Why don't you write the exact numbers in the brackets - <input type="text" name="name[0][you]" value="" /> and so on? — Todor Simeonov

try like this ==>

<form method="post" action="">
<input type="text" name="name[0][you]" value="" />
<input type="text" name="name[0][he]" value="" />
<input type="text" name="name[0][she]" value="" />
<input type="text" name="name[1][you]" value="" />
<input type="text" name="name[1][he]" value="" />
<input type="text" name="name[1][she]" value="" />
<button type="submit">go</button>
</form>

OR

<form method="post" action="">
    <?php $n = 2; // how many interval you want
    for ($i = 0; $i < $n; $i++) {
        ?>
        <input type="text" name="name[<?php echo $i; ?>][you]" value="" />
        <input type="text" name="name[<?php echo $i; ?>][he]" value="" />
        <input type="text" name="name[<?php echo $i; ?>][she]" value="" />

<?php } ?>
</form>

If you want to output an array with two children then set the keys manually, name[0] for the first three inputs and name[1] for the last three.

so there's no way to do this without using key number in the input ?

Everytime you write name="[][key]" php increment automatic the key. if you write syntax like [] php increment the index of array.

Small explation For example:
If you write an array like this

$array[] = "msg1";
$array[] = "msg2";
$array[] = "msg3";

$array length will be 2 (3 elements because it starts from 0) and it is same as

$array[0] = "msg1";
$array[1] = "msg2";
$array[2] = "msg3";

This is different from above

$array[0] = "msg1";
$array[1] = "msg2";
$array[1] = "msg3";

This array will have only 1 length (2 elements only)

Solution of your question is :

<form method="post" action="">
  <input type="text" name="name[0][you]" value="" />
  <input type="text" name="name[0][he]" value="" />
  <input type="text" name="name[0][she]" value="" />
  <input type="text" name="name[1][you]" value="" />
  <input type="text" name="name[1][he]" value="" />
  <input type="text" name="name[1][she]" value="" />
  <button type="submit">go</button>
</form>
