Let’s make a simple summary of the recent PHP learning

Book: "PHP and MySQL Web Development"

Environment/Tools: wamp/Editplus&Chrome

Time: August 2nd - August 7th

Content:

I have learned the first 3 chapters before. The first 3 chapters are mainly about basic syntax and logical control statements, file access and processing, and arrays.

Chapter 4 Strings and Regular Expressions: Various functions for processing characters, the basics and applications of regular expressions.

Chapter 5 Code reuse and function coding: require and include functions, PHP function structure and usage, recursion.

Chapter 6 Object-oriented PHP: Object-oriented concepts and syntax, how to use private and public to control access, and how to implement inheritance.

Chapter 7 Error and Exception Handling: Concepts and control structures of exception handling, Exception class.

These 7 chapters are the basis of PHP (including object-oriented programming syntax), and they will be written below.

Chapter 8 Designing Web Database: In fact, it mainly introduces the concept of relational database (data logical structure is a two-dimensional table).

Chapter 9 Creating a Web Database: In fact, it mainly introduces how to log in to MySQL, how to create a MySQL user and set permissions, how to create database tables and data type settings.

Chapter 10 Using the MySQL database: the use of inert, select, update, alter table, delete, and drop statements (I think this is the key content of MySQL, especially the select statement, but unfortunately I don’t pay attention to it) .

Chapter 11 Using PHP to access the database from the Web: How to use PHP to establish a connection to the MySQL database (interfaces and methods for PHP to interact with the database).

Chapter 12 MySQL Advanced Management: Take a brief look at it, mainly talking about operation permissions and MySQL security. (Can’t quite understand...)

Chapter 13 Advanced MySQL programming: storage engine, transactions, foreign keys and stored procedures. (I can’t quite understand it either...)

Chapter 14 Operating an e-commerce website: Why build a website, risks and threats faced by the website. (Just learn about it)

Chapter 15 E-commerce security issues: main security threats, authentication principles, encryption technology foundation, digital certificates, etc. (Just learn about it)

Chapter 16 Web Application Security (I haven’t finished reading it yet, but after reading this, I think the writing is a bit verbose...)

To summarize: Chapters 1 to 7 are the basics of PHP, Chapters 8 to 11 are the basics of MySQL and PHP accessing databases, Chapters 12 and 13 MySQL advanced management and programming are a bit difficult (you can take a look at it personally), Chapter 14 ~ Chapter Just read Chapter 15 briefly.

Because I have always been interested in programming technology and thought it would be cool to make a website, so I kept learning. I have learned Java and C before, and I have also learned some Servlets and JSP in Web programming, but I have always learned it intermittently and have no practical experience.

In this book, I plan to read the first 18 chapters (the first half) and then stop for a while. The second half of the book is mainly about the advanced technical introduction and application of PHP. First, learn HTML, CSS and JavaScript (I have never paid much attention to it before), then combine the knowledge of the first 18 chapters to make a small website to practice, and then write a summary.

Today, my network is down. I wrote this using EditPlus. I will post it on my blog when the network is repaired.
August 2nd to August 7th at 20:28 pm.

PS: There was a problem when using basic authentication using the .htaccess file in Chapter 17. I searched on Baidu, but still don’t know how to start.

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.

The PHP vs. Python Debate: Which is Better?The PHP vs. Python Debate: Which is Better?Apr 16, 2025 am 12:03 AM

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: Handling Databases and Server-Side LogicPHP: Handling Databases and Server-Side LogicApr 15, 2025 am 12:15 AM

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.
