Php到json不传递所有数组（或json不显示所有接收的值）

As see for the first and the third row all fields filled, for the second row some fields left blank.

Filled values with

$.post("__php_file.php", { 'number_of_input_row': number_of_input_row, 'date_day': date_day, 'date_month': date_month, 'date_year': date_year, 'currency': currency }, function(data, success) {

$('#currency_load1').html(data[0].FinalCurrencyRate);
$('#currency_load2').html(data[1].FinalCurrencyRate);
$('#currency_load3').html(data[2].FinalCurrencyRate);

}, "json");

send to php file, process and get such php array

Array
(
    [0] => Array
        (
            [CurrencyAbbreviation] => AUD
            [DateOfCurrencyRate] => 2013-07-11
            [NumberOfInputRow] => 1
            [FinalCurrencyRate] => 0.506
        )

    [2] => Array
        (
            [CurrencyAbbreviation] => CAD
            [DateOfCurrencyRate] => 2013-07-25
            [NumberOfInputRow] => 3
            [FinalCurrencyRate] => 0.516
        )

)

json array is this

{
"0":{"CurrencyAbbreviation":"AUD","DateOfCurrencyRate":"2013-07-11","NumberOfInputRow":"1","FinalCurrencyRate":"0.506"},
"2":{"CurrencyAbbreviation":"CAD","DateOfCurrencyRate":"2013-07-25","NumberOfInputRow":"3","FinalCurrencyRate":"0.516"}
}

So far all ok. But below is described problem

Get back results and display here

<div id="currency_load1"></div>
<div id="currency_load2"></div>
<div id="currency_load3"></div>

However get displayed only FinalCurrencyRate for AUD or [0] => Array.

Question is: what need to correct to get displayed also FinalCurrencyRate from [2] => Array? As you see in php such array presents, but is not passed to json...

If fill all fields for the second row, then get displayed all three arrays.

Update Tried this

$('#currency_load1').html(data[0].FinalCurrencyRate);
$('#currency_load2').html("test to check");
$('#currency_load3').html(data[2].FinalCurrencyRate);

And all works. As understand within jquery need to create condition like if FinalCurrencyRate is empty, then $('#currency_load2').html("0");? But why such json/jquery behavior?
