Here's an example of a high-level algorithm in PHP using OOP to illustrate the concept described in this Tweet https://x.com/CodeWithCaen/status/1824869764696592676

class DocumentProcessor {
    private $document;
    private $analyzer;
    private $transformer;
    private $validator;
    private $publisher;

    public function __construct(
        Document $document,
        Analyzer $analyzer,
        Transformer $transformer,
        Validator $validator,
        Publisher $publisher
    ) {
        $this->document = $document;
        $this->analyzer = $analyzer;
        $this->transformer = $transformer;
        $this->validator = $validator;
        $this->publisher = $publisher;
    }

    public function process(): void {
        $this->preprocessDocument()
             ->analyzeContent()
             ->transformContent()
             ->validateResults()
             ->publishDocument();
    }

    private function preprocessDocument(): self {
        // Implementation details to be filled later
        return $this;
    }

    private function analyzeContent(): self {
        $this->analyzer->analyze($this->document);
        return $this;
    }

    private function transformContent(): self {
        $this->transformer->transform($this->document);
        return $this;
    }

    private function validateResults(): self {
        $this->validator->validate($this->document);
        return $this;
    }

    private function publishDocument(): self {
        $this->publisher->publish($this->document);
        return $this;
    }
}

This example demonstrates:

1. A high-level algorithm for processing a document.

2. The main algorithm body is declared fluently in the process() method.

3. Implementation details are left to helper methods and collaborating objects.

4. The use of interfaces (implied by the type hints) allows for flexibility in the actual implementations.

This code structure allows you to outline the main steps of your algorithm without getting bogged down in the details of each step, which can be implemented later or in separate classes.
