Remove array items with nonsense value to reduce the size.

2.3.2

drop(iterable $array, callable $fn = null);

Example:

$array = [0, 1, 'a', "", true, false, null, [], [0, 1, 'a', ""]];

$A = drop($array);
$B = drop($array, function($v) {
    return 'a' === $v;
});

Result:

$A = [
    0 => 0,
    1 => 1,
    2 => 'a',
    4 => true,
    5 => false,
    8 => [
        0 => 0,
        1 => 1,
        2 => 'a'
    ]
];

$B = [
    0 => 0,
    1 => 1,
    3 => "",
    4 => true,
    5 => false,
    6 => null,
    7 => []
    8 => [
        0 => 0,
        1 => 1,
        3 => ""
    ]
];
