Overview of this book

When it comes to modern web development, performance is everything. The latest version of PHP has been improvised and updated to make it easier to build for performance, improved engine execution, better memory usage, and a new and extended set of tools. If you’re a web developer, what’s not to love? This guide will show you how to make full use of PHP 7 with a range of practical projects that will not only teach you the principles, but also show you how to put them into practice. It will push and extend your skills, helping you to become a more confident and fluent PHP developer. You’ll find out how to build a social newsletter service, a simple blog with a search capability using Elasticsearch, as well as a chat application. We’ll also show you how to create a RESTful web service, a database class to manage a shopping cart on an e-commerce site and how to build an asynchronous microservice architecture. With further guidance on using reactive extensions in PHP, we’re sure that you’ll find everything you need to take full advantage of PHP 7. So dive in now!

Verifying performance improvements


The motivation for implementing the compilation to PHP was to increase the parser's performance. As a last step, we'll now try to verify that the caching layer does actually increase the performance of the parser.

For this, you can use the PHPBench package that you can install using composer:

$ composer require phpbench/phpbench

PHPBench offers a framework for benchmarking single units of code in isolation (in that respect being similar to PHPUnit, only for benchmarks instead of tests). Each benchmark is a PHP class that contains scenarios as methods. The name of each scenario method needs to start with bench.

Start by creating a bench.php file in your root directory with the following contents:

require 'vendor/autoload.php'; 
 
use Packt\Chp8\DSL\ExpressionBuilder; 
use Packt\Chp8\DSL\CompilingExpressionBuilder; 
 
class ParserBenchmark 
{ 
    public function benchSimpleExpressionWithBasicParser() 
    { 
        $builder = new ExpressionBuilder(); 
   ...
