We can easily find the shortest path using the Floyd-Warshall algorithm, but we do not get the actual path to go from node X to Y. This is because the Floyd-Warshall algorithm does the calculation for the distance or cost and does not store the actual path for the minimum cost. For example, using Google Maps, we can always find a route to our destination from any given location. Google Maps can show us the best route as regards the distance, time of travel, or other factors. This is a perfect example of single source shortest path algorithm usage. There are many algorithms to find the solution for a single source shortest path problem; however, Dijkstra's shortest path algorithm is the most popular one. There are many ways to implement Dijkstra's algorithm, such as using Fibonacci heaps, min-heaps, priority...

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
