Ds\Vector::sorted

(PECL ds >= 1.0.0)

Ds\Vector::sorted — Returns a sorted copy

public Ds\Vector::sorted(callable $comparator = ?): Ds\Vector

Returns a sorted copy, using an optional comparator function.

comparator: 在第一个参数小于，等于或大于第二个参数时，该比较函数必须相应地返回一个小于，等于或大于 0 的整数。

callback(mixed $a, mixed $b): int

警告
Returning non-integer values from the comparison function, such as float, will result in an internal cast to int of the callback's return value. So values such as 0.99 and 0.1 will both be cast to an integer value of 0, which will compare such values as equal.

Returns a sorted copy of the vector.

示例 #1 Ds\Vector::sorted() example


<?php
$vector = new \Ds\Vector([4, 5, 1, 3, 2]);

print_r($vector->sorted());
?>

以上例程的输出类似于：

Ds\Vector Object
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)

示例 #2 Ds\Vector::sorted() example using a comparator


<?php
$vector = new \Ds\Vector([4, 5, 1, 3, 2]);

$sorted = $vector->sorted(function($a, $b) {
    return $b <=> $a;
});

print_r($sorted);
?>

以上例程的输出类似于：

Ds\Vector Object
(
    [0] => 5
    [1] => 4
    [2] => 3
    [3] => 2
    [4] => 1
)
