PHP解压缩字符串

Question

I'm loading in a Google Drive spreadsheet via the API into PHP. The request returns the XLSX spreadsheet and I need to unzip it. To save me writing the response to a temporary and then calling, say, zip_open(), is there a way I can just pass such method a string?

Answer 1

I think your best option is to create a temporary file and then to unzip it.

// Create a temporary file which creates file with unique file name
$tmp = tempnam(sys_get_temp_dir(), md5(uniqid(microtime(true))));

// Write the zipped content inside
file_put_contents($tmp, $zippedContent);

// Uncompress and read the ZIP archive
$zip = new ZipArchive;
if (true === $zip->open($tmp)) {
    // Do whatever you want with the archive... 
    // such as $zip->extractTo($dir); $zip->close();
}

// Delete the temporary file
unlink($tmp);
