Project Description:
You'll do a PHP website(No design needed) that should :

Have a member registration area using SQL:
-Please use PDO if you can!
-Only Nickname, age and password.
-No confirmation needed.

Every members will have a personnal page
-Let's say my member username is X :
-Then my page personal will be or

For the integrated chat :
On each users personnal page
- You'll have to echo out the age and the user's nickname on the website
- And every users will have THEIR OWN chat box (You'll see why in a few seconds)

So let's say another member's name is Y. (mine is still X):

- I want to visit Y's personnal page, I'll be able to see his informations (Age and Nickname only)
- But, unless Y send me an invitations :
* I would not see his personnal chatbox
* The output instead of the chatbox will be "Y has not invited you to his chat"
- So I will have to get an invitation from the user that I want to chat with.
- As you might have guessed, every users will be entitled to send/accept/receive/decline invitations.
- Finally, users will be able to, remove any other users of their "list of people authorized to chat with them"

NB :
- All messages should be in a database
