PHP - Zip A Directory

ironclaw · 07-09-2011 12:47PM #1

Hi Folks,

I'm looking for a way to ZIP an entire directory using PHP. I won't know whats in the directory before I ZIP it.

Here's my code so far but I get a empty folder when downloaded.

Any help appreciated!

$archive_name = "archive.zip"; // name of zip file
$archive_folder = "uploads"; // the folder I want to archive

$zip = new ZipArchive;
if ($zip -> open($archive_name, ZipArchive::CREATE) === TRUE)
{
    $dir = preg_replace('/[\/]{2,}/', '/', $archive_folder."/");
   
    $dirs = array($dir);
    while (count($dirs))
    {
        $dir = current($dirs);
        $zip -> addEmptyDir($dir);
       
        $dh = opendir($dir);
        while($file = readdir($dh))
        {
            if ($file != '.' && $file != '..')
            {
                if (is_file($file))
                    $zip -> addFile($dir.$file, $dir.$file);
                elseif (is_dir($file))
                    $dirs[] = $dir.$file."/";
            }
        }
        closedir($dh);
        array_shift($dirs);
    }
   
    $zip -> close();
    echo 'Archive Done!';
}
else
{
    echo 'Error, can\'t create a zip file!';
}

Have you tried a very basic example (e.g. Example 2 on the ZipArchive::open page) ?

Maybe hard code a few filenames into the code to verify that the basics are working before using opendir/readdir data.
