Use Composer to simplify PHP project development: Practical application of pxniu/study library

In my project, I need to perform SQL queries frequently, manage transactions, and perform dependency injection. If implemented manually, these tasks not only require writing a lot of code, but also prone to errors. After some searching, I found the pxniu/study library, which simplifies these operations through annotations, making my development process more efficient.

Install pxniu/study

Installing pxniu/study using Composer is very simple, just run the following command in the root of your project:

 <code class="bash">composer require pxniu/study</code>

How to use

1. SQL operation upgrade

The pxniu/study library simplifies SQL operations through method annotation. For example:

 <code class="php">@Select(sql = "select * from user where username = {username}") @Update(sql = "update user set price = price {price} where id = {id}") @Insert(sql = "insert into user (username, password, age, height, price, addtime) values ({username}, {password}, {age}, {height}, {price}, now())") @Delete(sql = "delete from user where id = {id}") @SelectOne(sql = "select * from user where id = {id}") @Update(sql = "update user set username = {username} where id = {id}")</code>

Parameters can be injected through {} , making SQL operations more intuitive and concise.

2. Transaction Management

Transaction management can also be implemented through method annotation:

 <code class="php">/** * @Transactional * 事务service */ function updateUser() { }</code>

In this way, transaction management becomes clearer and easier to maintain.

3. Dependency injection

The implementation of dependency injection is also very simple:

 <code class="php">class Index { /** * @Autowired(class = "\hyweb\service\Home\impl\UserServiceImpl") */ private $service; /** * @Autowired(class = "\hyweb\service\Home\impl\PayServiceImpl") */ private $payService; public function index() { echo Config::get("db.master", "host"); p($this->payService->getAll()); } }</code>

This method makes the code more modular and testable.

4. Conditional query

Conditional query can be implemented through if tag:

 <code class="php">/** * @Select(sql = "select * from role<if test="name != null"> where name like %{name}%</if> order by addtime desc limit {start}, {limit}") */ public function getAllByExcemples() { }</code>

This makes complex query conditions easier to manage.

5. Data loop insertion

Data loop insertion can be implemented through the foreach tag:

 <code class="php">/** * @Insert(sql = " insert into roles (roleId, permissionId) values<foreach collection="list" item="r" separator=","> ({roleId}, #id#})</foreach> ") */ public function adds() { }</code>

This method makes batch insertion of data more efficient.

Summarize

After using the pxniu/study library, I found that my project development efficiency has been greatly improved. Through annotation, SQL operations, transaction management, and dependency injection become more intuitive and concise. At the same time, the flexibility of the library also allows me to easily deal with various complex business needs.

In general, Composer not only simplifies the management and installation process of libraries, but also greatly improves the development efficiency and code quality of PHP projects through libraries like pxniu/study. If you encounter similar needs in development, you might as well try this library, and I believe you will find its power.
