Just quickly, forgot to mention:
I've tested this on 2 platforms:
Windows PHP 4.2.1
SCO Openserver 4.2.1
These two both don't work.
I just tested on SCO OpenUnix 4.2.1 - this one works!! Problem is, I need
this to work on SCO Openserver.
Thanks,
Sam

Hi,
I have a task to generate a new document number for a given range. This
document number is alphanumeric.
Here is the problem:
$lowrange1 = 90;
$highrange1 = HZ;
$currentno = 90CZZZ;
I expect that the next number in the series is: $nextnum = 90D000;
Before using this next number in the series, I need to confirm that the
number falls within the given range.
So I do something like this:
if ((strval($nextnum) = strval($lowrange1)) (strval($nextnum) =
strval($highrange1)))
{
// we have a valid number in the range
}
else
{
// not in the range
}
Now.. the problem is - PHP thinks that 90D000 is less than $lowrange1. I
individually tested them and $lowrange1 was consistently greater than the
number.
I put the strval function around each variable to ensure it was comparing
strings and not numbers for those variables that only contain numbers.
This
seems to be a problem with the letter D and E for all positions within
the 6 character alphanumeric number, except for the last position.
ie. 90D works - $lowrange1 is less than this number and $highrange1 is
greater than this number.
For all other positions where the letter D and E are generated:
ie. 9000D0, 900D00, 90D000, 9D and 9000E0, 900E00, 90E000, 9E
Is there a known problem with this? Why it is only happening with the
letters D and E? If I have 900F00 - this works, and so on for the rest
of the letters of the alphabet.
Thanks,
Sam
