How do I create a PHP library and publish it on Packagist?
如何创建 PHP 函数库并将其发布到 Packagist 上
1. 创建函数库
首先,创建一个新的 PHP 项目并使用 Composer 来管理依赖关系:
composer init
接下来,在 src 目录中创建一个新文件,例如 MyFunctions.php,并添加以下代码:
<?php namespace MyVendor\MyFunctions; function greet(string $name): string { return "Hello, $name!"; }
2. 创建 Composer.json 文件
在项目根目录中创建一个名为 composer.json 的文件并添加以下配置:
{ "name": "my-vendor/my-functions", "description": "A simple PHP function library", "authors": [ { "name": "Your Name", "email": "you@example.com" } ], "autoload": { "psr-4": { "MyVendor\\MyFunctions\\": "src/" } }, "minimum-stability": "dev" }
请确保将 "name" 属性替换为你的供应商/包名称。
3. 注册 Packagist 账户
转到 Packagist 网站并创建一个账户。
4. 创建包
登录到你的 Packagist 账户并创建新包。使用与 composer.json 文件中 "name" 属性相同的名称。
5. 提交你的函数库
切换到你的函数库本地项目的终端,然后执行以下命令:
composer login composer create-project --no-install my-vendor/my-functions [VENDOR/PACKAGE_NAME]
将 [VENDOR/PACKAGE_NAME] 替换为你在 Packagist 上创建的包的名称。这将在你的本地项目中创建一个新的克隆。
6. 签署包
你必须对你的包进行数字签名才能将其发布到 Packagist 上。为此,你需要一个 GPG 密钥。
若要生成 GPG 密钥,请运行以下命令:
gpg --gen-key
将 "Key-ID" 部分中的输出复制并粘贴到 Packagist 网站上你的包的 "Signer" 选项卡中。
7. 发布包
在你的本地项目中,运行以下命令:
cd [VENDOR/PACKAGE_NAME] composer install
这将安装创建项目所需的依赖关系。
接下来,将以下两行添加到 composer.json 文件的根目录:
"require": { "ext-zip": "*" }, "archive": { "exclude": [ "!src" ] }
最后,运行以下命令发布你的包:
composer config github-oauth.github.com <YOUR_GITHUB_ACCESS_TOKEN> composer run-script package
将
实战案例:
假设你有一个简单脚本,希望使用新创建的函数库来发送电子邮件。你可以按照以下步骤操作:
- 在你的脚本文件中,使用以下代码:
use MyVendor\MyFunctions\greet; $name = 'John Doe'; $greeting = greet($name);
- 运行你的脚本。稍后,你将看到以下输出:
Hello, John Doe!

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

I had a tough problem when working on a project with a large number of Doctrine entities: Every time the entity is serialized and deserialized, the performance becomes very inefficient, resulting in a significant increase in system response time. I've tried multiple optimization methods, but it doesn't work well. Fortunately, by using sidus/doctrine-serializer-bundle, I successfully solved this problem, significantly improving the performance of the project.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

When developing an e-commerce website, I encountered a difficult problem: how to provide users with personalized product recommendations. Initially, I tried some simple recommendation algorithms, but the results were not ideal, and user satisfaction was also affected. In order to improve the accuracy and efficiency of the recommendation system, I decided to adopt a more professional solution. Finally, I installed andres-montanez/recommendations-bundle through Composer, which not only solved my problem, but also greatly improved the performance of the recommendation system.

When developing an e-commerce platform, it is crucial to choose the right framework and tools. Recently, when I was trying to build a feature-rich e-commerce website, I encountered a difficult problem: how to quickly build a scalable and fully functional e-commerce platform. I tried multiple solutions and ended up choosing Fecmall's advanced project template (fecmall/fbbcbase-app-advanced). By using Composer, this process becomes very simple and efficient. Composer can be learned through the following address: Learning address

The Laravel framework has built-in methods to easily view its version number to meet the different needs of developers. This article will explore these methods, including using the Composer command line tool, accessing .env files, or obtaining version information through PHP code. These methods are essential for maintaining and managing versioning of Laravel applications.

When developing a Laravel application, I encountered a common but difficult problem: how to improve the security of user accounts. With the increasing complexity of cyber attacks, a single password protection is no longer enough to ensure the security of users' data. I tried several methods, but the results were not satisfactory. Finally, I installed the wiebenieuwenhuis/laravel-2fa library through Composer and successfully added two-factor authentication (2FA) to my application, greatly improving security.

I'm having a tricky problem when developing a Symfony-based application: how to effectively validate JSON data format. Initially, I tried using manual verification code, but this was not only complicated, but also error-prone. After some exploration, I discovered a Composer package called ptyhard/json-schema-bundle, which brought great convenience and efficiency to my project.
