如何使用ZF2 Filter压缩文件内容？

Question

How can I make a compressed archive from a local file with ZF2 Zend\Filter\Compress?

I wrote this code:

$filter = new Zend\Filter\Compress(array(
    'adapter' => 'Gz',
    'options' => array(
        'archive' => "/local/lnx/archive.gz",
    ),
));
$compressed = $filter->filter("/local/lnx/file.txt");

It make a new archive in /local/lnx/ but it contain a file without extension that contain the string /local/lnx/file.txt. But I don't want that, I would like to have an archive that contain the FILE file.txt not its name. Where is my error?

If I got this right then what's happening is that you're setting the archive content to be the string /local/lnx/file.txt and not the file that resides under that path. Take a look at the method definition. It looks like you need to get the file contents (e.g. with file_get_contents function) and pass that to the filter method.
