JSON Key Value Pairs within an Array in PHP using the json_encode() Function

Question

I am trying to get my JSON output in a particular syntax

here is my code:

$ss = array('1.jpg', '2.jpg');
$dates = array('eu' => '59.99', 'us' => '39.99');
$array1 = array('name' => 'game1', 'publisher' => 'ubisoft', 'screenshots' => $ss, 'dates' => $dates, 'added' => '2014/12/31');

echo json_encode($array1);

it gives me this output:

{
name: "game1",
publisher: "ubisoft",
screenshots: [
"1.jpg",
"2.jpg"
],
dates: {
eu: "59.99",
us: "39.99"
},
],
added: "2014/12/31"
}

which is CLOSE but, not exactly what I need. The dates need to be formatted slightly different. Like this:

{
name: "game1",
publisher: "ubisoft",
screenshots: [
"1.jpg",
"2.jpg"
],
dates: [
{
eu: "59.99"
},
{
us: "39.99"
}
],
added: "2014/12/31"
}

I have tried adding more dimensions to the $dates array, but that still doesn't give quite the right output. Unfortunately the php manual for the json_encode() function doesn't provide much help and there is very little documentation on more complex json encodes within php that i have found with google searching.

Any help would be greatly appreciated.

Why do you want objects with different keys in the dates: array? Won't that make it difficult to access the values, since you don't know the key? — Barmar

@Barmar - Thanks for your quick reply. Sorry, I have edited the desired output. It was hand typed and I got it wrong. Also, a friend of mine who works with Json has given me a very specific specification of how he wants the Json to read. I know almost nothing about Json or why he needs it the way he does, so I'm actually quite surprised I've even made it this far! — Lee Ginger-Ninja McCarthy

The original output also has mismatched brackets. There's no opening [ for the closing ] above added:. — Barmar

Change the $dates assignment to:

$dates = array(array('eu' => '59.99'), array('us' => '39.99'));

you will need to do something like this ( wrap each date in its own assoc array)

array( 
   array('eu' => '59.99'),
   array('us' => '39.99')
);

Then it will encode correctly as

[
   {'eu' : '59.99'},
   {'us' : '39.99'}
]

It's simple really, arrays with numeric( natural ) keys are just [ ], associative arrays are { key : value }

$ss = array('1.jpg', '2.jpg');
$dates[] = array('eu' => '59.99');
$dates[]=array('us' => '39.99');
$array1 = array('name' => 'game1', 'publisher' => 'ubisoft', 'screenshots' => $ss, 'dates' => $dates, 'added' => '2014/12/31');
echo json_encode($array1);
