Ds\Sequence::sorted

(PECL ds >= 1.0.0)

Ds\Sequence::sorted — Returns a sorted copy

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

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.

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

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 sequence.

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


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

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

Exemplul de mai sus va afișa ceva similar cu:

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

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


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

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

print_r($sorted);
?>

Exemplul de mai sus va afișa ceva similar cu:

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