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

Built-in support through PECL

Since PHP 7.0 release, a raising concern for developers is the performance issue of SPL classes. PHP 7.0 does not bring any improvement to early designed SPL classes, and many developers are now sceptical about using it further. Many developers have written custom libraries and extensions for PHP to improve the data structure efficiency. One of such extensions is PHP DS, a specialized extension for PHP 7 data structures. The extension is written by Joe Watkins and Rudi Theunissen. The official documentation of PHP DS extension can be found in the PHP manual at http://php.net/manual/en/book.ds.php.

The library works as an alternative to PHP array, which is a very flexible, dynamic, hybrid data structure. This extension comes up with lots of pre-built data structures such as set, map, sequence, collection, vector, stack, queue, priority queue, and so...
