I have one array like this:

        Array
        (
           [1] => 0
           [2] => 1
           [4] => 1
           [5] => 4
           [6] => 2
           [7] => 0
           [8] => 2
           [9] => 7
           [10] => 2
           [11] => 2
           [12] => 2
           [17] => 12
           [18] => 17
           [19] => 0
           [20] => 19
           [21] => 20
           [22] => 20
           [23] => 20
           [24] => 0
         )

  • What have you tried? Also, your question does not seem clear to me. What's your expected result array? – Carlos Campderrós Jul 30 '13 at 06:24
  • What is your expected array(result) look like ? – Prasanth Bendra Jul 30 '13 at 06:30
  • 0 is my root element then corresponding key index find which is 1,7,19,24 then 1,7,19,24 value find in array so for 1 we get 2,4 and now this 2,4 is further check so for 2 we get 6,8,10,11,12 and this value further check so for 6,8,10,11 we get nothing so skip and for 12 we get 17 so this type i want to check value – darshan Jul 30 '13 at 06:39
  • my array is look like Array ( [0] => 1 [1] => 2 [2] => 6 [3] => 8 [4] => 10 [5] => 12 [6] => 17 and so on – darshan Jul 30 '13 at 06:41

$newTab = array();

foreach ($tab as $k => $v)
{
    $newTab[$v][] = $k;
}

Produces:

array (size=9)
  0 => 
    array (size=4)
      0 => int 1
      1 => int 7
      2 => int 19
      3 => int 24
  1 => 
    array (size=2)
      0 => int 2
      1 => int 4
  4 => 
    array (size=1)
      0 => int 5
  2 => 
    array (size=5)
      0 => int 6
      1 => int 8
      2 => int 10
      3 => int 11
      4 => int 12
