How to get unique array in php

I'v an array like this:

Array([0] => 1,[1] => 2,[2] => 3,[3] => 3,[4] => 4,[5] => 5,[6] => 5,[7] => 6,[8] => 6,[9] => 6,[10] => 7,[11] => 8,[12] => 8,[13] => 8,[14] => 8,[15] => 9,[16] => 9,[17] => 9,[18] => 9,[19] => 9)

but the results I want like this:

Array([0] => 1,[1] => 2,[3] => 3,[4] => 4,[6] => 5,[9] => 6,[10] => 7,[14] => 8,[19] => 9)

This not only eliminates the value of the same array, but the same value that appears to be the value of the index / key of the last of the same value. anyone can help me?

ok, I've got the answer I want, thank you to all who have tried to help me.

$str = Array('0' => 1,'1' => 2,'2' => 3,'3' => 3,'4' => 4,'5' => 5,'6' => 5,'7' => 6,'8' => 6,'9' => 6,'10' => 7,'11' => 8,'12' => 8,'13' => 8,'14' => 8,'15' => 9,'16' => 9,'17' => 9,'18' => 9,'19' => 9);

$flag = 0;
foreach($str as $key=>$value)
{
   if($flag == $value)
   {
      unset($str[$key-1]);
   }
   $flag = $value;
 }
 echo "<pre>";
 print_r($str);
