Node Creation
The first step in implementing a linked list is to define the structure of a node. Each node should contain the data it holds and a reference to the next node.
Syntax to Create Node
class ListNode {
public $data = NULL;
public $next = NULL;
public function __construct($data = NULL) {
$this->data = $data;
}
}
Implementation of Linked List in PHP
A linked list is a fundamental data structure in computer science, commonly used for efficient data management and manipulation. Unlike arrays, linked lists store elements in nodes that are not placed contiguously in memory, making them ideal for situations where the size of the data structure can change dynamically. Each node in a linked list contains the data and a reference (or link) to the next node in the sequence. This article will explore how to implement a basic linked list in PHP, including node creation, linked list creation, traversal, reverse traversal, and deletion of an element from the linked list.
