I kind of get isset function, but not entirely.
I understand it is mainly used with if statements.
Is it just for submitting forms? And what is the difference for isset with GET and POST?
If I use it for GET
Does this check the url to see if there is a value for page?
And for POST, does it just mean, if the form submit button is clicked?
