I am trying to access withing foreach some of the key values in the example JSON below.
{
  "Realtime Currency Exchange Rate": 
    {
        "1. From_Currency Code": "EUR",
        "2. From_Currency Name": "Euro",
        "3. To_Currency Code": "USD",
        "4. To_Currency Name": "United States Dollar",
        "5. Exchange Rate": "1.14122552",
        "6. Last Refreshed": "2018-08-14 05:07:51",
        "7. Time Zone": "UTC"
    },
    {
        "1. From_Currency Code": "USD",
        "2. From_Currency Name": "United States Dollar",
        "3. To_Currency Code": "EUR",
        "4. To_Currency Name": "Euro",
        "5. Exchange Rate": "0.87692400",
        "6. Last Refreshed": "2018-08-14 05:09:17",
        "7. Time Zone": "UTC"
    }
}
The problem is that the keys are having spaces.
My FOREACH looks like this
$json = json_decode($data);    
$json_response = array();
foreach ($json->Realtime Currency Exchange Rate as $row) {
        $row_array = array();     
        $row_array['From'] = $row->1. From_Currency Code;        
        $row_array['To'] = $row->3. To_Currency Code;
        $row_array['value'] = $row->5. Exchange Rate;                           
       array_push($json_response, $row_array); 
 }
I have tried to use the key in the foreach statement as ['Realtime Currency Exchange Rate'], [Realtime Currency Exchange Rate], [Realtime.Currency.Exchange.Rate] and anything else I could find in here, but none of them worked.
EDIT Also tried like this but it didn't work
foreach ($json->{'Realtime Currency Exchange Rate'} as $row) {
    $row_array = array();
        $row_array['From'] = $row->{'1. From_Currency Code'};
   array_push($json_response, $row_array); //push the values in the array
}
But this SOLUTION worked
foreach ($json as $row) {
    $row_array = array();
        $row_array['From'] = $row->{'1. From_Currency Code'};
   array_push($json_response, $row_array); //push the values in the array
}
Any idea how I can access the key and its value? Thanks
