[RESOLVED] Compress Dir's

mark_kccs

Hi to all

I am trying to compress a few dir's each having sub-dir's and so on. I have found a script that works for the most part but has an issue with larger dir's. The script is as follows;

$zipfile = 'C:\test\bk_'.date('d_m_Y_H_i_s');

$folders=array('C:\1','C:\2','C:\3','C:\4');

$filenames = array();

function browse($dir) {
global $filenames;
    if ($handle = opendir($dir)) {
        while (false !== ($file = readdir($handle))) {
            if ($file != "." && $file != ".." && is_file($dir.'/'.$file)) {
                $filenames[] = $dir.'/'.$file;
            }
            else if ($file != "." && $file != ".." && is_dir($dir.'/'.$file)) {
                browse($dir.'/'.$file);
            }
        }
        closedir($handle);
    }
    return $filenames;
}

foreach($folders as $key =>$directory){
browse($directory);

$zip = new ZipArchive();

if ($zip->open($zipfile.'_'.$key.'.zip', ZIPARCHIVE::CREATE)!==TRUE) {
    exit("cannot open zipfile");
}

foreach ($filenames as $filename) {
    $zip->addFile($filename,$filename);
}
$filenames = array();
echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();
}

The output is;
numfiles: 335
status:0
numfiles: 155
status:0
numfiles: 509
status:11
numfiles: 509
status:11

The files are structured;
1 13.7 mb with 335 files
2 16.6 mb with 155 files
3 53.7 mb with 2187 files
4 55.5 mb with 4611 files

So dir 3 and 4 are not written.

I would welcome any suggestions as to achieving this goal either with this script or something akin.

Many thanks

mark_kccs,

The issue according to http://pecl.php.net/bugs/bug.php?id=8714 seems to be a file handle limit with Windows XP Home. (~ 509 Handles / Files)

If you are running Windows XP Home the recommendation is to stop at 500 files, close the archive, and reopen it, and repeat for up to 500 files.

Here is a quote from the link that I had provided outlining the issue and potential solution:

OK, another explanation, you reached the file handles limit.

1 handle the php script
1 handle the zip archive
1 handle the extension
509 handles (509 tmp files for the entries)
512 handles

I think it is the limit of windows XP Home. I use XP Pro 64bit and
Server 2003 without troubles (same for XP Pro X86).

What I suggest is to close the archive at 500~ and reopen it. It will
close the handles while closing the archive.

I thank you for the detailed info. However I cannot provide a fix, this
is a Win XP Home "limitation". Future versions of php may have a work
around, but now warranty.

Hi big.nerd

Thanks for the reply.

This script is running on a win2003 sbs so not sure if this limit applies here. Do you know of any other way to zip a large dir?

Many thanks.

hi big.nerd

The work around of closing and opening has done the trick.

Many thanks for the solution.
