Variable Question

[182x]

Hey guys,

I am about to start a project using PHP and after doing some research I have discovered that the same variable types can be implemented in different ways for example by using two different formats such as $HTTP_SESSION_VARS and $_SESSION.

So I was just wondering which format of declaring the variables is correct? And is there any major differences between the two methods?

Thanks for any help.

$HTTP_SESSION_VARS is old and not used anymore. Use $_SESSION to make sure that it will work with newer versions of PHP as well.
