Parameter: This function accepts single parameter $values which holds the elements.

Return Value: This function returns the sequence adding all the elements.

Below programs illustrate the Ds\Sequence::merge() function in PHP:



Program 1:




<?php
   
// Create new sequence
$seq new \Ds\Vector([12, 15, 18, 20]);
  
// Merge the sequence and display it
var_dump($seq->merge([1, 2, 3]));
  
// Display the sequence element
var_dump($seq)
?>

Output:

object(Ds\Vector)#2 (7) {
  [0]=>
  int(12)
  [1]=>
  int(15)
  [2]=>
  int(18)
  [3]=>
  int(20)
  [4]=>
  int(1)
  [5]=>
  int(2)
  [6]=>
  int(3)
}
object(Ds\Vector)#1 (4) {
  [0]=>
  int(12)
  [1]=>
  int(15)
  [2]=>
  int(18)
  [3]=>
  int(20)
}

Program 2:




<?php
   
// Create new sequence
$seq new \Ds\Vector([12, 15, 18, 20]);
  
// Merge the sequence and display it
var_dump($seq->merge(["G", "E", "E", "k", "S"]));
  
?>

Output:

object(Ds\Vector)#2 (9) {
  [0]=>
  int(12)
  [1]=>
  int(15)
  [2]=>
  int(18)
  [3]=>
  int(20)
