I get two arrays
But I need them to be merged, values that are equal are removed: in
array_unique( array_merge($array1, $array2) )
You can remove the duplicates, but I want to remove both duplicates.
Is there a simple method, or is it even looping?
You can remove duplicate and singular items by making the difference in arrays twice as much as $a with $b and $b with $a .
The first call of array_diff() returns the elements: 3, 30 and 40 and the second: 70 and 80
$a1 = array(1, 2, 3, 5, 30, 40,99);
$a2 = array(1, 2, 5, 80, 70, 99);
$n = array_merge(array_diff($a1, $a2) , array_diff($a2, $a1));
echo "<pre>";
print_r($n);
Output:
Array
(
[0] => 3
[1] => 30
[2] => 40
[3] => 80
[4] => 70
)
You can use array_intersect and update the old arrays:
$array_antes = array_intersect($array_antes, $array_concatenado);
