Ok, so I've got two arrays planned - which will be sorted based on a date or timestamp, as so:
array([date] => "8/12/12", [rating] => 300)
and lets say a second array looks like this:
array([date] => "8/12/12", [rating2] => 600)
I want to combine these two as such:
array([date] => "8/12/12", [rating] => 300, [rating2] => 600)
What would be the most effective way to do this?
