I tried two ways for adding files to ZIP. But none of them are working. Downloaded ZIP size is 0 Bytes. I have the following code to add files from uploads/Applications folder to the ZIP archive.
$zip = new ZipArchive();
$zip_name = "REU_Files.zip";
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)
die("Sorry ZIP creation failed at this time");
// first try
$handle = opendir("uploads/Applications/");
while(false !== ($file = readdir($handle)))
if ($file != "." && $file != "..")
{
$zip->addFile("uploads/Applications/" . $file);
}
// Second try
$zip->addEmptyDir("Applications/");
foreach (glob("uploads/Applications/*") as $file) {
$zip->addFile($file, "Applications/" . basename($file));
}
$zip->close();
// Making zip downloadable
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
unlink($zip_name);
Please help me finding where my code went wrong. Thanks in advance.

I am trying to create zip archive of user folder which contain files and folders. I am using WordPress and Apache server. Furthermore, I have mounted S3 bucket on the WordPress upload folder. The code is working perfectly when I try to generate zip outside mounted s3 bucket folder, and zip size is less than 10mb, but if it exceeds 10mb, zip get corrupted and 0kb file is generated. I have increase post_max_size to 1000M and memory_limit to -1, max_execution_time to 3600.
To mount s3 bucket I have used S3FS
My code:
$zip = new ZipArchive();
//$zip->open($zip_filename, ZipArchive::CREATE | ZipArchive::OVERWRITE);
if ($zip->open($zip_filename, ZipArchive::CREATE) !== true) {
exit("cannot open <$zip_filename>\n");
error_log('connot open ' . $zip_filename);
}
createZip($zip,$rootPath);
$status=$zip->getStatusString();
error_log('status: '.print_r($status, true));
$zip->close();
if (file_exists($zip_filename)) {
ob_clean();
ob_end_flush(); // more important function - (without - error corrupted zip)
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header('Content-Type: application/zip;\n');
header("Content-Transfer-Encoding: Binary");
header("Content-Disposition: attachment; filename=\"".basename($zip_filename)."\"");
header('Content-Length: ' . filesize($zip_filename));
readfile($zip_filename);
unlink($zip_filename);
}
function createZip($zip,$dir){
if (is_dir($dir)){
if ($dh = opendir($dir)){
while (($file = readdir($dh)) !== false){
// If file
if (is_file($dir.$file)) {
if($file != '' && $file != '.' && $file != '..'){
error_log('file path: '.$dir.$file);
$zip->addFile($dir.$file);
}
}else{
// If directory
if(is_dir($dir.$file) ){
if($file != '' && $file != '.' && $file != '..'){
// Add empty directory
$zip->addEmptyDir($dir.$file);
$folder = $dir.$file.'/';
// Read data of the folder
createZip($zip,$folder);
}
}
}
}
closedir($dh);
}
}
}
I'm trying to create zip file from a large folder which size almost 2GB. My code is working well on the localhost but it's not working on the server(Cpanel). In server, it's creating a zip file which size is only 103 MB out of 2GB. According to my strategy, first of all, I'm creating a backup folder recursively named "system_backup". And the backup folder is creating well without any problem. The next is, to create the zip file of 'system_backup' folder by calling the function ZipData and stored it to another folder. In this time, it's not creating the zip file properly.
After that, the function rrmdir will be called. And it will delete the 'system_backup' folder recursively. And the deletion is not working properly as well. And, in localhost, it works well.
Then, when I'm trying to download the created zip file by the function download_file, it also not download properly. It's downloaded as a broken zip file. And, in localhost, it also works well.
I have already checked the read and write permission of folders and files.
