Hi
Try this code to see what it is on your platform:
Brian
<?
// start with some number you are sure is an integer
// make it a really high number to lessen the execution time
$i = 2100000000;
// if you want to do it on the first try, allow it to run until finished
// it will almost certainly take more than 30 seconds
set_time_limit(0);
while(is_int($i))
{
$i++;
}
// then you have the first number that doesn't qualify as int (on your
platform)
print($i)
?>
