如何使用array_slice返回包含已删除元素而不是数组的数组

Question

function take()
{
$array = [1, 2, 3];
return array_slice($array, 2);
}

So this function returns with an array containing 3, but i'd like to return with an array containing 1 and 2, is this possible somehow?

Answer 1

If you want to return the the remaining part of the array, use array_diff.

function take()
{
   $array = [1, 2, 3];
   return array_diff ($array, array_slice($array, 2));
}
