Hi everybody -
What is wrong with this php zip class (file : phpzip.inc.php)?
I've got this code on one page:
require("phpzip.inc.php");
$z = new PHPZip();
$z -> Zip("directory_name/", "out.zip");
where all files and sub-directories + files should be zipped into the zip
file called out.zip
trouble is the class does zip the files in the "directory_name" directory
but does not include the subdirectories and their files.
Works on Windows server but not on unix server
Thanks!
this is the class:
GetFileList($dir);
}
if ((!empty($dir))&&(!is_array($dir))&&(file_exists($dir))) chdir($dir);
else chdir($curdir);
if (count($filelist)>0)
{
foreach($filelist as $filename)
{
if (is_file($filename))
{
$fd = fopen ($filename, "r");
$content = fread ($fd, filesize ($filename));
fclose ($fd);
if (is_array($dir)) $filename = basename($filename);
$this -> addFile($content, $filename);
}
}
$out = $this -> file();
chdir($curdir);
$fp = fopen($zipfilename, "w");
fwrite($fp, $out, strlen($out));
fclose($fp);
}
return 1;
}
else return 0;
}

{

chdir($dir.$files);
$file = array_merge($file, $this -> GetFileList("", "$pref$files/"));

}
else $file[]=$pref.$files;
}
}
closedir($dh);
}
return $file;
