Save Input fields as array in PHP

I have Input fields that result in an array after POST:

<tr>
<td><input name="time['day'][]" value="1"></td>
<td><input name="time['from][]" value="1"></td>
<td><input name="time['to][]" value="1"></td>
</tr>

<tr>
<td><input name="time['day'][]" value="2"></td>
<td><input name="time['from][]" value="2"></td>
<td><input name="time['to][]" value="2"></td>
</tr>

This will be return:

Array (

['day'] => Array
    (
        [0] => 1
        [1] => 2
    )

['from] => Array
    (
        [0] => 1
        [1] => 2
    )

['to] => Array
    (
        [0] => 1
        [1] => 2
    )

)

But I would like to have this:

Array ( [1] => Array

    (
        ['day'] => 1
        ['from] => 1
        ['to] => 1
    )

[2] => Array
    (
        ['day'] => 2
        ['from] => 2
        ['to] => 2
    )

)

I get this if I use:

<tr>
<td><input name="time[1]['day']" value="1"></td>
<td><input name="time[1]['from]" value="1"></td>
<td><input name="time[1]['to]" value="1"></td>
</tr>

<tr>
<td><input name="time[2]['day']" value="2"></td>
<td><input name="time[2]['from]" value="2"></td>
<td><input name="time[2]['to]" value="2"></td>
</tr>

But here comes the problem. I want to add new rows dynamicly (with JS) and would need to add always +1 to the first index.

How could I achive the second result without having to set the first index manually?

Using script to write script is better than to write each. Just a concept to go with, you can use jquery to write into div for better result. 

<script>
function callInput( i ) {
  document.write( "<tr><td><input name='time[" + i + "][day]' value='" + i + "'></td><td><input name='time[" + i + "][from]' value='" + i + "'></td><td><input name='time[" + i + "][to]' value='" + i + "'></td></tr>" );
}

function callRow( i ) {
  document.write( "<table>" );
  for( a = 0; a < i; a++ ) {
    callInput( a );
  }
  document.write( "</table>" );
}
</script>

<body onload="callRow( 4 )">

You can keep your html like this - 

<tr>
    <td><input name="time['day'][]" value="1"></td>
    <td><input name="time['from'][]" value="1"></td>
    <td><input name="time['to'][]" value="1"></td>
</tr>

<tr>
    <td><input name="time['day'][]" value="2"></td>
    <td><input name="time['from'][]" value="2"></td>
    <td><input name="time['to'][]" value="2"></td>
</tr>

After you get the values on server, lets say in GET array - 

<?php 
    $myfinalarray = array();
    foreach ($_GET['time'] as $key => $value) {
        foreach ($value as $k => $v) {
            $myfinalarray[$k][$key] = $v;
        }
    }
    print_r($myfinalarray);
?>

Output - 

Array
(
    [0] => Array
        (
            ['day'] => 1
            ['from'] => 1
            ['to'] => 1
        )

    [1] => Array
        (
            ['day'] => 2
            ['from'] => 2
            ['to'] => 2
        )

)
