The last time we talk about control structures that choose between 1, 2 and more options, now we’re going to talk about loops.
What is a loop?

A loop is a piece of code that repeats X times, the times that the code is repeated is given by a condition, there are 2 (actually 4, I will explain 3 because I’ve never used the last one and I don’t like it) control...

Hi!!

I’m going to talk you about a linux distro based in Debian that I discovered time ago: Parrot Security OS.

What is ParrotSecurity OS?

The best answer is this: A linux for Hackers.
It has been build in top of Debian and oriented for pentesting, hacking, computer forensics, cloud pentesting, privacy and cryptography.

Why...

In the other chapters we made PHP to execute lines 1 by 1, but what about if PHP could choose what to execute? This is possible thanks to the control structures.
Control structures bassically let’s you change the flow of the code when a condition is true or false.
There are 4 control structures you can use:

• If, If…else
• Switch
• For, Foreach
• While, Do…while

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
• Less
• More
• Less or Equal
• More
