从onclick = function（）获取按钮的内容

Question

how can I access the content of a button?

HTML:

<form method="post">
    <button type="submit"  name="delete" class="btn btn-lg btn-danger" onclick="deleletconfig('.$test[0].')">delete</button>
</form>

and this is the PHP:

if (isset($_POST['delete']))
    echo $_POST['delete'];

I need to have the result of "deleletconfig('.$test[0].')" in the php code.
