title: JavaScript string compression + PHP decompression
body: <p>I'm looking for a solution to compress string in JavaScript, send it using GET (jsonp), and decompress back using PHP. The best would be to have fast code and good compression.</p>
  
  <p>I've found <a href="https://github.com/pieroxy/lz-string" rel="noreferrer">lz-string</a> library, but looks like it does not have PHP backend. Any other similar libraries or PHP implementation of lz-string?</p>
