Extract ZIP file, including hidden files - php

Question

I'm using ZipArchive and I want to extract ZIP file.
I can see a comment in the docs for ZipArchive::extractTo:
Note, in Linux (possibly other *nix platforms too) there is no way to extract hidden files ( aka filename starting with a '.') from a Zip archive.
And very important note: I need it to work on both *nix and Windows platforms.
So how to properly extract ZIP file into dir, including hidden files?
Thanks in advance,
JK.

Answer 1

You could use the system() or exec() functions if the server allows them :
system("unzip archive.zip");
There are although shell_exec() and passthru().
Hope it helps.
EDIT
Since OP looking for pure-php solution here is a user implemented function for php manual (Zip Functions) :
<?php
/**
* Unzip the source_file in the destination dir
*
* #param string The path to the ZIP-file.
* #param string The path where the zipfile should be unpacked, if false the directory of the zip-file is used
* #param boolean Indicates if the files will be unpacked in a directory with the name of the zip-file (true) or not (false) (only if the destination directory is set to false!)
* #param boolean Overwrite existing files (true) or not (false)
*
* #return boolean Succesful or not
*/
function unzip($src_file, $dest_dir=false, $create_zip_name_dir=true, $overwrite=true)
{
if ($zip = zip_open($src_file))
{
if ($zip)
{
$splitter = ($create_zip_name_dir === true) ? "." : "/";
if ($dest_dir === false) $dest_dir = substr($src_file, 0, strrpos($src_file, $splitter))."/";
// Create the directories to the destination dir if they don't already exist
create_dirs($dest_dir);
// For every file in the zip-packet
while ($zip_entry = zip_read($zip))
{
// Now we're going to create the directories in the destination directories
// If the file is not in the root dir
$pos_last_slash = strrpos(zip_entry_name($zip_entry), "/");
if ($pos_last_slash !== false)
{
// Create the directory where the zip-entry should be saved (with a "/" at the end)
create_dirs($dest_dir.substr(zip_entry_name($zip_entry), 0, $pos_last_slash+1));
}
// Open the entry
if (zip_entry_open($zip,$zip_entry,"r"))
{
// The name of the file to save on the disk
$file_name = $dest_dir.zip_entry_name($zip_entry);
// Check if the files should be overwritten or not
if ($overwrite === true || $overwrite === false && !is_file($file_name))
{
// Get the content of the zip entry
$fstream = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
file_put_contents($file_name, $fstream );
// Set the rights
chmod($file_name, 0777);
echo "save: ".$file_name."<br />";
}
// Close the entry
zip_entry_close($zip_entry);
}
}
// Close the zip-file
zip_close($zip);
}
}

{
return false;
}
return true;
