Sounds like a file permissions issue. Make sure the owner and permissions are correct.

Please show your PHP code that caused the error.

private function extractDataFromZip(StreamInterface $bodyResponse) { try { $this->zipFile->openFromString($bodyResponse);

        if (!$this->zipFile->valid()) {
            return;
        }

        $this->zipFile->extractTo(self::UNZIP_DIR);

        $listFiles = $this->zipFile->getListFiles();

        $tempDir = stristr($listFiles[0], '/', true);

        $this->zipFile->close();

        foreach ($listFiles as $gzipFile) {
            yield gzfile(self::UNZIP_DIR . $gzipFile);

            unlink(self::UNZIP_DIR . $gzipFile);
        }

        exec("rm -rf " . self::UNZIP_DIR . $tempDir);
    } catch (Exception $exception) {
        $this->zipFile->close();
        throw $exception;
    }
}

1. $this->zipFile->valid() The valid method is not for validation, but for iteration.
2. $this->zipFile->extractTo(self::UNZIP_DIR); the method can return a list of extracted files:

        $zipFile->extractTo(self::UNZIP_DIR, null, [], $extractedEntries);
        $zipFile->close();

        foreach ($extractedEntries as $fileName => $zipEntry){
            yield gzfile($fileName); // what is it?!
            unlink($fileName);
        }

3. You do not need to extract the zip, you can read it directly, including as a stream.
4. Show the process of creating the self :: UNZIP_DIR directory and what permissions it has.

[4ubi]

1. UNZIP_DIR = '/var/www/log'. premissions set chmod 777.
2. yield gzfile($fileName) - the zip archive contains gzip archives, I need to extract data from gzip archives (this is how the api Amplitudes works), for this I extract data from the zip archive and then iteratively read the data through the list of files

[Ne-Lexa]

Please attach an example zip file that is causing the problem. I will try to help you.

I figured it out! Thanks a lot for the explanation, item 2 from the post above opened my eyes and I solved my problem.

[Ne-Lexa]

Possible problem with file permissions due to the fact that the files have chmod 0600 in the zip archive and when unpacked it is also installed. I don't know the exact reasons yet, I can't reproduce this error.

I propose to rewrite the version without unzipping the archive.

<?php

require_once __DIR__.'/vendor/autoload.php';

function extractDataFromZip(string $zipContents)
{
    $zipFile = new \PhpZip\ZipFile();
    try {
        $zipFile->openFromString($zipContents);
        foreach ($zipFile as $entryName => $contents) {
            yield $entryName => gzdecode($contents);
        }
    } catch (Exception $exception) {
        throw $exception;
    } finally {
        $zipFile->close();
    }
}

$zipContents = file_get_contents(__DIR__ . '/issue62.zip');
$stream = \GuzzleHttp\Psr7\stream_for($zipContents);

foreach(extractDataFromZip((string) $stream) as $entryName => $content){
    var_dump([$entryName => $content]);
}

the problem was rights. Before exporting the files, I decided to create a temporary directory with the rights as in the archive. Thanks again for opening my eyes. Rays of gratitude from Siberia)