The code is given below:-
public function backup_app(){
//Backup System
ini_set('memory_limit', '-1');
set_time_limit(0);
$this->recurse_copy(FCPATH,'system_backup');
$backup_name = 'Customs-system-backup-on_'. date("Y-m-d-H-i-s") .'.zip';
$path = FCPATH.'system_backup';
$destination = FCPATH.'bdCustomsBackup/'.$backup_name;
$this->zipData($path, $destination);
//Delete directory
$this->rrmdir($path);
$message = "Application Backup on ".date("Y-m-d-H-i-s");
$this->submit_log($message);
echo 1;
}
function zipData($source, $destination) {
if (extension_loaded('zip')) {
if (file_exists($source)) {
$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE)) {
$source = realpath($source);
if (is_dir($source)) {
$iterator = new RecursiveDirectoryIterator($source);
// skip dot files while iterating
$iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::SELF_FIRST);
$counter = 1;
foreach ($files as $file) {
$file = realpath($file);
if (is_dir($file)) {
$zip->addEmptyDir(str_replace($source . '/', 'system_backup/', $file . '/'));
} else if (is_file($file)) {
$zip->addFromString(str_replace($source . '/', 'system_backup/', $file), file_get_contents($file));
}
}
} else if (is_file($source)) {
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
}
return false;
}

$this->recurse_copy($src . '/' . $file, $dst . '/' . $file);
}
else {
copy($src . '/' . $file,$dst . '/' . $file);
}
}
}
closedir($dir);
}
public function rrmdir($src) {

public function download_file($file){

$this->submit_log($message);
$path = FCPATH.'bdCustomsBackup/'.$file;
$this->load->helper('download_helper');
force_download($file, $path);
}
Here is the custom download_helper:-
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

// Grab the file extension
$x = explode('.', $filename);
$extension = end($x);

The below code is using PHP:
$zip = new ZipArchive;
if ($zip->open('test_new.zip', ZipArchive::CREATE) === TRUE)
{
// Add files to the zip file
$zip->addFile('test.txt');
$zip->addFile('test.pdf');
// Add random.txt file to zip and rename it to newfile.txt
$zip->addFile('random.txt', 'newfile.txt');
// Add a file new.txt file to zip using the text specified
$zip->addFromString('new.txt', 'text to be added to the new.txt file');
// All files are added, so close the zip file.
$zip->close();
}
Explanation of code
Line 1 creates an object of the ZipArchive class
Line 2 opens a file with filename as test_new.zip so that we can add files to it. The flag ZipArchive::CREATE specifies that we want to create a new zip file
Lines 5 & 6 are used to add files to the zip file
Line 9 is used to add a file with name random.txt to the zip file and rename it in the zipfile as newfile.txt
Line 12 is used to add a new file new.txt with contents of the file as ‘text to be added to the new.txt file’
Line 15 closes and saves the changes to the zip file
Note: Sometimes there can be issues when using relative paths for files. If there are any issues using paths then we can also use absolute paths for files
Overwrite an existing zip file
If you want to overwrite an existing zip file then we can use code similar to following. The flag ZipArchive::OVERWRITE overwrites the existing zip file.
$zip = new ZipArchive;
if ($zip->open('test_overwrite.zip', ZipArchive::OVERWRITE) === TRUE)
{
// Add file to the zip file
$zip->addFile('test.txt');
$zip->addFile('test.pdf');
// All files are added, so close the zip file.
$zip->close();
}
Explanation of code
This code will create a file test_overwrite.zip if it already exists the file will be overwritten with this new file
Create a new zip file and add files to be inside a folder
$zip = new ZipArchive;
if ($zip->open('test_folder.zip', ZipArchive::CREATE) === TRUE)
{
// Add files to the zip file inside demo_folder
$zip->addFile('text.txt', 'demo_folder/test.txt');
$zip->addFile('test.pdf', 'demo_folder/test.pdf');
// Add random.txt file to zip and rename it to newfile.txt and store in demo_folder
$zip->addFile('random.txt', 'demo_folder/newfile.txt');
// Add a file demo_folder/new.txt file to zip using the text specified
$zip->addFromString('demo_folder/new.txt', 'text to be added to the new.txt file');
// All files are added, so close the zip file.
