2.要有java基础.
3.除错不容易.错误不好修改.
4.号称执行速度最快的.(通过编译加速,php也可以)
5.大型企业的商业模式较适合.(银行,企业.)
php---------
1.跨平台(microsoft,linux,unix)、跨web server(IIS，apache)
2.结构化(类似C)、除错容易.
3.效能机佳.
4.对硬体要求低.
5.源码公开、漏洞少、风险低.
6.支持的数据库广泛.
Adabas D InterBase PostgreSQL dBase FrontBase SQLite Empress mSQL Solid
FilePro（只读） Direct MS-SQL Sybase Hyperwave MySQL Velocis IBM DB2 ODBC Unix dbm
Informix Oracle（OCI7 和 OCI8） Ingres Ovrimos
其他:bbs、留言版、杂志、文章、架站机.甚至可以.....写命令列程式.写图形使用者界面.最重要不要钱。
php大概运行的环境:
服务器环境:apache+mysql+php+phpmyadmin 有个软件叫appserv.exe的集成这些.
使用的编写工具:Macromedia Dreamweaver 或 EmEditor等.
大概了解下php写的基本方式,PHP 的 echo() 语句显示了,大概4种写法：
最常见获取系统信息的
再写个自己初学测试的:
echo"买虚拟主机找坏狼！www.winshell.cn" //这里是php要写内容!
?>
基本先学这些了....主要的内容在以后呢....

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,
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.
What are PHP magic methods (__construct, __destruct, __call, __get, __set, etc.) and provide use cases?
Apr 03, 2025 am 12:03 AM
What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
PHP and Python: Comparing Two Popular Programming Languages
Apr 14, 2025 am 12:13 AM
PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.
PHP in Action: Real-World Examples and Applications
Apr 14, 2025 am 12:19 AM
PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.
PHP: A Key Language for Web Development
Apr 13, 2025 am 12:08 AM
PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
Explain the match expression (PHP 8 ) and how it differs from switch.
Apr 06, 2025 am 12:03 AM
In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
PHP vs. Python: Understanding the Differences
Apr 11, 2025 am 12:15 AM
PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
