Hash table can be a very efficient data structure when it comes to search operations. Since hash tables store data in an associative manner, if we know where to look for the data, we can easily get the data quickly. In the hash table, each data has a unique index associated with it. If we know which index to look at, we can find the key very easily. Usually, in other programming languages, we have to use a separate hash function to calculate the hash index to store the value. The hash function is designed to generate the same index for the same key and also avoid collision. However, one of the great features of PHP is that PHP array itself is a hash table, in its underlying C implementation. Since an array is dynamic, we do not have to worry about the size of array or overflow array with many values. We need to store the values in an associative array so...

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
