$_POST, $_GET and Passing Variables

[BeastRider]

OK... call me thick... it won't be the first time.

a) as an academic exercise, what is the difference between $POST and $GET?

b) I know that I can pass URL's from script to script via the URL as in

myscript.php?var1=1&var2=3

but can I pass a variable that is not the result of user input on a form? For example, if I declare

$aarkvark = "anteater";

in one script can I pass this variable to another script without using the URL? If so, how?

Thank you.

like the name says $_POST is when the data is submitted through a form using method="POST", you will not see the variables displayed in the browser URL window. and when u pass variables in a form using method="GET" or like myscript.php?var1=1&var2=3 then its GET

in one script can I pass this variable to another script without using the URL? If so, how?

u could use sessions or cookies to pass the variable from one page to another with using the URL
