Extract sub folders of ZIP file in PHP - php

Question

I am using a php script to unzip ZIP file. but this script unzip only one level of directories without extracting the sub directories of that file
the script:
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
$zip->extractTo('/my/destination/dir/');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
for example: if the test.zip contains 2 folders: folder1\file.png, folder2\folder3\file3.png
after extracting this ZIP file, i only see the folder1*.* and folder2*.* but without the sub directory folder3.
How can i improve it?

I think this PHP manual will be helpful to you
http://php.net/manual/en/ref.zip.php
<?php
$file = "2537c61ef7f47fc3ae919da08bcc1911.zip";
$dir = getcwd();
function Unzip($dir, $file, $destiny="")
{
$dir .= DIRECTORY_SEPARATOR;
$path_file = $dir . $file;
$zip = zip_open($path_file);
$_tmp = array();
$count=0;
if ($zip)
{
while ($zip_entry = zip_read($zip))
{
$_tmp[$count]["filename"] = zip_entry_name($zip_entry);
$_tmp[$count]["stored_filename"] = zip_entry_name($zip_entry);
$_tmp[$count]["size"] = zip_entry_filesize($zip_entry);
$_tmp[$count]["compressed_size"] = zip_entry_compressedsize($zip_entry);
$_tmp[$count]["mtime"] = "";
$_tmp[$count]["comment"] = "";
$_tmp[$count]["folder"] = dirname(zip_entry_name($zip_entry));
$_tmp[$count]["index"] = $count;
$_tmp[$count]["status"] = "ok";
$_tmp[$count]["method"] = zip_entry_compressionmethod($zip_entry);
if (zip_entry_open($zip, $zip_entry, "r"))
{
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
if($destiny)
{
$path_file = str_replace("/",DIRECTORY_SEPARATOR, $destiny . zip_entry_name($zip_entry));
}
else
{
$path_file = str_replace("/",DIRECTORY_SEPARATOR, $dir . zip_entry_name($zip_entry));
}
$new_dir = dirname($path_file);
// Create Recursive Directory (if not exist)
if (!file_exists($new_dir)) {
mkdir($new_dir, 0700);
}
$fp = fopen($dir . zip_entry_name($zip_entry), "w");
fwrite($fp, $buf);
fclose($fp);
zip_entry_close($zip_entry);
}
echo "\n</pre>";
$count++;
}
zip_close($zip);
}
}
Unzip($dir,$file);
?>

This script extracts all files in the zip file recursively. This will extract them into the current directory.
<?php
set_time_limit(0);
echo "HI<br><br>";
//----------------
//UNZIP a zip file
//----------------
$zipfilename = "site.zip";
//----------------
function unzip($file){
$zip=zip_open(realpath(".")."/".$file);
if(!$zip) {return("Unable to proccess file '{$file}'");}
$e='';
while($zip_entry=zip_read($zip)) {
$zdir=dirname(zip_entry_name($zip_entry));
$zname=zip_entry_name($zip_entry);
if(!zip_entry_open($zip,$zip_entry,"r")) {$e.="Unable to proccess file '{$zname}'";continue;}
if(!is_dir($zdir)) mkdirr($zdir,0777);
#print "{$zdir} | {$zname} \n";
$zip_fs=zip_entry_filesize($zip_entry);
if(empty($zip_fs)) continue;
$zz=zip_entry_read($zip_entry,$zip_fs);
$z=fopen($zname,"w");
fwrite($z,$zz);
fclose($z);
zip_entry_close($zip_entry);
}
zip_close($zip);
return($e);
}
function mkdirr($pn,$mode=null) {
if(is_dir($pn)||empty($pn)) return true;
$pn=str_replace(array('/', ''),DIRECTORY_SEPARATOR,$pn);
if(is_file($pn)) {trigger_error('mkdirr() File exists', E_USER_WARNING);return false;}
$next_pathname=substr($pn,0,strrpos($pn,DIRECTORY_SEPARATOR));
if(mkdirr($next_pathname,$mode)) {if(!file_exists($pn)) {return mkdir($pn,$mode);} }
return false;
}
unzip($zipfilename);
?>

Try this simple way:
system('unzip my_zip_file.zip');
