Sending Emails with PHP
Article Introduction：Core points
PHP provides an easy and efficient way to send emails, including basic plain text messages, HTML messages, and mail with attachments.
PHP's mail() function is used to send emails. For simple emails, it only requires three parameters: the address of the recipient, the subject, and the body of the email.
When sending HTML messages or messages with attachments, you need to use the MIME standard to break the messages into sections and separate them with selected boundaries. Each section should define what the content is, how it is encoded, how the content is handled, and the content itself.
Use the PHPMailer library to enhance the functionality of sending mail in PHP, which allows connections to SMTP services

Difference between Inheritance and Interface in Java
Article Introduction：Inheritance and interface in Java are two different code organization methods, which are used to create hierarchies between classes and implement code reuse. Inheritance creates subclasses by copying the properties and methods of the parent class, while the interface defines a set of method signatures, which are implemented specifically by the implementation class. This article will explain the key differences between the two and illustrate them with Java code examples.
Code Example
The following code demonstrates the interface and inheritance application:
C.add(5, 10);
C.subtract(35, 15);
C.multiply(6, 9);
C.divide(45, 6);
Output result:
The result is here. Have A Look:

Magic Methods and Predefined Constants in PHP
Article Introduction：Core points
PHP provides predefined constants and magic methods to enhance code functionality. Predefined constants provide read-only information about code and PHP, while magic methods are names reserved in the class to enable special PHP features.
Predefined constants (all capital letters enclosed with double underscores) provide information about the code. Examples include __LINE__ (returns the line number in the source file), __FILE__ (represents the file name, including its full path), __DIR__ (represents the file path only), __CLASS__ (returns the name of the current class), __FUNCTION__ (returns the name of the current function), __METHOD__ (represents the name of the current method), and

PHP Master | The MVC Pattern and PHP, Part 1
Article Introduction：Detailed explanation of Model-View-Controller (MVC) architecture model and PHP implementation examples
Core points
The MVC pattern is a software architecture pattern that separates the display of data from the methods of interacting with the data, allowing front-end and back-end developers to work on the same system without interfering with each other.
Because of its emphasis on separation of concerns and reusable code, MVC has been applied to web development, which encourages the development of modular systems to quickly update, add or delete features.
The MVC pattern contains three core parts: Model, View, and Controller. The model is the permanent storage of data, and the view is to view the data and determine its best

php add 6 months to date
Article Introduction：In PHP, add 6 months to date. The commonly used method is to use the DateTime class with the modify() or add() method. 1. Use modify('6months') to achieve rapid implementation, but may jump when processing the end of the month. For example, 2024-03-31 plus six months will become 2024-09-30; 2. Use add(newDateInterval('P6M'))) to be more flexible and controllable, suitable for complex logic; 3. If you need to retain the "end of the month" semantics, you can adjust them in combination with modify('lastday of thismonth'); 4. Pay attention to the uniform time zone settings and date formats, and it is recommended to use YYYY-MM-DD to avoid parsing errors.