$zip->close();
}
Explanation of code
The above code will add different files inside the zip file to be inside a folder demo_folder
The 2nd parameter to addfile function can be used to store the file in a new folder
The 1st parameter in the addFromString function can be used to store the file in a new folder
Create a new zip file and move the files to be in different folders
$zip = new ZipArchive;
if ($zip->open('test_folder_change.zip', ZipArchive::CREATE) === TRUE)
{
// Add files to the zip file
$zip->addFile('text.txt', 'demo_folder/test.txt');
$zip->addFile('test.pdf', 'demo_folder1/test.pdf');
// All files are added, so close the zip file.
$zip->close();
}
Explanation of code
We store the file test.txt into demo_folder and test.pdf into demo_folder1
Create a zip file with all files from a directory
$zip = new ZipArchive;
if ($zip->open('test_dir.zip', ZipArchive::OVERWRITE) === TRUE)
{
if ($handle = opendir('demo_folder'))
{
// Add all files inside the directory
while (false !== ($entry = readdir($handle)))
{
if ($entry != "." && $entry != ".." && !is_dir('demo_folder/' . $entry))
{
$zip->addFile('demo_folder/' . $entry);
}
}
closedir($handle);
}
$zip->close();
}
Explanation of code
Lines 5-16 opens a directory and creates a zip file with all files within that directory
Line 5 opens the directory
Line 7 gets the name of each file in the dir
Line 9 skips the “.” and “..” and any other directories
Line 11 adds the file into the zip file
Line 14 closes the directory
Line 17 closes the zip file
I'm using this code to have users download all files in a given directory:
<?php
set_time_limit();
$zipname = getcwd();
$zipname = substr($zipname,strrpos($zipname,'/')+1);
$zipname = $zipname.'.zip';
$zip = new ZipArchive;
$zip->open('./'.basename($zipname).'', ZipArchive::CREATE);
if ($dir_handle = opendir('./')) {
while (false !== ($entry = readdir($dir_handle))) {
if ($entry != "." && $entry != ".." && !strstr($entry,'.php')) {
$zip->addFile($entry);
}
}
closedir($dir_handle);
}
else {
die('file not found');
}
$zip->close();
header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename="'.basename($zipname).'"');
header('Content-Length: ' . filesize($zipname));
header('Location: ./'.$zipname);
?>
The code works perfectly, but I wanted to delete from the server after the user downloads it, so I tried by just adding
unlink($zipname);
in the last line. Obviously I got a File not found error.
Then I tried replacing the last header with
readfile($zipname);
and the download starts, but the zip file downloaded is somehow corrupted and will not unzip.
What am I doing wrong?
Thanks for your help
That's because $zipname is just .zip after your substr call.
example:
https://3v4l.org/7L515
Do this instead:
$zipname = dirname(__FILE__).".zip";
also, this sounds like a bad idea to begin with.
I'm very new to php and I just made my first script, which is working fine, but is missing a final touch.
The script zips all files in the folder containing the php and creates a downloadable archive.
Here's the code
<?php
$zipname = 'test.zip';
$zip = new ZipArchive;
$zip->open('D://mypath//zip//$zipname', ZipArchive::CREATE);
if ($dir_handle = opendir('./')) {
while (false !== ($entry = readdir($dir_handle))) {
if ($entry != "." && $entry != ".." && !strstr($entry,'.php') && !strstr($entry,'.zip')) {
$zip->addFile($entry);
}
}
closedir($dir_handle);
}
else {
die('file not found');
}
$zip->close();
header('Content-Type: application/zip');
header("Content-Disposition: attachment; filename=$zipname");
header('Content-Length: ' . filesize($zipname));
header("Location: $zipname");
?>
What I'd like to achieve is having $zipname = "the name of the folder.zip"
So, if the php is inside "/mypath/blablabla/" i want my zip $zipname to be "blablabla.zip"
Any help will be appreciated!
