[php-src] Issue #11594: in-memory ZipArchive

Issue: https://github.com/php/php-src/issues/11594 Author: rgeraads ### Description Currently ZipArchive relies on the filesystem, for both opening and extracting files. Would it be possible to have it work with files (or data) in memory? Or is that a limitation of the underlying zip library? Below is an example of ZipArchive not being able to open files from a virtual file system (probably because it's a stream). ``` $vfs = \org\bovigo\vfs\vfsStream::setup(); copy('foo.zip', $vfs->url() . '/foo.zip'); var_dump(file_get_contents($vfs->url() . '/foo.zip')); // file contents appears $zip = new ZipArchive(); $zip->open($vfs->url() . '/foo.zip'); $zip->extractTo(__DIR__); // Uncaught ValueError: Invalid or uninitialized Zip object $zip->close(); ```
