Single vs Double Quotes in PHP

Using single quotes:

My name is $name and I am $age years old.

Using double quotes:

My name is Rajko and I am 25 years old.

Explanation:

• Single quotes: Single quotes are treated as literal. Variables like $name will show up exactly how it's written in the code and special characters like \n will not be shown.
• Double quotes: Double quotes will show up and be translated as such according to the code. For example, \n will show my age and variables like $name will be show Rajko.
