how big can a scalar get?

[Vassilis Tavoultsidis]

What happens if I make a simple scalar variable big? What memory problems it
can give me and what is the limit?

e.g.

$t = "";
$maxlen = 100000;
while (length($t) < $maxlen)
{
$t = $t.$i."|";
};

It can be as big as you like. You are only limited by the size of your
computer's memory.
