ZipArchive - extract folder - php

Question

I am allowing users to upload portfolios in ZIP archives on my site.
The problem is that most archives have the following folder structure:
zipfile.zip
- zipfile
- file1.ext
- file2.ext
- file3.ext
is there any way to simply put the files (not the directory) onto my site (so the folder structure of their portfolio is like so)
user_name
- portfolio
- file1.ext
- file2.ext
- file3.ext
it currently uploads them like so:
user_name
- portfolio
- zipfile
- file1.ext
- file2.ext
- file3.ext
which creates all kinds of problems!
I have tried doing this:
$zip = new ZipArchive();
$zip->open($_FILES['zip']['tmp_name']);
$folder = explode('.', $_FILES['zip']['name']);
end($folder);
unset($folder[key($folder)]);
$folder = (implode('.', $folder));
$zip->extractTo($root, array($folder));
$zip->close();
to no avail.

You could do something like this:
Extract Zip file to a temp location.
Scan through it and move(copy) all the files to portfolio folder.
Delete the temp folder and its all contents (created in Step 1).
Code:
//Step 01
$zip = new ZipArchive();
$zip->open($_FILES['zip']['tmp_name']);
$zip->extractTo('temp/user');
$zip->close();
//Define directories
$userdir = "user/portfolio"; // Destination
$dir = "temp/user"; //Source
//Step 02
// Get array of all files in the temp folder, recursivly
$files = dirtoarray($dir);
// Cycle through all source files to copy them in Destination
foreach ($files as $file) {
copy($dir.$file, $userdir.$file);
}
//Step 03
//Empty the dir
recursive_directory_delete($dir);
// Functions Code follows..
//to get all the recursive paths in a array
function dirtoarray($dir, $recursive) {
$array_items = array();
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
if (is_dir($dir. "/" . $file)) {
if($recursive) {
$array_items = array_merge($array_items, dirtoarray($dir. "/" . $file, $recursive));
}
} else {
$file = $dir . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
}
}
}
closedir($handle);
}
return $array_items;
}
// Empty the dir
function recursive_directory_delete($dir)
{
// if the path has a slash at the end we remove it here
if(substr($directory,-1) == '/')
{
$directory = substr($directory,0,-1);
}
// if the path is not valid or is not a directory ...
if(!file_exists($directory) || !is_dir($directory))
{
// ... we return false and exit the function
return FALSE;
// ... if the path is not readable
}elseif(!is_readable($directory))
{
// ... we return false and exit the function
return FALSE;
// ... else if the path is readable
}else{
// we open the directory
$handle = opendir($directory);
// and scan through the items inside
while (FALSE !== ($item = readdir($handle)))
{
// if the filepointer is not the current directory
// or the parent directory
if($item != '.' && $item != '..')
{
// we build the new path to delete
$path = $directory.'/'.$item;
// if the new path is a directory
if(is_dir($path))
{
// we call this function with the new path
recursive_directory_delete($path);
// if the new path is a file
}else{
// we remove the file
unlink($path);
}
}
}
// close the directory
closedir($handle);
// return success
return TRUE;
}
}
