PHP zip extract and rename - php

The code below sort of works.
$zip = new ZipArchive;
if($zip->open($path) === TRUE) {
$zip->renameName('list.csv', 'list'.$batch_id.'.csv');
$zip->extractTo('list_output');
$zip->close();
}
The file inside the zip is renamed, but it does not extract. If I remove the renameName line then it extracts fine. I need it to do both.

What about?
$zip = new ZipArchive;
if($zip->open($path) === TRUE) {
$zip->extractTo('list_output');
$zip->close();
}
rename('list_output/list.csv', 'list_output/list'.$batch_id.'.csv');
Would be easier on the CPU/Memory too.

Can't unzip file with php

I have a folder in my web server were I put zip files that I need to then unzip. I want to do that with php and this is what I have tried but it does not work:
<?php
$file = $_GET["file"];
$zip = new ZipArchive;
$res = $zip->open($file+'.zip');
$zip->extractTo('./');
$zip->close();
?>
The zip files are in the same folder as the php file, but when I go to the php page it does nothing.
By doing some testing I have found out that the script dies on the $zip = new ZipArchive; line
How can I manage this to work?
<?php
$fileName = $_GET['file']; // get file name in the URL param "file"
if (isset($fileName)) { // if $fileName php variable is set than
$zip = new ZipArchive; // create object
$res = $zip->open($fileName); // open archive
if ($res === TRUE) {
$zip->extractTo('./'); // extract contents to destination directory
$zip->close(); //close the archieve
echo 'Extracted file "'.$fileName.'"';
} else {
echo 'Cannot find the file name "'.$fileName.'" (the file name should include extension (.zip, ...))';
}
}
else {
echo 'Please set file name in the "file" param';
}
?>
Note:- For More Details Please refer https://www.php.net/manual/en/class.ziparchive.php
I have found the problem.
The code is fine, but the hosting service is not, and they do not have the ZIP extension available right now
Try this code. Also change $zip->open($file+".zip"); to $zip->open($file);.
+ (plus sign) is not concatenation operator in php
<?php
// $_GET["file"] is set to `a.zip`
$file = $_GET["file"];
$zip = new ZipArchive;
$res = $zip->open($file);
$zip->extractTo('./');
$zip->close();
?>

Ziparchive extracto function treats the second parameter as folder

I tried to extract a zip file using ziparchive, here's my code:
$path = "/test/admin";
$zip = new ZipArchive;
if ($zip->open("test.zip") === TRUE) {
$zip->extractTo($path."/", array("index.php"));
$zip->close();
}
but the output becomes /test/admin/index.php/.
The file becomes a folder.
Can someone help me with this.

Trying to Use PHP's Zip Archive - Extract To Doesn't Seem to be Working

Would appreciate some help on this. I've been trying to write a PHP script that Unzips a zip file that has been created using PHP's in-built Zip Archive extension.
The zipping-up process has been very straight forward but now I'm trying to unzip this to a particular folder and it doesn't seem to be working. The only thing it does is create the folder I've asked it to extract to. No files appear in that folder.
I've had no error messages.
Thanks in Advance. Here's my code:
<?php
$root = str_replace('public_html', '', $_SERVER["DOCUMENT_ROOT"]);
$path = $root.'scripts.zip';
$zip = new ZipArchive;
$zipped = $zip->open($path, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE);
$folder = $root.'public_html/scripts/';
if ($zipped) {
$extract = $zip->extractTo($folder);
if ($extract){
echo 'Zip File Extracted';
}
$zip->close();
}
?>
I would modify your code to look like the one below.
What you were doing was creating a new zip file, not extracting the old one. ZIPARCHIVE::CREATE instructs the code to create a zip, ZIPARCHIVE::OVERWRITE tells it to overwrite existing files in the zip.
So you are not extracting anything from the zip. This code below should work
<?php
$root = str_replace('public_html', '', $_SERVER["DOCUMENT_ROOT"]);
$path = $root.'scripts.zip';
$zip = new ZipArchive;
$zipped = $zip->open($path); /*I have removed the ::CREATE & ::OVERWRITE methods*/
$folder = $root.'public_html/scripts/';
if ($zipped) {
$extract = $zip->extractTo($folder);
if ($extract){
echo 'Zip File Extracted';
}
$zip->close();
}
?>
Hope that helps

php: Is it possible to extract a zip file from a URL without writing the zip to disk?

