I fixed some issues of the iUnTar Version 3.0 posted previously:
- Support for ././@LongLink feature that allow to store filenames more large than 100 characters
- Fixed the case that allow to unpack files with 0 length.
// PHP iUnTAR Version 3.0

function untar($tarfile,$outdir="./",$chmod=null) {
$TarSize = filesize($tarfile);
$TarSizeEnd = $TarSize - 1024;
if($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) {
$FileCHMOD = octdec("0".substr($FileMode,-3)); }

$FileCHMOD = $chmod; }
