Hello, I have this array that is inside another array and I would like to read it, but I will never know how many keys the array items will have, since it can always be increased or decreased, but what I was trying to do was

     foreach ($data->items as $row)
        {
            foreach($row as $i => $a)
            {
                echo '<div>'. $i." ".$a .'</div>';
            }
        }

But I do not know how to handle the increment of $ a

You should do this recursively.

Taking advantage of code for a recursive menu in html that I did before ( link ), and adjusting minimally to this case:

function recusive_list($items, $c) {
    $c += 1;
    $text = '';
    if (is_object($items))
        $items = get_object_vars($items);
    foreach ($items as $key => $item) {
        if(!is_array($item))
            $text .= str_repeat('*', $c) . ' ' .$key. ' - ' .$item. "\n";
        else
            $text .= recusive_list($item, $c);
    }
    return $text;
}

$items = [
    [
        'href' => 'www.item1',
        'name' => 'Item1',
        'childs' => [
            [
                'href' => 'www.item1.1',
                'name' => 'Item1.1',
                'childs' => []
            ]
        ]
    ],
    [
        'href' => 'www.item2',
        'name' => 'Item2',
        'childs' => [
            [
                'href' => 'www.item2.1',
                'name' => 'Item2.1',
                'childs' => [
                    [
                        'href' => 'www.item2.1.1',
                        'name' => 'Item2.1.1',
                        'childs' => []
                    ],
                    [
                        'href' => 'www.item2.1.2',
                        'name' => 'Item2.1.2',
                        'childs' => [
                            [
                                'href' => 'www.item2.1.2.1',
                                'name' => 'Item2.1.2.1',
                                'childs' => []
                            ]
                        ]
                    ]
                ]
            ]
        ]
    ],
    [
        'href' => 'www.item3',
        'name' => 'Item3',
        'childs' => []
    ],
];

echo recusive_list($items, 0);

Output:

** href - www.item1
** name - Item1
**** href - www.item1.1
**** name - Item1.1
** href - www.item2
** name - Item2
**** href - www.item2.1
**** name - Item2.1
****** href - www.item2.1.1
****** name - Item2.1.1
****** href - www.item2.1.2
****** name - Item2.1.2
******** href - www.item2.1.2.1
******** name - Item2.1.2.1
** href - www.item3
** name - Item3

PS: Note that you do not really need the variable $c (second parameter of the recusive_list function), just use it to make it easier to see:
