convert php array into single JSON object

Question

I converted a PHP array into JSON, using json_encode. I checked the console, and the objects are displaying in array, but as individual objects.

 [ { Object { 03-13-2012="Jazz"}, Object { 07-19-2012="Pop"}, ... ]

How can I convert this array into one object, like this (in PHP or jQuery):

Object { 03-13-2012="Jazz", 07-19-2012="Pop"}

Edit: Here's the beginning of my print_r for the PHP array:

Array
(
    [0] => Array
        (
            [03-13-2012] => Jazz
        )

    [1] => Array
        (
            [07-19-2012] => Pop
        )
)

Simply merge each of the inner arrays in PHP or the objects in JS. Better yet, create the array in the correct format from the beginning! — Felix Kling

Don't be afraid of loops

$output = array();
foreach($data as $v) {
    $output[key($v)] = current($v);
}
echo json_encode($output, 128);

@Baba I am using return instead of echo because I need json response for mobile applications but return only returns last value of an array can you tell me how I can return whole array?

In general, you need to prepare such a PHP array, which then should be json_encode and passed along to the server:

$data = array(

  '03-13-2012' => 'Jazz',
  '07-19-2012' => 'Pop',

);

echo json_encode( $data );
exit;

You'll want to iterate over the indexed array making the keys of an associative array found therein into keys in a second associative array.

Assumption: You're starting with a JSON string, and you want to end up with a JSON string.

Warning: If you encounter duplicates you will overwrite.

Here's an example of what I'm talking about:

<?php
$foo = json_decode('[{"abc":"A123"},{"xyz":"B234"}]');
$bar = array();
foreach ($foo as $f) {
        foreach ($f as $k => $v) {
                $bar[$k] = $v;
        }
}

echo json_encode($foo)."\n";
echo json_encode($bar)."\n";
?>
