I didn't take too much time to look at this, but I believe that where
you see:
---
sprintf("_f('%s',%d, .....
---
Try and change that to:
---
sprintf("_f('%s',%u, .....
---
>From what information you provided, it seems that this is what would
work.

Subject: PHP Directory List Script Files over 2 GB
Hello everyone
My OS information is
PHP Version 5.1.6
Apache/2.2.2 (Fedora)
Fedora Core 5 Kernel 2.6.20-1.2307.fc5
I am having some trouble with a script that displays files within a
directory.
the script does not appear to be displaying large files and the date
thaty
is displayed on these large files is Dec-31-69
I did not create the script I downloaded it from
www.celerondude.com/php-indexer
I also tried to get some assistance from the authors site but have not
been
repsonded to yet, so I thought I would try here.
The script itself is using php readdir and some javascript functions
which
is why I am so confused.
the main portions of the script is
<?php
// This block MUST be at the very top of the page!
@ob_start('ob_gzhandler');
if(isset($_GET['icon']))
{
$e=$_GET['icon'];
$I['file']='ENCODED gif files (*** I REMOVED to save SPACE ***)';
header('Cache-control: max-age=2592000');
header('Expires: '.gmdate('D, d M Y H:i:s \G\M\T',time()+2592000));
header('Content-type: image/gif');
print base64_decode(isset($I[$e])?$I[$e]:$I['file']);
exit;
}
// End block
// Start configs
$sitename='BACKUPS';
$date='M-d-y'; // date format
//
$ignore=array('.','..','.htaccess','index.php','icon.php','iconup.php','
netdirs.php','main.css','index.html','Thumbs.db'); // ignore these files
$ignore=array('.','..');
// End configs
//
$root=dirname(__FILE__);
$root="/archive1/AutoBackups";
$dir=isset($_GET['dir'])?$_GET['dir']:'';if(strstr($dir,'..'))$dir='';
$path="$root/$dir/";
$dirs=$files=array();
if(!is_dir($path)||false==($h=opendir($path)))exit('Directory does not
exist.');
while(false!==($f=readdir($h)))
{
if(in_array($f,$ignore))continue;
if(is_dir($path.$f))$dirs[]=array('name'=>$f,'date'=>filemtime($path.$f)
,'url'=>'/backupdirs1.php?dir='.rawurlencode(trim("$dir/$f",'/')));
else$files[]=array('name'=>$f,'size'=>filesize($path.$f),'date'=>filemti
me($path.$f),'url'=>trim("$root/$dir/".rawurlencode($f),'/'));
}
closedir($h);
$current_dir_name = basename($dir);
$up_dir=dirname($dir);
$up_url=($up_dir!=''&&$up_dir!='.')?'/backupdirs1.php?dir='.rawurlencode
($up_dir):'/backupdirs1.php';
// END PHP ?>
Then within the actual HTML I have the following javascript
<script type="text/javascript">

</script>
The issue I am having is that large files report 0 bytes and incorrect
values for date.
I guess the first part is for me to understand what the script is doing.
and
I have been trying to do just that
The section of code at the top that uses the readdir is what I think is
part
of the problem.
filesize only supports files less then 2 GB according to
http://us.php.net/manual/en/function.filesize.php which states
int filesize ( string $filename )
Returns the size of the file in bytes, or FALSE (and generates an
error
of level E_WARNING) in case of an error.
Note: Because PHP's integer type is signed and many platforms use
32bit
integers, filesize() may return unexpected results for files which are
larger than 2GB.
For files between 2GB and 4GB in size this can usually be overcome
by
using sprintf("%u", filesize($file)).
However due to the way the javascript function is used I am not sure how
to
correct this issue and incorporate it into what already works for the
files
less then 2 GB
function
_f(name,size,date,url,rdate){_files[_files.length]={'dir':0,'name':name,
'size':size,'date':date,'type':_ge(name),'url':url,'rdate':rdate,'icon':
'/backupdirs1.php?icon='+_ge(name)};_tsize+=size;}
Any assistance and or direction would be much appreciated appreciated
