PHP | Ds\Vector sorted() Function

Last Updated : 22 Aug, 2019

The Ds\Vector::sorted() function is an inbuilt function in PHP which is used to sort the elements of the vector by creating a copy of the original vector. This will arrange the vector elements in increasing order using default comparator. Syntax:

Ds\Vector public Ds\Vector::sorted( $comparator )

Parameters: This function accepts single parameter $comparator which holds the sorting function. Return Value: This function returns a copy of sorted vector. Below programs illustrate the Ds\Vector::sorted() function in PHP: Program 1:

PHP

<?php

// Declare new Vector
$vect = new \Ds\Vector([6, 5, 4, 3, 2, 1]);

echo("Original vector\n");

// Display the vector elements
var_dump($vect);

// Use sorted() function to sort
// the copy of vector elements
$res = $vect->sorted();

echo("\nSorted elements\n");

// Display the sorted elements
var_dump($res);

?>

Output:

Original vector
object(Ds\Vector)#1 (6) {
  [0]=>
  int(6)
  [1]=>
  int(5)
  [2]=>
  int(4)
  [3]=>
  int(3)
  [4]=>
  int(2)
  [5]=>
  int(1)
}

Sorted elements
object(Ds\Vector)#2 (6) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(4)
  [4]=>
  int(5)
  [5]=>
  int(6)
}

Program 2:

PHP

<?php

// Declare new Vector
$vect = new \Ds\Vector([3, 6, 1, 2, 9, 7]);

echo("Original vector\n");

// Display the vector elements
var_dump($vect);

// Use sorted() function to sort
// the copy of vector elements
$res = $arr->sorted(function($element1, $element2) {
    return $element1 <=> $element2;
});

echo("\nSorted elements\n");

// Display the sorted elements
var_dump($res);

?>

Output:

Original vector
object(Ds\Vector)#1 (6) {
  [0]=>
  int(3)
  [1]=>
  int(6)
  [2]=>
  int(1)
  [3]=>
  int(2)
  [4]=>
  int(9)
  [5]=>
  int(7)
}

Sorted elements
object(Ds\Vector)#3 (6) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(6)
  [4]=>
  int(7)
  [5]=>
  int(9)
}
