Regarding the problem (posted by Dan) of checking for a zero where the zero is at the end of a
string, the following will work. Note that !== is used rather than != which doesn't work.
$total = "Your total is 0";
$srchstrng = "0";
if (stristr($total, $srchstrng) !== FALSE)
{
echo "you have nothing";
}
This will correctly output "you have nothing", indicating the zero was correctly
identified as being in the $total string.
