Multidimensional array diff

Question

I got 2 arrays:

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


        

Answer 1

I just edited the function from Murali Kumar cause I needed one more information. It will check if the arrays are the same size and contains the same values.

function arrayRecursiveDiff($aArray1, $aArray2) {
    if(count($aArray1) > count($aArray2)) {
        $small_arr = $aArray2;
        $big_arr = $aArray1;
        $arr1_is_big = 1;
        $arr2_is_big = 0;
    } elseif(count($aArray1) < count($aArray2)) {
        $small_arr = $aArray1;
        $big_arr = $aArray2;
        $arr1_is_big = 0;
        $arr2_is_big = 1;
    } else {
        $small_arr = $aArray1;
        $big_arr = $aArray2;
        $arr1_is_big = 0;
        $arr2_is_big = 0;
    }
    $aReturn = array();

    foreach($big_arr as $mKey => $mValue) {
        if(array_key_exists($mKey, $small_arr)) {
            if(is_array($mValue)) {
                $aRecursiveDiff = arrayRecursiveDiff($mValue, $small_arr[$mKey]);
                if(count($aRecursiveDiff)) {
                    $aReturn[$mKey] = $aRecursiveDiff;
                }
            } else {
                if($mValue != $small_arr[$mKey]) {
                    $aReturn[$mKey] = $mValue;
                }
            }
        } else {
            $aReturn[$mKey] = $mValue;
        }
    }
    if($arr1_is_big)
        $aReturn["arr1_is_big"] = $arr1_is_big;

    if($arr2_is_big)
        $aReturn["arr2_is_big"] = $arr2_is_big;

    return ($aReturn);
}
