This my code unzip file and it's working. How get the name of unzip folder name after unzip. Like zip file name is 'demo65856.zip' and unzip folder name is 'demo'.
Thanks
if(isset($_POST['submit'])){
WP_Filesystem();
$destination = wp_upload_dir();
$normal_path = $path_array;
$filename = $result->theme_file_name;
$link_filename = substr($filename, 0, -4);
$destination_path = $destination['basedir'].'/theme/';
$demo_link = $destination['baseurl'].'/theme/'.$link_filename;
$unzipfile = unzip_file( $destination_path.$filename, $destination_path);
if ( $unzipfile ) {
echo '<h3> demo link has created</h3>';
} else {
echo 'There was an error unzipping the file.';
}
}
From the manual, using ZipArchive...
<?php
$zip = new ZipArchive;
if ($zip->open($filename))
{
for($i = 0; $i < $zip->numFiles; $i++)
{
echo 'Filename: ' . $zip->getNameIndex($i) . '<br />';
}
}
else
{
echo 'Error reading zip-archive!';
}
?>
So it depends on how many files are at the base level, you may just have a base directory or a list of files. You need to try it and see what you get.

I'm creating an upload form that when uploading files will check to see if a file with the same name already exists in the directory. If a file with the same name is found, the script should increment the file by appending the file name with a number such as test1.txt test2.txt and so on until a match is not found. This is what I have come up with so far but wanted to see if there is a different approach I should take.
Also note, my filenames are already cleaned before they enter this part of the script so my filename and extension functions are simplified.
function filename($file){
return substr($file,0,strrpos($file,'.'));
}
function extension($file){
return strtolower(substr(strrchr($file,'.'),1));
}
$new_file = 'test.txt';
$dir = 'files';
$files = scandir($dir);
$exclude = array('.','..');
foreach($files as $file){
if(!in_array($file,$exclude)){
$file_array[] = $file;
}
}
$i = 1;
while(in_array($new_file,$file_array)){
$filename = filename($new_file);
$extension = extension($new_file);
if($i>1){
$num = strlen($filename);
$filename = substr($filename,0,-1);
$new_file = $filename.$i.'.'.$extension;
} else {
$new_file = $filename.$i.'.'.$extension;
}
echo $new_file.'<br>';
echo $i.'<br>';
$i++;
}
echo $new_file;
Good Day. I have a php script that move multiple file in my directory..
$filepath = 'uploads/';
if (isset($_FILES['file'])) {
$file_id = $_POST['file_id'];
$count = 0;
foreach($_FILES['file']['tmp_name'] as $k => $tmp_name){
$name = $_FILES['file']['name'][$k];
$size = $_FILES['file']['size'][$k];
if (strlen($name)) {
$extension = substr($name, strrpos($name, '.')+1);
if (in_array(strtolower($extension), $file_formats)) { // check it if it's a valid format or not
if ($size < (2048 * 1024)) { // check it if it's bigger than 2 mb or no
$filename = uniqid()."-00000-". $name;=
$tmp = $_FILES['file']['tmp_name'][$k];
if (move_uploaded_file($tmp_name, $filepath . $filename)) {
$id = $file_id;
$file_path_array = array();
$files_path = $filepath . $filename;
$file_extension = $extension;
foreach($file_name as $k_file_path => $v_file_path){
$file_path_array[] = $v_file_path;
}
foreach($file_extension as $k_file_extension){
$file_extension_array[] = $v_file_extension;
}
$file_path = json_encode($files_path);
$file_name = str_replace("\/", "/",$file_path);
var_dump($file_name);
$update = $mysqli->query("UPDATE detail SET file_path='$file_name' WHERE id='$id'");
} else {
echo "Could not move the file.";
}
} else {
echo "Your file is more than 2MB.";
}
} else {
echo "Invalid file format PLEASE CHECK YOU FILE EXTENSION.";
}
} else {
echo "Please select FILE";
}
}
exit();
}
this is my php script that move file to 'uploads/' directory and i want to save the path to my database. i try to dump the $file_name and this is my example path how to save that to my database.. ? any suggestions ?
NOTE: i already move the file to uploads/ directory and i only want to save the path to my database
string(46) "uploads/5638067602b48-00000-samplePDF.pdf"
string(46) "uploads/5638067602dee-00000-samplePDF1.pdf"
string(46) "uploads/5638067602f8d-00000-samplePDF2.pdf"
if you must store them in one field..
inside the loop
$file_name_for_db[]=$file_name;
outside the loop:
$update = $mysqli->query("UPDATE detail SET file_path='".json_encode($file_name_for_db)."' WHERE id='$id'");
there is serialize() instead of json_encode() if you prefer
The following code unzips my uploaded file and extracts everything in a directory called PDF. It then proceeds to iterate through the files and return files to download.
My problem is I need to check the file extension. I would only like to return the PDF file back to the user but some of the uploaded files have unnecessary images.
How can I check the contents of the file to ensure the unzipped file is a PDF & only the PDF is returned back to the user?
