You can create a function like this:

function countRes($arr) {
    return is_array(end($arr)) ? count($arr) : 1;
}

$arr1 = array("Id" => 1779, "SupplierId" => 1809, "SupplierName" => "cccccc");

$arr2 = array(array("Id" => 2020, "SupplierId" => 1809, "SupplierName" => "vvv"),
              array("Id" => 2058, "SupplierId" => 1809, "SupplierName" => "bbb"),
              array("Id" => 2063, "SupplierId" => 1809, "SupplierName" => "xx"));

echo countRes($arr1); // 1
echo countRes($arr2); // 3

It checks if the last element is an array, and returns the number of arrays in the resulting array. Otherwise it returns 1 because the resulting array itself contains the data.
