The Ds\Sequence::push() function is an inbuilt function in PHP which adds values to the end of the sequence. Syntax:

void abstract public Ds\Sequence::push( $values )

Parameters: This function accepts single parameter $values which contains one or more values. It hold the value to be added in the sequence. Return value: This function does not return any value. Below programs illustrate the Ds\Sequence::push() function in PHP: Program 1:

<?php
 
// Create new sequence
$seq =  new \Ds\Vector([12, 15, 18, 20]);

// Use push() function to add
// element in the sequence
$seq->push(24);

// Use push() function to add
// element in the sequence
$seq->push("S");

// Use push() function to add
// element in the sequence
$seq->push("Geeks");

// Use push() function to add
// element in the sequence
$seq->push(2);

var_dump($seq);
?>

Output:

object(Ds\Vector)#1 (8) {
  [0]=>
  int(12)
  [1]=>
  int(15)
  [2]=>
  int(18)
  [3]=>
  int(20)
  [4]=>
  int(24)
  [5]=>
  string(1) "S"
  [6]=>
  string(5) "Geeks"
  [7]=>
  int(2)
}

Program 2:

<?php
 
// Create new sequence
$seq =  new \Ds\Vector([12, 15, 18, 20]);

$arr = array ("g", "e", "e", "k");

// Loop run for every array element  
foreach ($arr as $val) {  

    // Use push() function to add
    // element in the sequence
    $seq->push($val);
}

var_dump($seq);
?>

Output:

object(Ds\Vector)#1 (8) {
  [0]=>
  int(12)
  [1]=>
  int(15)
  [2]=>
  int(18)
  [3]=>
  int(20)
  [4]=>
  string(1) "g"
  [5]=>
