Day 2: PHP Variables.

Welcome to the second day of your PHP learning journey.

Today you are going to learn about PHP variables, starting from the very beginning.

You will see how PHP variables are defined and what kind of data they can hold.

No previous coding experience is required to take these lessons.

By the end of the day, you will have a clear understanding of how PHP variables work.

If you already have some coding experience, today's lessons should be fairly simple.

If you do not have any previous coding experience, I suggest you pay particular attention to these lessons as they cover some fundamental programming concepts.

Be sure to replicate all the examples in your local development environment. It's the best way to improve faster and to remember better what you learn.

What you will learn today.

• What variables are and how they work in PHP.
• Numeric variables: integer and float numbers.
• String variables: texts and characters.
• Numeric strings: string variables that work as numbers.
