Get checked values from checkboxes

Question

I have this check boxes that I need to get its checked values:

In this example, I would expect to get Ubuntu , because it is checked.

<div class="checkbox">
    <label for="my_label_3-4">
        <input id="my_label_3-4" type="checkbox" value="5" name="my_label_3[]" aria-invalid="false"></input>
        Windows 7, 8
    </label>
</div>
<div class="checkbox">
    <label for="my_label_3-5">
        <input id="my_label_3-5" type="checkbox" value="6" name="my_label_3[]" aria-invalid="false"></input>
        Mac OS
    </label>
</div>
<div class="checkbox">
    <label for="my_label_3-6">
        <input id="my_label_3-6" type="checkbox" checked="" value="7" name="my_label_3[]" aria-invalid="false"></input>
        Ubuntu                                  
    </label>
</div>
<div class="checkbox">
    <label for="my_label_3-7">
        <input id="my_label_3-7" type="checkbox" value="8" name="my_label_3[]" aria-invalid="false"></input>
        FreeBSD
    </label>
</div>

How do I do so?

This is what I did so far, but hasn't return any result:

echo 'checkbox';
foreach ($html->find('my_label_3') as $id) {
    echo $id; // returns 'checkbox'
}

Using Simple HTML Dom for parsing process

try using the label to identify the nodes, as Ubuntu is not the value of the input . It is the text of the label , the value of that input is 7.

foreach ($html->find('label[for^="my_label_3-"') as $label) {
    if (!empty($label.find('input[checked]'))){
        echo $label->innertext;
    }
}
