README

A blazing fast, type-safe, and fully tested sorted linked list library for PHP. Supports both integer and string values, with automatic sorting in ascending or descending order. Designed for performance, maintainability, and extensibility.

Features

• Automatic sorting (ascending/descending)
• Type safety: only one type per list (int or string)
• Fast insert, delete, contains, clear, and iteration Internal sorting logic (no external comparator needed)
• Simple, modern API

Installation

Install via Composer:

composer require vpinti/sorted-linked-list

Usage

use Vpinti\SortedLinkedList\SortedLinkedList;
use Vpinti\SortedLinkedList\Enum\SortOrder;

$list = new SortedLinkedList(SortOrder::ASC);
$list->insert(5);
$list->insert(2);
$list->insert(8);
$list->insert(1);

// Get sorted values as array
$values = $list->toArray(); // [1, 2, 5, 8]

// Check if a value exists
$list->contains(5); // true

// Remove a value
$list->delete(2);

// Iterate
foreach ($list as $value) {
    echo $value . PHP_EOL;
}

// Clear the list
$list->clear();

// Use with strings
$stringList = new SortedLinkedList(SortOrder::DESC);
$stringList->insert('banana');
$stringList->insert('apple');
$stringList->insert('pear');
// $stringList->toArray(); // ['pear', 'banana', 'apple']

API

SortedLinkedList

• __construct(SortOrder $order = SortOrder::ASC)
• insert(int|string $value): void
• delete(int|string $value): bool
• contains(int|string $value): bool
• clear(): void
• toArray(): array
• count(): int
• __toString(): string
• Iterator support (foreach)

Extensibility

Sorting logic is handled internally by the SortedLinkedList class. Custom comparators are not required or supported in this version.
