Table of contents

1.  

   Unit 1:  Foundation

   12 chapters • 3 quizzes • 8 exercises • 6 bundles

   In this unit, we'll cover all the foundational ideas of PHP including how to set up the environment to write and thereby execute PHP scripts. We'll learn about such things as variables, strings, integers, floats, data types and much more. We'll see how to write output to the terminal and retrieve input via the terminal. We'll explore functions, operations and PHP's control flow structures, in addition to the concept of variable scoping.
2.  

   Unit 2:  Numbers

   4 chapters • 3 quizzes • 2 exercises

   In this unit, we'll explore the world of numbers in PHP. We'll get to know about the internal representation of integers and floats, the exponential notation and the symbol E, how to round numbers, how to obtain random integers and much more.
3.  

   Unit 3:  Strings

   5 chapters • 2 quizzes • 4 exercises

   Strings are the cornerstone of modern-day programming. In this unit, we'll unravel all the aspects of working with strings in PHP, starting with the very basics, then moving over to concepts such as padding which is used a lot in formatting terminal output. Lastly, we'll explore string functions in PHP and then end with a final unit quiz.
4.  

   Unit 4:  Control Flow

   5 chapters • 1 quiz • 5 exercises

   Control-flow is used to refer to features of a language that affect the flow of control (execution) while running a program. In this unit, we'll cover the most common control-flow statements in PHP, starting with conditional statements: if, else, elseif, and switch, and then ending with iterative statements: for, while, and foreach.
5.  

   Unit 5:  Arrays

   6 chapters • 2 quizzes • 5 exercises

   This unit is all about one of the most useful data types in all languages — arrays. After getting a quick recap of what we learnt thus far regarding arrays in this unit, we'll be kicking into high gear. In particular, we'll explore associative arrays, array operators, common and advanced array functions, multidimensional arrays, array destructuring and unpacking, and how to sort arrays.
6.  

   Unit 6:  Functions

   3 chapters

   In this unit, we explore functions, an integral part of programming. We'll start by reviewing some basics of functions in PHP and get to know of a couple of gotchas related to functions. Next, we'll dig deeper into working with functions parameters and arguments in PHP. The unit will reach its end with a thorough discussion on closures, an intriguing concept in programming, and recursions, an ingenious idea to solve a plethora of programming problems.
