Ds\Deque::sorted

(PECL ds >= 1.0.0)

Ds\Deque::sorted — Returns a sorted copy.

public Ds\Deque Ds\Deque::sorted ([ callable $comparator ] )

Returns a sorted copy, using an optional comparator function.

comparator: Funcția de comparare trebuie să întoarcă un întreg mai mic, egal cu sau mai mare decât zero dacă primul argument este considerat respectiv mai mic, egal cu sau mai mare decât al doilea argument.

int callback ( mixed $a, mixed $b )

Precauţie
Returning non-integer values from the comparison function, such as float, will result in an internal cast to integer 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 deque.

Example #1 Ds\Deque::sorted() example


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

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

Exemplul de mai sus va afișa ceva similar cu:

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

Example #2 Ds\Deque::sorted() example using a comparator


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

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

print_r($sorted);
?>

Exemplul de mai sus va afișa ceva similar cu:

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