1. What is an ORM framework?
ORM stands for Object Relational Mapping, which is a programming technology used to map data in the database to objects in the program. The ORM framework is a solution that encapsulates ORM technology into a framework and provides a series of methods and classes to operate the database. The main purpose of the ORM framework is to simplify database operations and improve code readability.
2. What are the common ORM frameworks for PHP?
In the field of PHP, there are many ORM frameworks, among which the more commonly used ones are PDO, Doctrine, Eloquent and RedBeanPHP.
PDO stands for PHP Data Objects. It is a lightweight ORM framework officially provided by PHP and can interact with a variety of databases, including MySQL. , PostgreSQL, Microsoft SQL Server and Oracle, etc. PDO encapsulates a series of methods, which is relatively simple to operate and highly portable.
Doctrine is one of the most well-known ORM frameworks in the PHP field and is widely used in popular PHP frameworks such as Symfony and Zend Framework. Doctrine provides the definition and use of Entity classes, configuration through annotations or XML, and supports a variety of databases, including MySQL, PostgreSQL, Oracle, SQL Server, NoSQL and in-memory databases.
Eloquent is the ORM framework used by default in the Laravel framework and is also a very popular framework. Eloquent provides the Active Record design pattern, allowing developers using this framework to operate databases like objects, supporting a variety of databases, including MySQL and SQLite.
RedBeanPHP is a lightweight ORM framework that supports many popular database systems, such as MySQL, PostgreSQL, SQLite and Oracle. RedBeanPHP can automatically create and manage tables, so developers do not need to worry about table management, and it also provides a simple and easy-to-use API for operation.
3. Why is it recommended to use Eloquent?
Although ORM frameworks such as PDO, Doctrine and RedBeanPHP have their own advantages, in most cases, Eloquent is still our recommended ORM framework for the following reasons:
Eloquent provides developers with a set of simple and easy-to-use APIs. By using PHP's dynamic method calls, developers can directly use table names to operate objects.
Eloquent supports multiple database types and is highly scalable. It also supports many common operations, such as query, aggregation, and joint table query. wait.
Laravel is a very active community, and Eloquent, as an important part of it, has been widely used and updated, so it will continue to be used in the future. You can look forward to updates and improvements to Eloquent.
4. Summary
As a very popular programming language, PHP also has many choices in the field of ORM framework. Although each framework has its advantages and disadvantages, we strongly recommend using Eloquent. Its simplicity, ease of use, flexibility, and active community can greatly improve development efficiency and code readability.
