Cannot rename temp file to save on saveAsFile

[htcrkrishnamoorthy]

Just using below lines to add another file to existing ZIP

$destination = "C:/wamp64/www/oc3/test.zip";
$zipFile = new \PhpZip\ZipFile();
$zipFile->openFile($destination);
$retValue = $zipFile->addFile("backup.log");
$zipFile->saveAsFile($destination);
$retValue = $zipFile->close();

When it comes saveAsFile. it gives access denied error by rename() function on line 1614 of ZipFile.php where you are trying to rename temp file to ZIP. The folder has full access permission. May be because the $destination is still open in the memory and it is not able to move the file.

If I am creating a brand new zip file and use saveAsFile, it is working fine

Hello. Test your code with a modified version

composer require nelexa/zip:dev-feature/overwrite

[htcrkrishnamoorthy]

Don't see any difference. Still see the same error

What is the result of this code?

<?php

var_dump(is_writable('C:/wamp64/www/oc3/test.zip'));

Since this is Windows, use backslashes in the file name.

$destination = 'C:\wamp64\www\oc3\test.zip';
$zipFile = new \PhpZip\ZipFile();
$zipFile
    ->openFile($destination)
    ->addFile('backup.log')
    ->rewrite() // or ->saveAsFile($destination)
    ->close()
;

var_dump(is_writable('C:/wamp64/www/oc3/test.zip')); was added before calling rename() in saveAsFile function in ZipFile.php

It returns true

C:\wamp64\storage\vendor\nelexa\zip\src\ZipFile.php:1613:boolean true

Changed code to use rewrite() instead of saveAsFile. Still the error is same

Removed @ before rename() function to get the exact error and is below Warning: rename(C:\wamp64\www\oc3\test.zip.temp5eb0d6d4945a18.96620773,C:\wamp64\www\oc3\test.zip): Access is denied. (code: 5) in C:\wamp64\storage\vendor\nelexa\zip\src\ZipFile.php on line 1614

This seems like a server setup problem, not a library problem. Try to execute this code in php-cli mode.

What does the file C:\wamp64\www\oc3\test.zip contain? Are you sure you want to update it, and not save the file to another path?

Hi guys, I haved the same problem and this moment I fixed it like this: ` public function saveAsFile($filename) { $filename = (string) $filename;

    $tempFilename = $filename . '.temp' . uniqid('', true);

    if (!($handle = @fopen($tempFilename, 'w+b'))) {
        throw new InvalidArgumentException('File ' . $tempFilename . ' can not open from write.');
    }
    $this->saveAsStream($handle);

    sleep(2);

    if (!@rename($tempFilename, $filename)) {
        if (is_file($tempFilename)) {
            unlink($tempFilename);
        }

        throw new ZipException('Can not move ' . $tempFilename . ' to ' . $filename);
    }

    return $this;
}`

I dont know if is a good solution but that fix the problm. tell me il there is another solution.

Thank you @ckwsoft . I don't think this is a environment related issue. This was happening on other servers as well. The saveAsStream seems to have the file handle still open even if it is exclusively closing it. I will try your solution.
