PHP integers are 32 bit.
The actual value of $o is not what you think it is... Do this:
var_dump($o);

Description:
------------
I was testing long strings of numbers against an IF statement (see test)
script and it was outputting information which was not true.

Test script:
---------------
This works:

$o = 33;
if ($o >= 29 && $o <= 32)
{
    echo "true";
} else {
    echo "false";
}

This does not work:

$o = 336571324099282374385465584513479344133;
if ($o >= 336571324099282374385465584513479344129 && $o <=
336571324099282374385465584513479344132)
{
    echo "true";
} else {
    echo "false";
}

Expected result:
----------------
In the working example, the output should be false. This is working as
expected.

In the non-working example, the output should be false. However, it is
returning true.
