Bug description: unpack returns strange values
Description:
------------
Hi,
I have a really strange behaviour with unpack() function and i didn't
found any bug / issue like this one.
The result of unpack() is diff. on a spcific server (my client's new
hosting company).
I tested the script on Win and Linux and everything works fine, with the
same .dbf file (the file is not corrupted).
Please help.
Many thanks,
Radu
Reproduce code:
---------------
$data = fread ($fp, 32) or die ("Could not read data from file
<i>$file</i>");
$header_format = 'H2id/' . 'CYear/' . 'CMonth/' . 'CDay/' . 'L# of
Records/' . 'SHeader Size/' . 'SRecord Size';
$header = unpack ($header_format, $data);
Expected result:
----------------
Array ( [id] => 03 [Year] => 105 [Month] => 7 [Day] => 2 [# of Records] =>
2713 [Header Size] => 129 [Record Size] => 58 )
Actual result:
--------------
Array ( [id] => 03 [Year] => 105 [Month] => 7 [Day] => 2 [# of Records] =>
2713 [Header Size] => 33024 [Record Size] => 14848 )
