Multidimensional array diff

Question

I got 2 arrays:

$big_array = array (
                    array (
                            array (
                                      \'correct\' => FALS         


        

Answer 1

yes you can use below function to get you perfect answer

function arrayRecursiveDiff($aArray1, $aArray2) {
  $aReturn = array();

  foreach ($aArray1 as $mKey => $mValue) {
    if (array_key_exists($mKey, $aArray2)) {
      if (is_array($mValue)) {
        $aRecursiveDiff = arrayRecursiveDiff($mValue, $aArray2[$mKey]);
        if (count($aRecursiveDiff)) { $aReturn[$mKey] = $aRecursiveDiff; }
      } else {
        if ($mValue != $aArray2[$mKey]) {
          $aReturn[$mKey] = $mValue;
        }
      }
    } else {
      $aReturn[$mKey] = $mValue;
    }
  }
  return $aReturn;
} 

  $arr1 =    arrayRecursiveDiff($big_array,$small_array);

output

as you need

Array

(
    [0] => Array
        (
            [1] => Array
                (
                    [correct] => 
                    [answer] => false answer2
                )

            [2] => Array
                (
                    [correct] => 
                    [answer] => false answer3
                )

            [3] => Array
                (
                    [correct] => 1
                    [answer] => correct answer
                )

        )
