PHP Data Structures Example

This PHP project demonstrates the implementation of various data structures using object-oriented programming principles.

Overview

This project includes the implementation of a doubly linked list data structure in PHP. The main file (index.php) demonstrates the functionality of the doubly linked list through an example usage scenario.

How It Works

Index File (index.php)

The index.php file serves as the entry point to demonstrate the functionality of the implemented data structures. It showcases the usage of a doubly linked list through the ShouldHandle interface and DataStructuresFacade.

Code Explanation

<?php
use As984\DataStructures\Contracts\ShouldHandle;

require_once __DIR__ . '/vendor/autoload.php';

return new class implements ShouldHandle
{
    public function __construct()
    {
        $this->handle();
    }

    public function handle(): void
    {
        // Create a new LinkedList instance
        $data = (new As984\DataStructures\Facade\DataStructuresFacade)->linkedList();

        // Push some initial data into the linked list
        $data->push(1);
        $data->push(2);
        $data->push(3);

        // Use pushAfter method to insert new data after node with data 1
        $data->pushAfter(1, 4);

        // Use pushBefore method to insert new data before node with data 1
        $data->pushBefore(1, 98);

        // Remove node with data 1
        $data->remove(1);

        // Print the Linkedlist 
        $data->printList();
    }
};
?>

Usage

To run the code:

1. Ensure PHP 8.0 or later is installed.
2. Install dependencies by running composer install.
3. Execute the following command in your terminal or command prompt:

php ./index.php
