Answer 1

Just achieved this using https://github.com/dankogai/js-deflate However the postdata for whatever reason will strip the + signs and replace them with spaces.

To send the data via javascript:

params.mapdata=  btoa(RawDeflate.deflate(JSON.stringify(mapdata)));

To receive the data via php:

$value = gzinflate(base64_decode(preg_replace('/\s/', '+',$value)));
