a comparison is being made:

this way

$result3 = array_diff($fetchForm, $items['form_id']);
print_r($result3);

    Array
    (
        [0] => 1
        [2] => 3
    )

$result2 = array_diff($items['form_id'], $fetchForm);
print_r($result2);

    Array
    (
        [1] => 4
    )

so that way

Array
(
    [0] => 1
    [1] => 3
)

Array
(
    [0] => 4
)

    I don’t understand the question. And these arrays that you showed, are the diff input?

  • these arrays are the exits

  • 2

    What do you mean "the" exits? array_diff returns one array. And what would be the entries then?

    It seems to me that we missed the clear question. Edit there and try to explain better to try to help.

  • lost yes... but this and another part more the front Kela part I could not solve for now I am developing this one then you will return there you will publish it to see if you can give me a hand

  • then are two inputs so 2 array... actually and 1 input just there matches the database there separates into 2 array

  • You have 2 array_diff?

  • 1

    yes... I edited it... the diff is the opposite of the other

Array-diff, returns an array containing all array1 entries that are not present in any of the other arrays.

Array-diff will return to KEY and VALUE, for this reason you do not receive an array with ordered indices.

$array1 = array("verde", "vermelho", "azul", "amarelo");
$array2 = array("verde", "vermelho");
$result = array_diff($array1, $array2);

output: array( 2 => 'azul' , 3 => 'amarelo' )

To redo your array in order, you can use array_values

$result = array_values( $result );
print_r($result);

output: array( 0 => 'azul' , 1 => 'amarelo' )
