    {    echo '<option value=' . $option->CurrencyDescription . '>' . $option->CurrencyDescription . '</option>';  
}
echo '</select>';


           ?>

$jsonres is actually an array.

This is because true is being passed as the second parameter to json_decode. If you, in fact, do want $jsonres to be an object, then just use json_decode($jsonObject);.

An easy way to check what your variable contains is to use the var_dump function.

$jsonres = json_decode($jsonObject);
var_dump($jsonres);

Also, be sure you have error_reporting turned on and set to E_ALL. The following code, $jsonres->Data, should be causing PHP to emit a "PHP Notice".
