Some Exctracted files have not content.

[kglazov]

Hello,
I am using PhpZip 3.1.3.
After extracting files form zip, some text files have no content due to following error.

PhpZip\Stream\ZipInputStream::readEntryContent() - ROOT/vendor/nelexa/zip/src/PhpZip/Stream/ZipInputStream.php, line 443
As a result following error throw an exception with CSC32 not matching error.

Also some of the csv files or xml gzinflate is uncompressing but some csv/xml file returning zero bites.

// get file as stream from GridFS by object id
$stream = $this->GridFS->openDownloadStream($oid);

// Opens a zip-archive from the stream. 
$zipFile = new \PhpZip\ZipFile();
$zipFile->openFromStream($stream)
 	    ->deleteFromRegex('/__MACOSX/')
	    ->deleteFromRegex('/.DS_Store/');


foreach($zipFile->getListFiles() as $entryName) {
     if ($zipFile->hasEntry($entryName) && !$zipFile->isDirectory($entryName)) {
				// get file content form compressed stream
				$contents = $zipFile->getEntryContents($entryName);
				
				// convert contents into resource stream for GridFS storage
				$stream = GuzzleHttp\Psr7\stream_for($contents);
				$resourceStream = StreamWrapper::getResource($stream);
				
				$filename = basename($entryName);
				$response['oids'][] = (string) $this->GridFS->addFile($filename,$resourceStream, $options);
    }
}

Hello,

Thank you for quick response. As requested I attached zip file .

I found that there issue with files only when I open zip file as a stream using GridFS. When I open zip form temp directory, such as $zipFile->openFile($file['tmp_name']), every think worked as expected with all type of files.

For example, $zipFile->openFromStream($stream) which obtained form GridFS as a zip stream the library can process only some text, csv, xml, images. In exception for executable, or cpp.

There could be issue with PHP gzinflate function.
