Increase the value of a variable by one each time

[janhouse00]

Hi, is there any way to increase the value of a variable,$test(in a function) by one each time the script is called?
<? //test.php

function main(){
print"The value of variable a will auto increment by 1: $test";
}

main();

?>

I don't use cookie since the users maybe turn it off. Thanks in advance.

Use a session variable stored in a file which avoids cookies?

$_SESSION[count]++;

Using cookies is a best course of action, because most times they will have cookies turned on.

Plus, what if a university has a border box -- proxy -- ip masquerading router -- whatever you choose to call it -- and the requests of two+ users come from the same IP.

What then?
