JSON

$json = '{{"var1":"9","var2":"16","var3":"16"}, 
               {"var1":"8","var2":"15","var3":"15"}}';

What I have tried:

JSON

$json = '{{"var1":"9","var2":"16","var3":"16"}, 
                {"var1":"8","var2":"15","var3":"15"}}';
    $decoded = json_decode($json);
    foreach ($decoded as $k => $v) {
        echo "<pre>";
        print_r($k)."<br>";
        echo "";    }

It's not much of a question you've asked, but I will say that that isn't valid JSON. If it's meant to be an array of values then it would need to be:

'[{"var1":"9","var2":"16","var3":"16"}, 
{"var1":"8","var2":"15","var3":"15"}]';

Note that I replaced the first and last '{' and '}' with '[' and ']' respectively, because that's what signifies an array in JSON.

Also your foreach loop is printing the $k variable which is likely to be just the index of the element in the array, not that value at that specific index.
