<code> 本人php入行差不多快3年了,平时都是写业务逻辑功能, 渴望技术能够提升一个层面,想学好面向对象,设计模式。 于是入手了《Learning PHP设计模式》,但是无论我怎么看, 都还是觉得想天书一样,是否由于我基本功不够,挑选错书籍来学习, 希望大神们能够指导一下,推荐先学习的书籍。 面试的时候,被别人问及面向对象和设计模式的问题, 完全没法回答,作为一个入行快3年的phper来说,太丢脸了!!!! </code>

推荐一本图灵黑色封皮的书,我看了下觉得比较容易理解深入PHP:面向对象、模式与实践
面向对象其实是比较抽象的东西,加上不像原生代码那样的平铺下来,类继承,复用,你看的话跳跃性比较大,一会发现有个貌似在本文件里没有定义的方法出现,容易有眩晕感。
我的建议,1 要搞清楚对象的基础,知道各种基础含义(比如静态变量,析构函数)
<code> 2 要知道怎么找一个类一个方法(借助一些IDE工具去看代码会容易点) 3 大部分书和教程对对象的解释也很抽象,新手难以理解,通俗的说对象就是一个人,类就是这个人的嘴巴,鼻子,方法就是用嘴吃饭。</code>
先了解为什么要面向对象,现在写的代码是不是不好维护,有什么方法可以解决,面向对象的一些特性是不是正好可以解决这些问题,结合实际的问题再去研究,就比较好理解了。
刚好最近看了几篇关于设计模式的文章,问主参考下看看。希望对你有帮助:)
首先得有个对象

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
