Answer

stdClass Object is telling us you have an object inside your array. so your $response structure looks like this in code:

[
    {
        "service": "text",
        "reference": 12345678
    }
]

try this:

$response = json_decode($result);
foreach($response as $value){
    echo $value->units;
}

in response yo your comment on this answer:

if you wanted to neaten this up you could replace the second reference to $response->data with $values:

$values = $response->data;
foreach($values as $value){
    echo "<table>
    <td>$value->reference</td>
    <td>$value->message</td>
    <td>$value->sender</td>
    <td>$value->mobile</td>
     <td>$value->status</td>
     <td>$value->units</td>
    </table>";
}

I suspect this is what you were going for when you wrote it out, but essentially you were declaring $values and then not using it…. then making a call to the same collection as $values.
