Below programs illustrate the SplDoublyLinkedList::serialize() function in PHP:

Program 1:

<?php 
  
// Declare an empty SplDoublyLinkedList  
$list = new SplDoublyLinkedList(); 
  
// Use SplDoublyLinkedList::push() function to   
// add elements to the SplDoublyLinkedList  
$list->push(1);  
$list->push(2);  
$list->push(3);  
$list->push(8);  
$list->push(5);  
  
// Use serialize() function 
$serialize = serialize($list); 
  
echo $serialize; 
?> 

Output:

C:19:"SplDoublyLinkedList":29:{i:0;:i:1;:i:2;:i:3;:i:8;:i:5;}

Program 2:

<?php 
  
// Declare an empty SplDoublyLinkedList  
$list = new SplDoublyLinkedList(); 
  
// Use SplDoublyLinkedList::add() function 
// to add the element into the list 
$list->add(0, "Welcome");  
$list->add(1, "to");  
$list->add(2, "GeeksforGeeks");  
$list->add(3, "A");  
$list->add(4, 'Computer');  
$list->add(5, "Science");  
$list->add(6, 'Portal');  
  
// Use serialize() function 
$serialize = serialize($list); 
  
echo $serialize; 
?> 

Output:

C:19:"SplDoublyLinkedList":105:{i:0;:s:7:"Welcome";:s:2:
"to";:s:13:"GeeksforGeeks";:s:1:"A";:s:8:"Computer";
:s:7:"Science";:s:6:"Portal";}
