Learn the fundamentals of PHP from structural programming to object-oriented techniques.

Web Development with PHP

This highly interactive module introduces us to fundamental programming concepts in PHP—one of the most popular languages in the world. It begins with a simple “Hello, World!” program and proceeds to cover common concepts such as conditional statements, loop statements, and logic in PHP. It then reflects upon the idea of functions and arrays, as well as the power they give to the programmer to write better code.

Finally, it dives deeper into advanced concepts such as classes, inheritance, and exception handling in PHP. By the time we're done, we’ll have a good grip on the basics of PHP and will be ready to study advanced concepts.

Learn PHP from Scratch

PHP allows us to pass *arguments* into a *function* in **two** ways:

* **Pass by Value**
* **Pass by Reference** 

Let's take a look at **pass by value** *method*.

## Arguments Passed by Value 
On passing *arguments* using **pass by value**, the value of the argument gets changed within a *function*, but the **original** value outside the *function* remains **unchanged**. That means a **duplicate** of the *original* value is passed as an *argument*.

## Example: Cube of a Number
Consider the following program that accepts a *number* and prints its **cube**:
