Question

Please see my DEMO and answer my question: why date in values html on offset 2 not as date and it is a number?

DEMO: http://codepad.viper-7.com/r9FYnb

$data = array();
$data_1 = $_POST['data_1'];
$static = $_POST["static"];
foreach($static as $idx=>$val){
    $data[] = array(
          'data_1' => json_encode(Array($data_1[$idx*2],$data_1[$idx]*2+1)),
          'static' => $static[$idx]
           );
}

This is output:

Array
(
    [0] => Array
        (
            [data_1] => ["2011\/8\/02",4023] **//4023 !?**
            [static] => 12
        )

    [1] => Array
        (
            [data_1] => ["2011\/8\/09",4023] **// 4023!?** 
            [static] => 34
        )

    [2] => Array
        (
            [data_1] => ["2011\/8\/16",4023] **// 4023 !?**
            [static] => 56
        )

)

I’m not certain what you are trying to do here, but I see an inconsistency between how you manipulate $idx

'data_1' => json_encode(Array($data_1[$idx*2],$data_1[$idx]*2+1)),
//                              -----^^^^^^^^-------^^^^^^^^^^^^

For the second offset, perhaps you intend to modify $idx inside the []

'data_1' => json_encode(Array($data_1[$idx*2],$data_1[($idx*2)+1])),
//                               ---------------------^^^^^^^^^^^^

Sample output after modifying your demo:

Array
(
    [0] => Array
        (
            [data_1] => ["2011\/8\/02","2011\/8\/08"]
            [static] => 12
        )

    [1] => Array
        (
            [data_1] => ["2011\/8\/09","2011\/8\/15"]
            [static] => 34
        )