I'm grabbing the zip file from a URL, then I copy the zip onto disk only to grab it from disk and extract it. I want to eliminate the step of having to write the zip to disk to optimize it. Here is my code...
$url_zip = 'http://returns_my_zip_file';
$new_file = '/zip_name.zip';
if (!copy($url_zip, $new_file)) { //<--- I want to eliminate this step.
echo "\n\nFailed to copy file...\n\n";
}
$zip = new ZipArchive;
if(is_readable($new_file)) {
$zip = new ZipArchive;
if ($zip->open($new_file) === TRUE) {
$zip->extractTo('ExtractToThisFolder');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
}
Thanks in advance.

PHP Zip Archive - open or extractTo is not working

I'm completely at a loss for explaining why this isn't working. HELP!
$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);
if ($res === 'TRUE') {
$unzip_success= $zip->extractTo('/temp/', "inscriptions.txt")
$zip->close();
}
the target dir "temp" is "0777" permissions
the code obtained from $res is "11" and not "TRUE" as required by the documentation on PHP.net
note: must put the full url for $archive and the first argument of extractTo
if nothing works then check if your server is linux.
if its linux you can run unzip command to unzip your file via php's system/exec function.
i.e
system("unzip archive.zip");
to extract specific file you can check man docs for unzip. many times due to server parameters zip library doesn't work as expected in that cases i switch back to linux commands.
The problem is that you are quoting TRUE, which is a keyword and should be left without single quotes. Plus, you could check if the file exists in the zip archive prior to its extraction with locateName:
$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);
if ($res === true && $zip->locateName('inscriptions.txt') !== false) {
$unzip_success= $zip->extractTo('/tmp/', "inscriptions.txt");
$zip->close();
}
ZipArcive::extractTo is case-sensitive. If file's name to be extracted do not meet zipped one exactly, the method returns false.
I faced the same problem, I have fixed this :)
Use $_SERVER['DOCUMENT_ROOT'] for url.
My code (codeigniter):
$this->load->library('unzip');
$file = $this->input->GET('file');
$this->unzip->extract($_SERVER['DOCUMENT_ROOT'].'/TRAS/application/uploads/' . $file,$_SERVER['DOCUMENT_ROOT'].'/TRAS/application/views/templates/' . $file);
If $res is equal to 11, that means that ZipArchive can't open the specified file.
To test this:
$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);
if($res == ZipArchive::ER_OPEN){
echo "Unable to open $archive\n";
}
Adding document root is what worked for me as well. here is my code
$zip = new ZipArchive;
if ($zip->open($_SERVER['DOCUMENT_ROOT'].'/'.$folder.$file_path) === TRUE) {
$zip->extractTo($_SERVER['DOCUMENT_ROOT'].'/$folder');
$zip->close();
echo 'ok';
}
I meet same problem, but I can open the zip file, it returns true after open.
My issue is I got false after $zip->extractTo().
I finally success after delete files named in CHINESE (NO-ENGILISH) in the zip file.
I had the same problem on Windows 10. The only solution I found was just to try extractTo twice, even though the open() was successful:
$zip = new ZipArchive;
if ($open === true) {
$result = $zip->extractTo($destination);
if ($result === false) {
$result = $zip->extractTo($destination);
}
$zip->close();
}
The fact that the second extractTo() works (with no intervening action) would seem to indicate that there's nothing wrong with the archive or the destination directory.