EDIT:
here's the working code:
<?php
$zipname = getcwd();
$zipname = substr($zipname,strrpos($zipname,'\\')+1);
$zipname = $zipname.'.zip';
$zip = new ZipArchive;
$zip->open('D:/inetpub/webs/mydomaincom/zip/'.basename($zipname).'', ZipArchive::CREATE);
if ($dir_handle = opendir('./')) {
while (false !== ($entry = readdir($dir_handle))) {
if ($entry != "." && $entry != ".." && !strstr($entry,'.php')) {
$zip->addFile($entry);
}
}
closedir($dir_handle);
}
else {
die('file not found');
}
$zip->close();
header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename="'.basename($zipname).'"');
header('Content-Length: ' . filesize($zipname));
header('Location: /zip/'.$zipname);
?>
You could use getcwd() :
http://php.net/manual/fr/function.getcwd.php
$zipname = getcwd();
It'll return the path of the current folder, then you could just hash the result to get only the name of the folder :
// We remove all the uneeded part of the path
$zipname = substr($zipname,strrpos($zipname,'\\')+1);
//Then we add .zip to the result :
$zipname = $zipname.'.zip';
This should do the trick.
And if you want to also use the name of the parent folder :
$zipname = getcwd();
// We remove the uneeded part of the path
$parentFolderPath = substr($zipname, 0,strrpos($zipname,'\\'));
$parentFolder = substr($parentFolderPath, strrpos($parentFolderPath,'\\')+1);
//Keep current folder name
$currentFolder = substr($zipname,strrpos($zipname,'\\')+1);
//Join both
$zipname = $parentFolder.'_'.$currentFolder;
//Then we add .zip to the result :
$zipname = $zipname.'.zip';
Instead of redirecting with header(), you could use readfile():
header('Content-Disposition: attachment; filename="'.basename($zipname).'"');
readfile($zipname);
With basename() only the last part is shown to the user and with readfile() you are giving out the actual file, no matter where it is.
currently I am trying to put files in a zip and download them. I use the following code:
# create new zip opbject
$zip = new ZipArchive();
# create a temp file & open it
$tmp_file = tempnam('.','');
$zip->open($tmp_file, ZipArchive::CREATE);
# loop through each file
foreach($files as $file){
# download file
$download_file = file_get_contents($file);
#add it to the zip
$zip->addFromString(basename($file),$download_file);
}
# close zip
$zip->close();
# send the file to the browser as a download
header('Content-disposition: attachment; filename=Resumes.zip');
header('Content-type: application/zip');
readfile($tmp_file);
The files are added to the array the following way:
$weborder = $_POST['weborder'];
$printlocation = $_POST['print'];
$dir = "z:\Backup\\$printlocation\\$weborder.zip";
$zip = new ZipArchive;
$files = array();
if ($zip->open($dir))
{
for($i = 0; $i < $zip->numFiles; $i++)
{
if ($zip->getNameIndex($i) != "order-info.txt" && $zip->getNameIndex($i) != "workrequest.xml" && $zip->getNameIndex($i) != "workrequest.pdf")
{
$filename = $zip->getNameIndex($i);
$files[$i] = $dir . "\\" . $filename;
}
}
}
This downloads the zip and the files that are in the zip. The only problem I am having is that the files are empty.
instead of
$zip->addFromString(basename($file),$download_file);
try
$zip->addFile($basename($file));
This code is working make sure that your files are existed or not.
$array = array("sites/README.txt","sites/chessboard.jpg"); //files to Add/Create in zip file
$zip = new ZipArchive(); // Load zip library
$zip_name = time().".zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)
{
// Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time";
}
foreach($array as $key => $value)
{
if(file_exists($value)){
$zip->addFile($value); // Adding files into zip
}else{echo $value ." file not exist<br/>";}
}
$zip->close();
if(file_exists($zip_name))
{
echo "yes";die;
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
}else{echo "zip not created";die; }
For Download Existing file
$zip_name = "YOUR_ZIP_FILE PATH";
if(file_exists($zip_name))
{
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
//unlink($zip_name);
}else{
echo "zip not created";exit;
}
