Overview of this book

PHP has always been the the go-to language for web based application development, but there are materials and resources you can refer to to see how it works. Data structures and algorithms help you to code and execute them effectively, cutting down on processing time significantly. If you want to explore data structures and algorithms in a practical way with real-life projects, then this book is for you. The book begins by introducing you to data structures and algorithms and how to solve a problem from beginning to end using them. Once you are well aware of the basics, it covers the core aspects like arrays, listed lists, stacks and queues. It will take you through several methods of finding efficient algorithms and show you which ones you should implement in each scenario. In addition to this, you will explore the possibilities of functional data structures using PHP and go through advanced algorithms and graphs as well as dynamic programming. By the end, you will be confident enough to tackle both basic and advanced data structures, understand how they work, and know when to use them in your day-to-day work

Using Linked Lists

We know a lot about arrays already. Now, we are going to shift our focus to a new type of data structure known as a list. It is one of the most used data structures in the programming world. In most of the programming languages, the array is a fixed size structure. As a result, it cannot grow dynamically, and shrinking or removing an item from a fixed size array is also problematic since we have to shift the array's items to fill up the gap. For this reason, many developers prefer lists instead of arrays. Considering the fact that each array element can have an overhead of some extra bytes, linked lists can be used where memory efficiency is a big factor. In this chapter, we will explore the different types of linked lists in PHP and their implementation. We will also look at real-world problems that can be solved using linked lists.
