JSON:

{
  "success": 1,
  "result": {
    "total": [
      {
        "standing_place": "1",
        "standing_place_type": "Promotion - NBA (Play Offs)",
        "standing_team": "Toronto Raptors",

$curl = curl_init();
curl_setopt_array( $curl, $curl_options );
$result = curl_exec( $curl );

$result = (array) json_decode($result);

var_dump($result);

    $result =  json_decode($result);
    foreach($result as $mydata)
    {    foreach($result->result as $myresult)
        {
           foreach($myresult->total as $total)
        {
             $standing_place_type = $total->standing_place_type;

Answer 1

What you have is basically there you just need to check that the total index exists prior to trying to use it:

foreach($result as $mydata) {
    if(!empty($mydata->total)){
        foreach($mydata->total as $total ){
            echo $total->standing_place_type . PHP_EOL;
        }
    }
}

First of all, if you're more familiar with PHP than JSON notation, try to print_r the result of json_decode to see how the structure is being converted. It should be like this :

$decodedJson = json_decode($json);
print_r($decodedJson);

// Result
stdClass Object
(
    [success] => 1
    [result] => stdClass Object
        (
            [total] => Array
                (
                    [0] => stdClass Object
...

Can you see? It's an object , with a result object , with a total object with an objects array .

Now, knowing that you can access PHP objects public properties like this $myObject->my_property and arrays you can iterate with foreach like in your sample, you would navigate this structure in PHP like this:

// Check if the object contains the expected structure
if ($decodedJson && isset($decodedJson->result) && isset($decodedJson->result->total)) {
    // Iterate over Total Array
   foreach ($decodedJson->result->total as $total) {
       // Print values
       echo "Standing_Place: {$total->standing_place} / Standing_Place_Type: {$total->standing_place_type}." . PHP_EOL;
   } 
}

Live sample .

Obs: On the JSON you posted, there is a curly bracket missing in the end. You can validate the json this site .
