已经开始学php一个多月了,但是发现看书进度有点慢,请问直接看视频教程跟看书,哪个效率高点呢?求大牛指导......
回复讨论(解决方案)
我也是刚学,觉得先把配置问题解决,然后看书比较快,主要是练习!你用的apache哪个版本?配置解决了?
我觉是看完基本的PHP语法后,可以看看开源的代码,自己尝试写写
平时要多看官方的手册,不懂就查询。
是的,配置环境都搭建完事了,就是想提高学习的效率,不知道哪种方式比较好。所以才求指导,嘿嘿......
我感觉是缺一不可,理由:
一般的视频教程注重的是对实际的操作训练或对基本概念的检验,
主要建立学习的自信心或引发再学习的动力,也是检验理论知识的一个机会。
一般的书注重的是基本知识的讲解或对语言本质的探索,
主要建立对语言基础范围的认识或应付变态的各种面试。
这两个搭配才能使学习是一个持续或再循环的过程,从书上面建立大体的认知,从视频上学会检验认知。
做一些感兴趣额小例子,这样寓教于乐,学的还快!
入门的时候php+mysql带着学,增删改学会了,你就算入门了。
看书还是看视频,找一个适合自己的就行,主要是多敲代码,多练习!
应该配合使用,先看书,再看视频,然后练习。
买一本好书,快速看第一遍,第二遍边看边练习书上的代码,看视频会容易睡着的。
你可以去我的博客找找你要的资源。。。www.xuecaijie.com
看什么都没有多大作用!
首先学会用人类语言准确的描述自己的问题
其次学会用机器语言(比如php)准确的描述自己的问题
你是机器的主人,而不是机器的奴隶
我觉着只有实践才能锻炼出大牛!!!!!

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
