Is it possible to pack and unpack a string on the fly?

Question

PHP

Good afternoon.
I googled for extensions for archiving data on the fly, but everything I found works only through files. The task is as follows: there is a long line of text, I would like to compress it using the zip algorithm or any other. But bypass file operations, but something like:

$archive = zipPack($data); //упаковка
$data = zipUnPack($archive); //распаковка

Are there ready-made extensions and functions for php or with files to dress up?
Thanks in advance to all who answer.
