array keys from the original $myarr are now array values in the new
$myarr

The quotes are a problem

What Oli said is right but if you want to do it this way then David's
suggestion of using a foreach/implode/explode would work.

You could make the packing and unpacking, especially the unpacking,
easier and cleaner if you do not quote the keys/values and if you use
two seperators. For example & and = from url query strings.
