Is there some way to convert an array to something that is transmitable and reverable? So it could be like

$array = array('hey', 'what', 'is', 'up');
//convert to string
$array = function($array);
echo $array;
// equals something non-human readable
// ex asdklj92vlkan1kljdfvj2
$array = reverse($array);
print_r($array);
// returns 'hey', 'what', 'is', 'up'

Wouldn't that just be encrypting?
I guess there are plenty of functions for that, and millions of ways to do it.

It doesn't need to be secure or anything. What I ended up doing is

base64_encode(serialize($array))
