Intro to PHP Variables - PHP Virgin

So, do you remember x and y from algebra? I’m sure you’ve used the Quadratic formula like a million times since high school! Or how about the pythagorean theorem? A squared plus b squared equals C squared? All those x’s and y’s and a’s and b’s are variables that represent a value. PHP also lets you create variables to hold information. These variables can be numbers, like in algebra. There are two different types of numbers in PHP, integers and floats.
