PHP Standards Recommendation - PSR

PSR stands for "PHP Standards Recommendation" and is a set of standardized recommendations for PHP development. These standards are developed by the PHP-FIG (Framework Interoperability Group) to improve interoperability between different PHP frameworks and libraries. Here are some of the most well-known PSRs:

  1. PSR-1: Basic Coding Standard: Defines basic coding standards such as file naming, character encoding, and basic coding principles to make the codebase more consistent and readable.

  2. PSR-2: Coding Style Guide: Builds on PSR-1 and provides detailed guidelines for formatting PHP code, including indentation, line length, and the placement of braces and keywords.

  3. PSR-3: Logger Interface: Defines a standardized interface for logger libraries to ensure the interchangeability of logging components.

  4. PSR-4: Autoloading Standard: Describes an autoloading standard for PHP files based on namespaces. It replaces PSR-0 and offers a more efficient and flexible way to autoload classes.

  5. PSR-6: Caching Interface: Defines a standardized interface for caching libraries to facilitate the interchangeability of caching components.

  6. PSR-7: HTTP Message Interface: Defines interfaces for HTTP messages (requests and responses), enabling the creation and manipulation of HTTP message objects in a standardized way. This is particularly useful for developing HTTP client and server libraries.

  7. PSR-11: Container Interface: Defines an interface for dependency injection containers to allow the interchangeability of container implementations.

  8. PSR-12: Extended Coding Style Guide: An extension of PSR-2 that provides additional rules and guidelines for coding style in PHP projects.

Importance of PSRs

Adhering to PSRs has several benefits:

  • Interoperability: Facilitates collaboration and code sharing between different projects and frameworks.
  • Readability: Improves the readability and maintainability of the code through consistent coding standards.
  • Best Practices: Promotes best practices in PHP development.

Example: PSR-4 Autoloading

An example of PSR-4 autoloading configuration in composer.json:

{
    "autoload": {
        "psr-4": {
            "MyApp\\": "src/"
        }
    }
}

This means that classes in the MyApp namespace are located in the src/ directory. So, if you have a class MyApp\ExampleClass, it should be in the file src/ExampleClass.php.

PSRs are an essential part of modern PHP development, helping to maintain a consistent and professional development standard.

echo $response->getBody(); // Response content

In this example, a GET request is sent to https://api.example.com/data and the response is processed.

Guzzle is a widely used and powerful library that is employed in many PHP projects, especially where robust and flexible HTTP client functionality is required.

 

 


Swoole

Swoole is a powerful extension for PHP that supports asynchronous I/O operations and coroutines. It is designed to significantly improve the performance of PHP applications by enabling the creation of high-performance, asynchronous, and parallel network applications. Swoole extends the capabilities of PHP beyond what is possible with traditional synchronous PHP scripts.

Key Features of Swoole

  1. Asynchronous I/O:

    • Swoole offers asynchronous I/O operations, allowing time-consuming I/O tasks (such as database queries, file operations, or network communication) to be performed in parallel and non-blocking. This leads to better utilization of system resources and improved application performance.
  2. Coroutines:

    • Swoole supports coroutines, allowing developers to write asynchronous programming in a synchronous style. Coroutines simplify the handling of asynchronous code, making it more readable and maintainable.
  3. High Performance:

  7. Timer and Scheduler:

    • With Swoole, recurring tasks and timers can be easily managed, allowing for efficient implementation of timed tasks.

Example Code for a Simple Swoole HTTP Server

<?php
use Swoole\Http\Server;
use Swoole\Http\Request;
use Swoole\Http\Response;

$server = new Server("0.0.0.0", 9501);

$server->on("start", function (Server $server) {
    echo "Swoole HTTP server is started at http://127.0.0.1:9501\n";
});

$server->on("request", function (Request $request, Response $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello, Swoole!");
});

$server->start();

In this example:

  • An HTTP server is started on port 9501.
  • For each incoming request, the server responds with "Hello, Swoole!".

Benefits of Using Swoole

  • Performance: Asynchronous I/O and coroutines allow applications to handle many more simultaneous connections and requests, significantly improving scalability and performance.
  • Resource Efficiency: Swoole enables more efficient use of system resources compared to synchronous PHP scripts.

PHP Attributes

PHP attributes were introduced in PHP 8, providing a way to attach metadata to classes, methods, properties, and other PHP entities. They allow developers to add declarative metadata in the form of attributes to code elements.

Syntax: Attributes are represented by an @ symbol followed by the attribute name, optionally including parentheses for parameters.

#[MyAttribute]
#[MyAttribute(parameter)]

Defining Attributes: Attributes are defined as classes marked with the [Attribute] suffix. These classes can have constructor parameters to pass additional data when applying the attribute.

#[Attribute]
class MyAttribute {
    public function __construct(public $parameter) {}
}

Applying Attributes: Attributes are then placed directly on classes, methods, properties, etc., to specify metadata.

#[MyAttribute('some_parameter')]
class MyClass {
    #[MyAttribute('another_parameter')]
    public $myProperty;

    #[MyAttribute('method_parameter')]
    public function myMethod() {}
}

Retrieving Attributes: You can use reflection to retrieve attributes on classes, methods, or properties and evaluate their parameters or other information.

$classAttributes = #[MyAttribute] get_attributes(MyClass::class);
$propertyAttributes = #[MyAttribute] get_attributes(MyClass::class, 'myProperty');
$methodAttributes = #[MyAttribute] get_attributes(MyClass::class, 'myMethod');

PHP attributes offer a structured way to integrate metadata directly into code, which is especially useful for conveying information like validation rules, access controls, documentation tags, and more in a clearer and declarative manner. They also facilitate the use of reflection to retrieve this metadata at runtime and act accordingly.
