Use for loop instead :

    $nos = $_POST['nos'];
    $nos2 = $_POST['nos2'];
    $nos3 = $_POST['nos3'];
    for($i = 0 ; $i < count($nos) ; $i++){
      if(isset($nos[$i])) echo $nos[$i]."<br>";
      if(isset($nos2[$i])) echo "&nbsp;&nbsp;&nbsp;".$nos2[$i]."<br>";
      if(isset($nos3[$i])) echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;".$nos3[$i]."<br>";
    }

Or foreach like this

    $nos = $_POST['nos'];
    $nos2 = $_POST['nos2'];
    $nos3 = $_POST['nos3'];
    foreach($nos as $i => $n){
      echo $n."<br>";
      if(isset($nos2[$i])) echo "&nbsp;&nbsp;&nbsp;".$nos2[$i]."<br>";
      if(isset($nos3[$i])) echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;".$nos3[$i]."<br>";
    }

EDIT

If you haven't numeric key or different index, you can change assignation by array_values http://php.net/manual/en/function.array-values.php

    $nos = array_values($_POST['nos']);
    $nos2 = array_values($_POST['nos2']);
    $nos3 = array_values($_POST['nos3']);

Try this, use counter, so it will display foreach of $nos3(last foreach loop) value as expected output

$counts = 0;
foreach($nos as $nbs)
{   
    echo $nbs."<br>";   
    foreach($nos2 as $nbs2)
    {
        echo "&nbsp;&nbsp;&nbsp;".$nbs2."<br>";
        $sub_counts = 0;
        foreach($nos3 as $nbs3)
        {
            if($counts == $sub_counts)
            {
                echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;".$nbs3."<br>";
            }           
            $sub_counts ++;
        }
        break;
    }
    $counts ++;
}

i hope it will be helpful.

If you are just debugging the contents of your nested array and you want to look at it in a human friendly way you could try either:

print_r($my_nested_array) - see here

or

var_dump($my_nested_array) - see here
