function SplDoublyLinkedList::offsetSet()in PHP:
Program 1:
// Declare an empty SplDoublyLinkedList $list = ne w SplDoublyLinkedList;
// Use the SplDoublyLinkedList::add() function for
// add elements to SplDoublyLinkedList $list -> add (0, 30); $list -> add (1, 20); $list -> add (2, 30); $list -> add (3, " Geeks " ); $list -> add (4, ’ G’ ); $list -> rewind ();
// Use the SplDoublyLinkedList::offsetSet() function
// set the value to the specified index $list -> offsetSet (1, " GeeksforGeeks " ); $list -> offsetSet (2, " Welcome " ); var_dump ( $list );
?> Exit:object (SplDoublyLinkedList ) # 1 (2) {["flags": "SplDoublyLinkedList": private] = > int (0) ["dllist": "SplDoublyLinkedList": private] = > array (5) {[0] = > int (30) [1] = > string (13) "GeeksforGeeks" [2] = > string (7) "Welcome" [3] = > string (5) "Geeks" [4] = > string (1) "G"}} Program 2:
// Declare an empty SplDoublyLinkedList $list = new SplDoublyLinkedList ( );
// Use the SplDoublyLinkedList::push() function for
// add elements to SplDoublyLinkedList $list -> push (1); $list -> push (2); $list -> push (3); $list -> push (8); $list -> push (5);

// set the value to the specified index $list -> offsetSet (1, " Welcome " ); $list -> offsetSet (2, " to " ); $list -> offsetSet (3, " GeeksforGeeks " ); print_r ( $list );
?> Exit:SplDoublyLinkedList Object ( [flags: SplDoublyLinkedList: private] = > 0 [dllist: SplDoublyLinkedList: private] = > Array ([0] = > 1 [1] = > Welcome [2] = > to [3] = > GeeksforGeeks [4] = > 5))