<?php
$zip = new ZipArchive;
$res = $zip->open('/download/xxxx.zip');
if ($res === TRUE) {
$zip->extractTo('/download/pdf/');
for($i = 0; $i < $zip->numFiles; $i++)
{
echo 'download';
}
$zip->close();
} else {
echo 'Something went wrong :( ';
}
?>
Thank you
Dexas solution worked for me. Here's the code if you need it
I've added in comments to show what I've changed.
<?php
$zip = new ZipArchive;
$res = $zip->open('/download/xxxxx.zip');
if ($res === TRUE) {
$zip->extractTo('/download/pdf/');
for($i = 0; $i < $zip->numFiles; $i++)
{
//Load files into variable which can be used with the following... ['dirname'], ['basename'], ['extension'], ['filename']
$path_parts = pathinfo('/download/pdf/' . $zip->getNameIndex($i));
//If the extension is equal to PDF echo the code out
if($path_parts['extension'] === 'pdf')
{
echo 'download';
}
}
$zip->close();
} else {
echo 'Something went wrong :( ';
}
?>
You can check it's MIME type using finfo
$finfo = new finfo(FILEINFO_MIME);
$type = $finfo->file('/path/to/file');
if($type === 'application/pdf')
{
//do your stuff
}
For the extension part you can use pathinfo
$ext = pathinfo('/path/to/file', PATHINFO_EXTENSION);
In the end you should check both and decide is it PDF or not.
I got this working but when i look into the zip folder all the files size is 0. I tryed not adding the files to the zip and that worked, but when i try to add them to a zip the size goes to 0. Why is this.
here is my php
if(isset($_FILES['file'])){
$file_folder = "uploads/";
$zip = new ZipArchive();
$zip_name = time().".zip";
$open = $zip->open("zip/".$zip_name, ZipArchive::CREATE);
if($open === true){
for($i = 0; $i < count($_FILES['file']['name']); $i++)
{
$filename = $_FILES['file']['name'][$i];
$tmpname = $_FILES['file']['tmp_name'][$i];
move_uploaded_file($tmpname, "uploads/".$filename);
$zip->addFile($file_folder, $filename);
}
$zip->close();
if(file_exists("zip/".$zip_name)){
// zip is in there, delete the temp files
echo "Works";
for($i = 0; $i < count($_FILES['file']['name']); $i++)
{
$filenameu = $_FILES['file']['name'][$i];
unlink("uploads/".$filenameu);
}
} else {
// zip not created, give error
echo "something went wrong, try again";
}
}
}
Your problem lies with this line: $zip->addFile($file_folder, $filename);
Currently that passes a path to the /uploads/ directory as the first argument.
According to Zip::addFile documentation you should be passing the path to the file to add (this includes the file and extension).
So change your code to include the file name (you already have it as a variable $filename which is handy).
$zip->addFile($file_folder.$filename, $filename);
I'm in need of unziping uploaded content. But for security purposes must verify the files are only image files so that somebody can't add a php into the zip and then run it later.
While doing the unzip I need to preseverve the file structure as well.
$zip->extractTo($save_path . $file_name, array('*.jpg','*.jpeg','*.png','*.gif') );
doesn't return null. Is there a parameter I can use for this or must I iterate with a loop through the zip file using regex to match extensions and create the folders and save the files with code??
Thanks
from php.net, handling .txt files
<?php
$value="test.zip";
$filename="zip_files/$value";
$zip = new ZipArchive;
if ($zip->open($filename) === true) {
echo "Generating TEXT file.";
for($i = 0; $i < $zip->numFiles; $i++) {
$entry = $zip->getNameIndex($i);
if(preg_match('#\.(txt)$#i', $entry))
{
////This copy function will move the entry to the root of "txt_files" without creating any sub-folders unlike "ZIP->EXTRACTO" function.
copy('zip://'.dirname(__FILE__).'/zip_files/'.$value.'#'.$entry, 'txt_files/'.$value.'.txt');
}
}
$zip->close();
}
else{
echo "ZIP archive failed";
}
?>
for anyone who would need this in the future here is my solution. Thanks Ciro for the post, I only had to extend yours a bit. To make sure all folders are created I loop first for the folders and then do the extarction.
$ZipFileName = dirname(__FILE__)."/test.zip";
$home_folder = dirname(__FILE__)."/unziped";
mkdir($home_folder);
$zip = new ZipArchive;
if ($zip->open($ZipFileName ) === true)
{
//make all the folders
for($i = 0; $i < $zip->numFiles; $i++)
{
$OnlyFileName = $zip->getNameIndex($i);
$FullFileName = $zip->statIndex($i);
if ($FullFileName['name'][strlen($FullFileName['name'])-1] =="/")
{
#mkdir($home_folder."/".$FullFileName['name'],0700,true);
}
}
//unzip into the folders
for($i = 0; $i < $zip->numFiles; $i++)
{
$OnlyFileName = $zip->getNameIndex($i);
$FullFileName = $zip->statIndex($i);
if (!($FullFileName['name'][strlen($FullFileName['name'])-1] =="/"))
{
if (preg_match('#\.(jpg|jpeg|gif|png)$#i', $OnlyFileName))
{
copy('zip://'. $ZipFileName .'#'. $OnlyFileName , $home_folder."/".$FullFileName['name'] );
}
}
}
$zip->close();
} else
{
echo "Error: Can't open zip file";
}
