Need help with json_encode

[HunterP]

Hi,

I grab 2 items from the database, the user name and a custom field. These two items are grouped into an array, which will be json_encoded to be used in javascript. When I check this json'ed javascript variable, I get to see something like :

var members = ([{"Hunter":"Algemeen"},{"Bart":"Algemeen"},{"mike":"Luchtvaart"}, (...)

So far, so good. At this point, I have two variables :

var member (which is "Hunter")
var type (which is "Algemeen")

I'd like to check my array members for the key "member" if the value equals "type".
But if I echo members[member], with or without single/double quotes, I get "undefined".

Any suggestions?

Ok, solved. Made it an object and now it's working.
