I try to create a ZIP file with PHP. Inside this ZIP files I want to add multiple PDF files.
My code
$actual_link = "https://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$parts = parse_url($actual_link);
parse_str($parts['query'], $query);
$downloads = json_decode($query["downloads"]);
$files = array();
foreach ($downloads as $download) {
array_push($files, "https://website.com/downloads/". $download->value .".pdf");
}
# create new zip object
$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
$zip->close();
# send the file to the browser as a download
header('Content-disposition: attachment; filename="test.zip"');
header('Content-type: application/zip');
readfile($tmp_file);
unlink($tmp_file);
The ZIP file downloads fine, but my PDF files have 0kb and no content....
Do you find the error?
I'm trying to get a couple files from wordpress /uploads folder using php and I get this error:
Warning: ZipArchive::close(): Can't remove file: No such file or directory in /www/public_html/wp-content/plugins/insert-php-code-snippet/shortcode-handler.php(65) : eval()'d code on line 32 (relative to $zip->close(); and bellow "if")
I use a plugin to inject PHP on the page.
I basically have a couple dozens checkboxes that when I press "Generate", it gets the name of the file like 07/2019/blabla (with code I get uploads folder + extension, checkbox only hold the media location + name file).
I checked and it's creating the Zip on /uploads, .pdf files exist but it crashes on the close part and when I download and try to extract I get the archive is either in unknown format or damaged
Any advise please?
if(isset($_POST['files'])) {
$error = ""; //error holder
$upload_dir = wp_upload_dir();
if(isset($_POST['createzip'])){
$post = $_POST;
if(isset($post['files']) and count($post['files']) > 0){
// open zip
$zip_file = $upload_dir['basedir'].'/'.time().".zip";
$zip_name = time().".zip";
$zip = new ZipArchive();
if ($zip->open($zip_file, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE) !== TRUE) {
$error .= ("An error occurred creating your ZIP file.<br>");
}
foreach ($post['files'] as $file) {
// generate filename to add to zip
$filepath = $upload_dir['basedir'].'/' . $file . '.pdf';
if (file_exists($filepath)) {
$zip->addFile($filepath) or $error .= ("ERROR: Could not add the file $filename<br>");
} else {
$error .= ("File $filepath doesnt exit.<br>");
}
}
$zip->close();
if ($zip->close() !== true ) {
die($zip->getStatusString()."\n");
}
if(file_exists($zip_file)){
$error .= $zip_file;
ob_end_clean();
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
header("Content-Length: " . filesize($zip_file));
readfile($zip_file);
unlink($zip_file);
}
}
}
}
echo $error;
After $zip->close(); I replaced all code for this:
if(file_exists($zip_file)){
header($_SERVER['SERVER_PROTOCOL'].' 200 OK');
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: Binary");
header("Content-Length: ".filesize($zip_file));
header("Content-Disposition: attachment; filename=\"".basename($zip_file)."\"");
readfile($zip_file);
unlink($zip_file);
exit;
}
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)) {

// skip dot files while iterating

$counter = 1;
foreach ($files as $file) {
$file = realpath($file);

} else if (is_file($file)) {

}
}
} else if (is_file($source)) {
$zip->addFromString(basename($source), file_get_contents($source));

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
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;
}
I am trying to make file download script that collection all the files and download a zip file that has that collection of files not all the directory structure..
i have the file in download/folder1/folder1/filename.extension
here is my PHP codes:
if( !extension_loaded('zip') ){
echo "<script>alert('Error: Please contact to the Server Administrator!');</script>";
exit;
}
$zip = new ZipArchive;
if( $zip->open($zipname, ZipArchive::OVERWRITE) === TRUE ){
foreach( $files as $file ){
$zip->addFile( BASE_PATH.$file_path.'/'.$file, $file );
}
$zip->close();
} else {
echo "<script>alert('Error: problem to create zip file!');</script>";
exit;
}
this code gives me the structure like this:
it gives the complete path of wamp(including the path director and files) and the files, i just want to add the files not the directory..
Can someone tell me what i missed??
Every time download link comes with the unique download key, i just add the unique_key with the name of download.zip file and its working...
// $db_secret_key Random Unique Number
$zipname = $db_secret_key."_download.zip";
if( !extension_loaded('zip') ){
echo "<script>alert('Error: Please contact to the Server Administrator!');</script>";
exit;
}
$zip = new ZipArchive;
if( $zip->open($zipname, ZipArchive::CREATE) === TRUE ){
foreach( $files as $file ){
$zip->addFile( BASE_PATH.$file_path.'/'.$file, $file );
}
$zip->close();
// Force Download
header("Content-Type: application/zip");
header("Content-disposition: attachment; filename=$zipname");
header("Content-Length: ".filesize($zipname)."");
header("Pragma: no-cache");
header("Expires: 0");
readfile($zipname);
exit;
} else {
echo "<script>alert('Error: problem to create zip file!');</script>";
exit;
}
