If you are looking for a way to create a zip archive using PHP then you are in the right place. PHP already has the ZIP class which can help you to create and extract zip archives. It's very easy to use and all you need is the perfect guide to the PHP Zip archive.
So in this PHP tutorial you will learn how to upload multiple images and create a zip archive using PHP. you can use this script for your projects or create a zipper for the archive. We will also show you how you can open a Zip archive and display files using PHP.
Creating files Zip archive
We will use the ZipArchive class to create Zip files. So the first thing we are going to do is to instantiate the ZipArhivce class and then we use if else statement to open Zip file. Then we able to add files using the Addfile function and save the zip file using close function
<?php
//instantiate the class
$zip = new ZipArchive;
//Set Zip file name
$zip_name = "myzipfile.zip";
//files to create zip
$files ='myfile.jpg';
//Now open to create the zip file
if ($zip->open($zip_name, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE) === TRUE){
//now add the file into the zip archive
$zip->addFile($files, 'NewName.jpg');
//now save the archive using the close function
$zip->close();
} else {
echo 'failed';
}
?>
Extracting Zip files
To extract zip files we will simply add the zip file destination first and again we will open zip same as we did above, but this time we will pass the zip file destination variable and add extractTo function with the path to the folder where we want to extract files.
<?php
//instantiate the class
$zip = new ZipArchive;
//add the Zip file
$zip_file = "myzipfile.zip";
//Now open to create the zip file
if ($zip->open($zip_file) === TRUE){
//now add the file into the zip archive
$zip->extractTo('/myfolder');
//now save the archive using the close function
$zip->close();
} else {
echo 'failed';
}
?>
Display Zip Files
To list the Zip files you need to add a for loop to display Zip files, so first we open the Zip file using the open function. Then we start for loops to get files from the Zip archive then we get the details of an entry defined by its index using the Statindex function.The main php part which goes to above HTML tag
<?php //instantiate the class
$zip = new ZipArchive;
//Zip file to open
$zip_file = "myzipfile.zip";
//Now open to create the zip file
if ($zip->open($zip_file) === TRUE){
//get the Zip file names and display
for( $i = 0; $i < $zip->numFiles; $i++ ){
$stat = $zip->statIndex( $i );
print_r( basename( $stat['name'] ) . PHP_EOL );
}
} else {
echo 'failed';
}
?>
Upload Multiple images and create Zip archive
As you can see the demo of this script we have created the Zipper to create a Zip archive so when you upload images or files it will create a Zip archive and allow you to download.
We commented on every line which helps you to understand how this script works. So you can easily learn how to create zipper files using PHP.
<?php
if(isset($_POST['upload'])){
//check if files are empty
if(!empty($_FILES['files']['name'][0])){
$files = $_FILES['files'];
//Create new opject
$zip = new ZipArchive;
//create file loop for multiple files
foreach($files['name'] as $key => $filename){
$fileTmp = $files['tmp_name'][$key];
$fileSize = $files['size'][$key];
$errors = $files['error'][$key];
//get file extensions----------//
$ext = explode('.', $filename);//
$ext = strtolower(end($ext));///
//create zip file name
$zip_name = time().".zip";
//create allowed file extensions arrray
$allowed_extensions = array('txt','jpg','png','gif','svg');
//check if the file is allowed or not
if(in_array($ext, $allowed_extensions)){
//Check for errors
if($errors ===0){
//check the file sizes (2mb allowed)
if($fileSize <= 2097152){
//Generate a unique ID
$newFilesNames = uniqid('', true) . '.' . $ext;
//set file root
$root = 'uploads/' . $newFilesNames;
//move files to root
move_uploaded_file($fileTmp, $root);
//open Zip file to create archive
if($zip->open($zip_name, ZIPARCHIVE::CREATE) === TRUE){
//add files into the zip archive
$zip->addFile($root,$newFilesNames);
}
//save the archive
$zip->close();
}else{
$error = '<div class="alert alert-danger" role="alert">[$filename] is too large.</div>';
}
}
}else{
$error = '<div class="alert alert-danger" role="alert">The file "'.$filename.'" with the '.$ext.' extension is not allowed</div>';
}
}//loop end here
//check if Zip archive is created
if(file_exists($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($zip_name);
}
//Dalete uploaded the files
unlink($root);
}
}
?>
