Course Introduction:In this PHP course, you'll learn how to install PHP on Windows, choose a suitable text editor, and set it up. You'll start by writing HTML, learning about the use of variables and different data types. Then, you'll learn how to handle strings, numbers, and get user input. Next, you'll use these basics to build a basic calculator and a Mad Libs game. Before continuing, you will learn how to handle URL parameters and pass data using the POST and GET methods. Arrays are an important concept for storing and processing data in PHP, and you'll learn how to use checkboxes and associative arrays. In the Functions section, you will learn how to define and use functions, and how to use return statements. In Conditional Statements, you'll explore the context of if statements and learn how to build a better calculator. Switch statement will help you execute different code blocks based on different conditions. Loops are important programming concepts, and you'll learn the use of while and for loops. You'll also learn how to add comments and learn how to include PHP code in HTML. Before going further, you will learn how to include PHP files in HTML files using the include function. Classes and objects are at the heart of object-oriented programming, and you'll learn how to define classes, constructors, and object functions. Finally, you'll learn how to use getters and setters to access and modify an object's properties. By completing this course, you will build

Course Introduction:Benchmarking provides insight into PHP function performance: identifying functions that need testing. Set up a baseline use case and define the function inputs and execution times to be tested. Use benchmarking tools such as PhpBench to test and collect performance metrics. Compare results and identify performance differences. Based on benchmark results, apply optimization techniques to improve performance. The practical case shows how to use PhpBench to benchmark array processing functions to determine the execution time of different functions, thereby providing a basis for code optimization.
