Answer 1

Use a 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 go 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 do not have a numeric key or other index, you can change the destination with 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']);

Answer 2

If you just debug the contents of your nested array and want to look at it in a friendly way, you can try:

print_r($my_nested_array) - .

var_dump($my_nested_array) - .

Answer 3

, , foreach $nos3 ( foreach)

$counts = 0;
foreach($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 ++;
}

    $nos = $_POST['nos'];
    $nos2 = $_POST['nos2'];
    $nos3 = $_POST['nos3'];

    foreach($nos as $nbs) {
        echo $nbs . "<br />";   

        foreach($nos2 as $nbs2) {
            echo "&nbsp;&nbsp;&nbsp;" . $nbs2 . "<br />";

            foreach($nos3 as $nbs3) {
                echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;" . $nbs3 . "<br />";
                break; // stop the looping, in this case after the first time
            }

            break; // stop the looping, in this case after the first time
        }

        break; // stop the looping, in this case after the first time
    }
