I have a PHP multidimensional array which looks like this:

Array
(
[EUR] => Array
    (
        [title] => Euro
        [symbol_left] => 
        [symbol_right] =>  €
        [decimal_point] => .
        [thousand_point] => ,
        [decimal_places] => 2
        [currency_value] => 1.32306004
    )

[USD] => Array
    (
        [title] => United States Dollars
        [symbol_left] => $
        [symbol_right] => 
        [decimal_point] => .
        [thousand_point] => ,
        [decimal_places] => 2
        [currency_value] => 1.00000000
    )

)

when I encode it using PHP's json_encode() it looks like this:

{"EUR":{"title":"Euro","symbol_left":"","symbol_right":" €","decimal_point":".","thousand_point":",","decimal_places":"2","currency_value":"1.32306004"},"USD":{"title":"United States Dollars","symbol_left":"$","symbol_right":"","decimal_point":".","thousand_point":",","decimal_places":"2","currency_value":"1.00000000"}}

I have tried some of the standard ways to iterate through this is jQuery such as the following two:

for(item in json_currencies) {
        var cash = json_currencies[item];
        alert(cash.currency_value);
    }

$.each(json_currencies, function(i,obj) {
        alert(obj.currency_value);
    });

The problem with both of these is that they will alert the two 'currency_value' items three times each, instead of just once.

What is the correct way to iterate through this jSON?

The first example works correctly for me. Didn't try the second. – Michael Berkowski Apr 7 '12 at 3:20

Tried the second and it works too... fiddle – Michael Berkowski Apr 7 '12 at 3:23
yes, they work, however they alert THREE TIMES for each item rather than just once. – Billy Apr 7 '12 at 3:25
Nope, they output only once for me. Chrome & FF both fine. – Michael Berkowski Apr 7 '12 at 3:27
What is "each item"? It alerts once for USD and another one for EUR. Isn't that what you're looking for? – bfavaretto Apr 7 '12 at 3:28

If you are using Google Chrome hit F12. Go to console tab.

in your code: 

$.each(json_currencies, function(i,obj) {
    //alert(obj.currency_value);
    console.log(obj.currency_value)  //console.log()
});

you should see the output. This is a good way to show the errors/outputs

I can see the output perfectly with the alerts. There are no errors. Please read my question better plus my reply above so you understand the problem. – Billy Apr 7 '12 at 3:28
Oops I forgot what I'm about to answer: "use console.log() instead of alerts" - this is the best way to show outputs and errors including objects - this is what I meant. – Peter Wateber Apr 7 '12 at 3:34
