PHP json_encode issue

I have a bunch of values and a PHP array and I need to convert it to a JSON value for posting via CURL to parse.com

The problem is that PHP arrays are converted to JSON objects (string as key and value, vs string as just value)

I end up with

{"showtime":{"Parkne":"1348109940"}}

Rather then

{"showtime":{Parkne:"1348109940"}}

And parse complains that this is a object not an array and therefore won't accept it.

As

{"showtime":{"Parkne":"1348109940"}}

is a JSON object (key = a string)

Is there anyway to do this using json_encode? Or some solution?

It sounds like you need to take your single object and wrap it in an array.

Try this:

// Generate this however you normally would
$vals  = array('showtime' => array("Parkne" => "1348109940"));

$o = array(); // Wrap it up ...
$o[] = $vals; // ... in a regular array

$post_me = json_encode($o);

That's the JSON spec: Object keys MUST be quoted. While your first unquoted version is valid Javascript, so's the quoted version, and both will parse identically in any Javascript engine. But in JSON, keys MUST be quoted. http://json.org

Followup:

show how you're defining your array, unless your samples above ARE your array. it all comes down to how you define the PHP structure you're encoding.

// plain array with implicit numeric keying
php > $arr = array('hello', 'there');
php > echo json_encode($arr);
["hello","there"]   <--- array

// array with string keys, aka 'object' in json/javascript
php > $arr2 = array('hello' => 'there');
php > echo json_encode($arr2);
{"hello":"there"} <-- object

// array with explicit numeric keying
php > $arr3 = array(0 => 'hello', 1 => 'there');
php > echo json_encode($arr3);
["hello","there"]  <-- array

// array with mixed implicit/explicit numeric keying
php > $arr4 = array('hello', 1 => 'there');
php > echo json_encode($arr4);
["hello","there"] <-- array

// array with mixed numeric/string keying
php > $arr5 = array('hello' => 'there', 1 => 'foo');
php > echo json_encode($arr5);
{"hello":"there","1":"foo"}   <--object

You can convert your array to JSON using json_encode assuming your array is not empty you can do it like this 

 $array=();
 $json = json_encode($array);
 echo $json;

Blind shot... I have the impression that your PHP data structure is not the one you want to begin with. You probably have this:

$data = array(
    'showtime' => array(
        'Parkne' => '1348109940'
    )
);

... and actually need this:

$data = array(
    array(
        'showtime' => array(
            'Parkne' => '1348109940'
        )
    )
);

Feel free to edit the question and provide a sample of the expected output.
