Syntax:
php
php
void ArrayIterator::unserialize( string $serialized )Parameters: This function accepts single parameter $serialized which holds the serialize array iterator object. Return Value: This function returns the serialized ArrayIterator object of unserialized object. Below programs illustrate the ArrayIterator::unserialize() function in PHP: Program 1:
<?php
// Declare an ArrayIterator
$arrItr = new ArrayIterator(
array('G', 'e', 'e', 'k', 's')
);
// Serialize the element
$serialize = serialize($arrItr);
// Display the output
var_dump($serialize);
// Unserialize the serialize element
$unserialize = unserialize($serialize);
// Display the result
var_dump($unserialize);
?>
Output:
Program 2:
string(107) "C:13:"ArrayIterator":81:{x:i:0;a:5:{i:0;s:1:"G";i:1;
s:1:"e";i:2;s:1:"e";i:3;s:1:"k";i:4;s:1:"s";};m:a:0:{}}"
object(ArrayIterator)#2 (1) {
["storage":"ArrayIterator":private]=>
array(5) {
[0]=>
string(1) "G"
[1]=>
string(1) "e"
[2]=>
string(1) "e"
[3]=>
string(1) "k"
[4]=>
string(1) "s"

"b" => "for",
"c" => "Geeks"
)
);
// Append some elements
$arrItr->append("Computer");
$arrItr->append("Science");
$arrItr->append("Portal");

// Unserialize the element
$unserialize = unserialize($serialize);
// Display the output
var_dump($unserialize);
