Please can anyone help in this solution as i am new to php

$zip_name = 'path/to/final.zip'; //the real path of your final zip file on your system
$zip = new ZipArchive;
$zip->open($zip_name, ZIPARCHIVE::CREATE);
foreach($files as $file)
{
$zip->addFile($file);
}
$zip->close();
header('Content-type: application/zip');
header('Content-disposition: filename="' . $zip_name . '"');
header("Content-length: " . filesize($zip_name));
readfile($zip_name);
exit();

// This example creates a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt.
$zip = new ZipArchive;
$res = $zip->open('test.zip', ZipArchive::CREATE);
if ($res === TRUE) {
$zip->addFile('/path/to/index.txt', 'newname.txt');

//$error = ""; //error holder
//$file_path='set your image path' folder to load files
if(extension_loaded('zip'))
{ // Checking ZIP extension is available
if(count($file_names) > 0)

$zip_name = time().".zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){ // Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time<br/>";
}

Getting error when archive files ' zipArchive::close() Read Error: no such file or directory IN c:/'using PHP?

I am using PHP to download a number of files as zip folder, see code below,
it shows me this error zipArchive::close() Read error: no such file or directory in C:// path
I have added HTML button on click to take the id of the row to download its files
if (isset($_GET['zip'])) {
$zip_id = $_GET['zip'];
$query4 = "select f.id f.file_name, f.path, r.user_id from register r "
. "join files f on f.register_id =r.user_id "
. "where r.user_id=$zip_id";
$result4 = mysqli_query($con, $query4);
if (($result4)) {
while ($row = mysqli_fetch_array($result4)) {
$document[$row['id']] = array(
'id' => $row['id'],
'file_name' => $row['file_name'],
'path' => $row['path']
);
}
}
// folder to load files
if (extension_loaded('zip')) {
// Checking ZIP extension is available
foreach($document as $f){
$files[]='uploads/'.$f['path'];
}
if ($files != null) {
// Checking files are selected
$zip = new ZipArchive(); // Load zip library
$zip_name = 'folder.zip'; // Zip name
if ($zip->open($zip_name, ZIPARCHIVE::CREATE) !== TRUE) {
// Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time";
}
foreach ($files as $file){
$zip->addFile($file,$file);} // Adding files into zip
$zip->close();
if (file_exists($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 {
$error .= "* no file to zip ";
}
} else {
$error .= "* You dont have ZIP extension";
}
}
I found the error in my code. I have declared & initialized the $document array inside the while loop which is not defined for the zipArchive(). So, it cannot see it then it returns null.
the correction I have defined the creation of the $files inside the while loop.

Progress bar to prevent 504 Gateway TimeOut in ZIPARCHIVE::CREATE

I'm creating a zip with php with big files like videos. The ZIP should be around 500mb and the php crash with 504 Gateway TimeOut when i try to makeit. I want to add a progress bar or something to avoid the server saturation, i think the key is in the foreach when add files.
foreach($post['files'] as $file) {
$zip->addFile($file,basename($file));
}
i already setup max_execution_time
ini_set('max_execution_time', 0);
Any idea how is the best way?
Complete code:
<?php
set_time_limit(0);
ini_set('max_execution_time', 0);
if(isset($_POST['files']))
{ $error = ""; //error holder
{
$post = $_POST;
$file_folder = "files/"; // folder to load files
if(extension_loaded('zip'))
{
// Checking ZIP extension is available
if(isset($post['files']) and count($post['files']) > 0)
{
// Checking files are selected
$casting_titulo = $post['casting_titulo'];
$zip = new ZipArchive(); // Load zip library
$zip_name = $titulo."cast.zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)
{
// Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time";
}
foreach($post['files'] as $file) {
$zip->addFile($file,basename($file));
}
$zip->close();
if(file_exists($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);

PHP Download Multiple Files in Zip folder [duplicate]

How can I download multiple files as a zip-file using php?
You can use the ZipArchive class to create a ZIP file and stream it to the client. Something like:
$files = array('readme.txt', 'test.html', 'image.gif');
$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
$zip->addFile($file);
}
$zip->close();
and to stream it:
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);
The second line forces the browser to present a download box to the user and prompts the name filename.zip. The third line is optional but certain (mainly older) browsers have issues in certain cases without the content size being specified.
This is a working example of making ZIPs in PHP:
$zip = new ZipArchive();
$zip_name = time().".zip"; // Zip name
$zip->open($zip_name, ZipArchive::CREATE);
foreach ($files as $file) {
echo $path = "uploadpdf/".$file;
if(file_exists($path)){
$zip->addFromString(basename($path), file_get_contents($path));
}
else{
echo"file does not exist";
}
}
$zip->close();
Create a zip file, then download the file, by setting the header, read the zip contents and output the file.

You are ready to do with php zip lib,
and can use zend zip lib too,
<?PHP
// create object
$zip = new ZipArchive();
// open archive
if ($zip->open('app-0.09.zip') !== TRUE) {
die ("Could not open archive");
}
// get number of files in archive
$numFiles = $zip->numFiles;
// iterate over file list
// print details of each file
for ($x=0; $x<$numFiles; $x++) {
$file = $zip->statIndex($x);
printf("%s (%d bytes)", $file['name'], $file['size']);
print "
";
}
// close archive
$zip->close();
?>

php downloaded files in zip are empty

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;
}
