I’m assuming that you know binary, if you don’t, read the next chapter or learn binary somewhere else (maybe I do a tutorial) and come back here
We have covered mostly all kind of operators, we just need to take a look at bitwise operators and no more operators since next chapter ...

So, we’ve already seen Math Operators to do shit maths and Logical Operators, to choose something. Now we want to compare two things, how will we do it? With Comparations Operators (I don’t know english name so I’m sure it’s 100% wrong name).
There are 6 types of operators that can be used to compare things:

• Equal
• Not equal

Logic operators takes two booleans and returns another boolean (or takes two integers and returns one boolean, or takes two integers and returns anther integer :S)
Without talking more shit we’re going to touch logic operators right now!
And

Some times you will need to compare...

Here we are, maths, one of the things that I most hate, but why this tutorial is about math?
In programming 70% is math (the rest are syntax errors), so, if you want to code, you’ll fell in love with maths, or you will improve your logic as much as possible to don’t use maths
What are operators?...

In last tutorial we saw a general view of PHP, now we’re going to see one of the most important things in any programming language: Variables.
