The following lines are causing the above error report:
[Variable names are changed for a better overview)
> Original:
if ($tcompressed) { $direct_tempdata_1string = gzinflate (@fread
($zipp,$tlength)); }
else { $direct_tempdata_1string = @fread ($zipp,$tlength); }
> Possible fix (unsuccessful):
if ($tcompressed)
{
$direct_tempdata_1string = "";
$direct_tempdata_2string = 0;
do
{
if (($tlength - $direct_tempdata_2string) > 999) {
$direct_tempdata_3string = 1000; }
else { $direct_tempdata_3string = ($tlength -
$direct_tempdata_2string); }
$direct_tempdata_2string += $direct_tempdata_3string;
$direct_tempdata_1string .= gzinflate (@fread
($zipp,$direct_tempdata_2string));
}
while ($direct_tempdata_2string < $tlength);
}
else { $direct_tempdata_1string = @fread ($zipp,$tlength); }
> Var-Details:
$direct_tempdata_1string = Result string (uncompressed data from a zip
archive)
$direct_tempdata_2string = Bytes already read from the archive
$direct_tempdata_3string = Next byte length to read
I tried to reduce the $direct_tempdata_3string down to 100 byte for
inflating but still getting the buffer error (2) seen in the report
above.
