Php – My function to display array structure in a comfortable way

I wrote my own function to display array structure in a comfortable way.
It show’s array like that:

$data:
$data[id] = 3

$config:
$config[last_offer_day] = 01.07.2023
and etc.

i think my code is too cumbersome. Is there a way to make it smaller and simpler?

    function darr ($var, $name = '')
    {
    if($name) $out = '<b>'.$name.':</b><br>';
    $len = 250;
            
    foreach($var as $key1=>$val1)
    {
    $key1 = $name ? '['.$key1.']' : '$'.$key1;
    
    if(is_array($val1) || is_object($val1))
    {
    if(count($val1) > 1) $out .= '<br>'.$key1.':<br>';
        
    foreach($val1 as $key2=>$val2)
    {
    if(is_array($val2) || is_object($val2))
    {           
    foreach($val2 as $key3=>$val3)
    {
    if(is_array($val3) || is_object($val3))
    {
    foreach($val3 as $key4=>$val4)
    {
    if(is_array($val4) || is_object($val4))
    {
    foreach($val4 as $key5=>$val5)
    {
    if(is_array($val5) || is_object($val5))
    {
    foreach($val5 as $key6=>$val6)
    {
    if(is_array($val6) || is_object($val6))
    {
    foreach($val6 as $key7=>$val7)
    {
    $out .= $name.$key1.'['.$key2.']['.$key3.']['.$key4.']['.$key5.']['.$key6.']['.$key7.'] = '.trim((mb_strlen($val7) > $len ? mb_substr($val7, 0, $len).'...' : $val7),' n').'<br>';
    }
    } else $out .= $name.$key1.'['.$key2.']['.$key3.']['.$key4.']['.$key5.']['.$key6.'] = '.trim((mb_strlen($val6) > $len ? mb_substr($val6, 0, $len).'...' : $val6),' n').'<br>';
    }
    } else $out .= $name.$key1.'['.$key2.']['.$key3.']['.$key4.']['.$key5.'] = '.trim((mb_strlen($val5) > $len ? mb_substr($val5, 0, $len).'...' : $val5),' n').'<br>';
    }
    } else $out .= $name.$key1.'['.$key2.']['.$key3.']['.$key4.'] = '.trim((mb_strlen($val4) > $len ? mb_substr($val4, 0, $len).'...' : $val4),' n').'<br>';
    }
    } else $out .= $name.$key1.'['.$key2.']['.$key3.'] = '.trim((mb_strlen($val3) > $len ? mb_substr($val3, 0, $len).'...' : $val3),' n').'<br>';
    }
    } else $out .= $name.$key1.'['.$key2.'] = '.trim((mb_strlen($val2) > $len ? mb_substr($val2, 0, $len).'...' : $val2),' n').'<br>';
    }
    } else $out .= $name.$key1.' = '.trim((mb_strlen($val1) > $len ? mb_substr($val1, 0, $len).'...' : $val1),' n').'<br>';
    }
            
    return $out;
    }

And here some unuseful text to say that my post not looks like your post is mostly code.

    Thank you, James. It woks fine but has little problem. If is object i get error: not countable in line:

    if (count($val) > 1) {

    Here is my little fix:

    function darr($var, $name = '')
{
    $out = '';
    $len = 250;

    if ($name) 
    {
        $out .= '<b>' . $name . ':</b><br>';
    }

    if (is_array($var) || is_object($var)) 
    {
        foreach ($var as $key => $val) 
        {
            $keyString = is_numeric($key) ? '[' . $key . ']' : "['" . $key . "']";
            $displayName = $name . $keyString;

            if (is_array($val) || is_object($val)) 
            {
                if (is_array($val) && count($val) > 1) $out .= '<br>';
                $out .= darr($val, $displayName);
            } else {
                $out .= $displayName . ' = ' . trim((mb_strlen($val) > $len ? mb_substr($val, 0, $len) . '...' : $val), " n") . '<br>';
            }
        }
    }

    return $out;
}

    This uses recursive calls to handle nested arrays or objects. You don’t need multiple nested loops, and it also properly handles the display of numeric keys in square brackets.

    function darr($var, $name = '')
{
    $out = '';
    $len = 250;

    if ($name) {
        $out .= '<b>' . $name . ':</b><br>';
    }

    if (is_array($var) || is_object($var)) {
        foreach ($var as $key => $val) {
            $keyString = is_numeric($key) ? '[' . $key . ']' : "['" . $key . "']";
            $displayName = $name . $keyString;

            if (is_array($val) || is_object($val)) {
                if (count($val) > 1) {
                    $out .= '<br>' . darr($val, $displayName);
                } else {
                    $out .= darr($val, $displayName);
                }
            } else {
                $out .= $displayName . ' = ' . trim((mb_strlen($val) > $len ? mb_substr($val, 0, $len) . '...' : $val), " n") . '<br>';
            }
        }
    }

    return $out;
}
