did this
$from = array( 'rgb' => '000000');
fix it for you?

which version of PHP on the old/new servers?

I would have to guess that since you didn't initialize $to and $from as
arrays, they didn't get echo'ed as such.

that's at least for the typing issue. I'm not sure why the other results
came up the way they did, even without declaring the arrays.

A good reason to always initialize arrays before populating them.
either.
If you were going to be adding more entries to the same array, I would use
$foo = array()
and array_push()
rather than using $foo = array('key' => 'value')
each time
Wouldn't the latter re-initialize the array and wipe out old values?
