Fixed 2 issues:
- Support for long filenames $FileName="././@LonkLink"
- Fixed the untar of files with $FileSize=0
<?php

if($outdir!=""&&!file_exists($outdir)) {
mkdir($outdir,0777); }
$thandle = fopen($tarfile, "r");
while (ftell($thandle)<$TarSizeEnd) {
$FileName = $outdir.trim(fread($thandle,100));
$FileMode = trim(fread($thandle,8));
if($chmod===null) {

$GroupID = trim(fread($thandle,8));
$FileSize = octdec(trim(fread($thandle,12)));
