Date processing library in PHP8.0: Carbon

PHP language has always been one of the most popular languages ​​in the field of web development. Due to its ease of learning and use, powerful functions and wide support, PHP development has become the first choice for website development and implementation of web applications.

During web application development, date and time handling is often a basic task that must be considered. Deciding how to handle date and time data often depends on the needs and requirements of the application, so libraries for date and time calculations in PHP are very important.

In this article, we will introduce the newly released date and time processing library for PHP8.0: Carbon. Carbon is a powerful date and time calculation library that provides many useful functions and methods to simplify tasks such as basic date and time calculations.

1. Introduction to Carbon

Carbon is a third-party library for PHP that is used to handle date and time calculations, providing more flexibility and easier-to-use date and time operations. Function. Carbon can handle many common date and time formats, such as ISO8601 and RFC2822.

The advantages of Carbon are:

1. Using Carbon in PHP, it is easy to handle complex date and time calculation tasks.
2. Supports many date and time formats, allowing developers to better process and display date and time data as needed.
3. Simplify the code, improve code readability, and save development time.

2. Carbon installation

To use Carbon, you need to install it first. Carbon can be installed through Composer. Open the root folder of your project in a terminal and install it using the following command:

composer require nesbot/carbon

composer will automatically download Carbon and add it to your project, which allows you You can use it immediately.

3. Using Carbon

Using Carbon is very simple. It provides various methods to handle date and time data. Here are some examples:

1. Create Carbon instance

use CarbonCarbon;

$now = Carbon::now();
$today = Carbon::today();
$yesterday = Carbon::yesterday();
$tomorrow = Carbon::tomorrow();
$nextWeek = Carbon::now()->addWeek();
$lastMonth = Carbon::now()->subMonth();

In the above example, the now() method creates a Carbon instance of the current date and time; today() and yesterday() ) returns today's and yesterday's Carbon instances; tomorrow() returns tomorrow's Carbon instance; addWeek() and subMonth() methods can add or subtract days or months to the current date.

2. Format date and time

Carbon provides many methods for formatting date and time, such as format() and diffForHumans() methods.

use CarbonCarbon;

$now = Carbon::now();
echo $now->format('Y-m-d H:i:s'); // 返回 2022-06-20 15:38:22

$nextWeek = Carbon::now()->addWeek();
echo $nextWeek->diffForHumans(); // 返回 1 week after

In the above example, the format() method is used to convert the Carbon instance to the specified date and time format; the diffForHumans() method returns the humanized time between the two dates.

3. Get date and time

Carbon provides many methods to get date and time information, such as year(), month(), day(), hour() and minute() etc.

use CarbonCarbon;

$now = Carbon::now();
echo $now->year; // 返回 2022
echo $now->month; // 返回 06
echo $now->day; // 返回 20
echo $now->hour; // 返回 15
echo $now->minute; // 返回 44

In the above example, the Carbon instance provides many methods for obtaining date and time information, allowing you to quickly obtain the information you need.

4. Summary

Carbon is a powerful PHP date and time processing library that provides many useful date and time operation functions. Using Carbon, you can simplify your code, improve code readability, and save development time. In future PHP project development, using Carbon will be a very efficient task.
