MySQL and Variables?

Is it possiable to put a variable line in a database like : $username that calls information from the database itself and shows it in a script?

What exactly do you mean?

i store this variable into a database
$username

if I have it slected to show

it will be put into a script I have made for it.

then the variable will call the information that it has stored in the database which would be the users, username... possiable?

I still don't understand.

You can insert the content of a variable in the database, not the variable itself.

You can read the data from the variable out of the database and put it into a variable again to print it.

Ohh ok. I got it. thanks.
