PHPAlgorithms

A collection of common algorithms implemented in PHP. The collection is based on "Cracking the Coding Interview" by Gayle Laakmann McDowell

You can find the package on Packagist: https://packagist.org/packages/doganoo/php-algorithms

Why Using PHPAlgorithms?

"Algorithms + Data Structures = Programs"

Algorithms are a part of the basic toolkit for solving problems. Data Structures organize data in an efficient way. The combination of both allow the creation of smart and efficient software.

Installation

You can install the package via composer:

composer require doganoo/php-algorithms

Usage

Here's an Binary Tree example:

use doganoo\PHPAlgorithms\Datastructure\Graph\Tree\BinaryTree;

$binaryTree = new BinaryTree();
$binaryTree->insertValue(50);
$binaryTree->insertValue(25);
$binaryTree->insertValue(75);
$binaryTree->insertValue(10);
$binaryTree->insertValue(100);

echo json_encode($binaryTree);

produces

{"nodes":{"value":50,"left":{"value":25,"left":{"value":10,"left":null,"right":null},"right":null},"right":{"value":75,"left":null,"right":{"value":100,"left":null,"right":null}}}}
