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 PHP algorithms

Now, we will check some of the built-in functionalities of PHP that solves lots of our algorithmic implementation required for day-to-day operations. We can categorize these functions into mathematics, string, cryptography and hashing, sorting, searching, and so on. We will explore the base conversion algorithms now:

  • base_convert: This function is used for base conversion of a number. The base range is restricted from 2 to 36. Since the base number can be in any base and contains characters, the first parameter for the function is string. Here is an example of the function:
$baseNumber = "123456754"; 
$newNumber = base_convert($baseNumber, 8, 16);
echo $newNumber;

  This will produce the following output:

    14e5dec
  • bin2hex: This converts a binary string to a hexadecimal string. It takes only the binary string as the parameter.
  • bindec...
