Is PHP in demand? Is it worth being a PHP developer in 2023?
Such queries are common among budding developers, especially after a slight decline of PHP-based websites in 2022, from 78.9% to 77.5% in 2023, per W3Techs report. However, PHP still has a fair share of holding in the market. Since it’s faster, better, quick to learn, and flexible, it has broader scope among web developers. Also, the long list of PHP-based frameworks – Laravel, Symfony, CodeIgniter, CakePHP, Phalcon, and Laminas- can ensure that PHP is not going anywhere.
The PHP community is constantly working to improve the framework and core PHP functionalities to make rich libraries for its dependent frameworks. In Dec 2022, PHP launched its latest version, 8.2, and its newer version targeting RFCs is set to be released by the end of 2023. So, all these facts answer well is PHP in demand.
As several frameworks are based on PHP, the need for a structured approach to resolving common software design problems comes. PHP’s design patterns and service patterns serve as a proven solution to this challenge. It helps developers in building maintainable, scalable, and reusable code for different use cases. This blog will guide you more about PHP service and design patterns.
Is the PHP service pattern and PHP design pattern the same?
Each service pattern is a design pattern, but the opposite is untrue. An interesting fact is that service patterns are a subset of design patterns specifically focused on managing service dependencies. In contrast, design patterns cover a broader range of solutions to common design problems. If the service pattern is also a design pattern, how is it different? Let me tell you:
PHP Design Patterns are reusable solutions to developers’ common design problems during software development. These are code structuring patterns that aid scalability, flexibility, and maintainability. The broad categorisation of design patterns includes creational, structural, and behavioural patterns.
Whereas the PHP service pattern is specific to service-oriented applications’ specific design and architecture. It provides guidelines for designing and implementing services to achieve loose coupling, scalability, and interoperability. The terms PHP service patterns and PHP service layer patterns are often used interchangeably in PHP. Service patterns can refer to patterns such as Service Locator, Dependency Injection (DI), or Inversion of Control (IoC) containers.
What is the difference between Service Locator, Dependency Injection (DI), and Inversion of Control (IoC) containers? Read on more to learn about each of these PHP service patterns.
What is PHP service Pattern? What are their benefits?
It is a design pattern that focuses on organising and managing the business logic of an application. It helps separate the application’s business logic from the presentation layer (user interface) and the data access layer. Moreover, it promotes the principle of “Separation of Concerns,” where each application layer has specific responsibilities.
When implementing the Service Pattern in PHP, you can create service classes that contain methods representing various operations and business logic. Then, the presentation layer can invoke these services to perform specific tasks.
Benefits of using PHP service patterns
Business Logic Encapsulation:
The application’s complex business logic and operation is contained in the service layer that abstracts it from the presentation layer. This interface provides a clean and organised way of interacting with the underlying business rules.
Reusability and Modularity:
The business logic centralisation in a service layer lets you reuse the services across different application parts. Such a service pattern promotes modularity and minimises code duplication.
Code Organisation:
It helps organise the application’s logic into meaningful services. Each service focuses on a specific domain or functionality, making the codebase more maintainable and understandable.
Dependency Management:
The Service Layer can manage the dependencies the business logic requires. This can include interactions with data repositories, external services, or other dependencies. It helps decouple the business logic from the underlying implementations, promoting flexibility and testability.
Business Rules Enforcement:
Consider the service layer as a central hub to enforce business rules and validations. It ensures that the application follows the defined rules and constraints, promoting consistency and integrity.
List of PHP Service Patterns
Service Locator:
It manages and retrieves dependencies or services throughout an application. It provides a centralised registry or container for locating and accessing these services. Here’s how the service locator pattern is implemented in PHP:
