How to simplify email marketing with Composer: DUWA.io's application practices
Article Introduction：I'm having a tricky problem when doing a mail marketing campaign: how to efficiently create and send mail in HTML format. The traditional approach is to write code manually and send emails using an SMTP server, but this is not only time consuming, but also error-prone. After trying multiple solutions, I discovered DUWA.io, a simple and easy-to-use RESTAPI that helps me create and send HTML mail quickly. To further simplify the development process, I decided to use Composer to install and manage DUWA.io's PHP library - captaindoe/duwa.

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

php get number of days in month
Article Introduction：How to use PHP to get the number of days in a certain month? 1. Use the cal_days_in_month function, which is the most direct way. The syntax is cal_days_in_month(CAL_GREGORIAN, $month, $year); 2. Use the DateTime class and modify method to create the first day of the month and get the date of the last day by adding one month and subtracting one day. Both methods can correctly obtain the number of days. The former is simple and suitable for simple needs, while the latter is suitable for scenarios where DateTime operations are already available or requires more time to process.

Memory Performance Boosts with Generators and Nikic/Iter
Article Introduction：PHP iterator and generator: a powerful tool for efficient processing of large data sets
Arrays and iterations are the cornerstone of any application. As we get new tools, the way we use arrays should also improve.
For example, a generator is a new tool. At first we only have arrays, and then we gain the ability to define our own class array structure (called iterators). But since PHP 5.5, we can quickly create class iterator structures called generators.
Generators look like functions, but we can use them as iterators. They provide us with a simple syntax for creating essentially interruptible, repeatable functions. They are amazing!
We will look at several areas where generators can be used and explore the need to note when using generators

how to deep copy a php array
Article Introduction：There are three ways to implement deep copy of arrays in PHP: First, use unserialize and serialize to disconnect references by serializing and deserializing, which is suitable for ordinary and nested arrays; second, object arrays combine clone and recursive functions to flexibly process mixed types but ensure that the class supports correct cloning; third, json_encode and json_decode are suitable for pure scalar data, with simple writing but no resources or special objects.

php how to get current year
Article Introduction：Getting the current year can be achieved in PHP through two main methods. 1. Use the date('Y') function to directly output four-digit years, which is suitable for simple scenarios; 2. Use the DateTime class for object-oriented processing, which is suitable for complex projects. Note: To avoid time zone problems, it is recommended to explicitly set the time zone, such as Asia/Shanghai, through date_default_timezone_set() or DateTimeZone, to ensure accurate results.

Re-Introducing Symfony Console - CLI PHP for the Uninitiated!
Article Introduction：Core points
Symfony Console is a standalone package that provides a simple framework for creating command line tools, which is useful for repetitive tasks such as data migration, importing, or creating cron jobs.
To create a new command, you need to make the file executable. This can be done by creating a console file in the project root directory, ensuring the file is executable, and defining the console application.
You can use Symfony's CommandTester class to test commands, which provides special input and output classes to test commands without the command line.
Symfony Console is installed using Composer (the dependency management tool in PHP). It provides a simple

Article Introduction：There are three main ways to convert date formats in PHP. 1. Use date and strtotime to combine to be suitable for simple conversion in standard formats, such as converting yyyy-mm-dd to dd-mm-yyyy; 2. Use the DateTime class to be suitable for handling complex scenarios such as addition and subtraction days or object-oriented style development; 3. Non-standard formats can be regularly extracted or introduced into third-party libraries such as Carbon to parse and format output.

How to implement array LRU cache in PHP?
Article Introduction：Implementing LRU cache in PHP can simulate bidirectional linked list structure by using associative arrays and index arrays. The specific steps are as follows: 1. Create an LRUCache class and initialize an array of capacity, cache and access order. 2. Implement the get method, return the value and update the access order. 3. Implement the put method, add or update elements, and remove the longest-lasting elements if necessary. This method is simple and easy to understand, but performance may decline under large data volumes.
