Any difference between these 2 forms of syntax?

Hi, I am wondering if there is any tangible difference between the following two commands: $x = $foo["status"]; $x = $foo['status']; The part in question being the use of ' or " around the "status" element of the array $foo. Both have the same end result in my case, I'm just purely wondering which is the correct form of syntax to use?
