I was asked to provide the solution of this rolling dice problem in an interview. When I showed him my solution, he said that there is another way to find the solution. I am looking for answer in PHP script only.Question:Two persons are playing a game of rolling 2 dices. Each person rolls the two dices n times and records the outcomes (sum of value of two dices) of all the n attempts. So after n attempts of both the player we have two list corresponding to the n outcomes of two players. They want to know that whether they have got all possible outcomes( 1 to 12) same number of times or not. If they got all the possible outcomes same number of times then they are called lucky otherwise unlucky.Input: Two Integer Arrays (L1, L2) corresponding to outcomes of two players.Output: Lucky or Unlucky depending on the caseMy Answer:<?phpfunction rollingdice($input1,$input2){  foreach($input1 as $k=>$a)  {     if(in_array($a,$input2))    {$p = array_search($a, $input2);     unset($input2[$p]);    }    else    { return 'Unlucky';}  }return 'Lucky';}?>

Based on your use of in_array(), you don't appear to be concerned with the order of the elements. In that case, you can simply sort the arrays and compare them directly.function compare($array1, $array2){    sort($array1);    sort($array2);    return ($array1 == $array2) ? Lucky : Unlucky;}
