The ArrayIterator::unserialize() function is an inbuilt function in PHP which is used to unserialize the serialize object.
Syntax:
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:
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"
}
}
Program 2:
<?php      // Declare an ArrayIterator $arrItr = new ArrayIterator(     array(         "a" => "Geeks",         "b" => "for",         "c" => "Geeks"    ) );   // Append some elements $arrItr->append("Computer"); $arrItr->append("Science"); $arrItr->append("Portal");       // Serialize the element $serialize = serialize($arrItr);   // Display the output var_dump($serialize);   // Unserialize the element $unserialize = unserialize($serialize);   // Display the output var_dump($unserialize);      ?> |
Output:
string(160) "C:13:"ArrayIterator":133:{x:i:0;a:6:{s:1:"a";s:5:"Geeks";
s:1:"b";s:3:"for";s:1:"c";s:5:"Geeks";i:0;s:8:"Computer";i:1;
s:7:"Science";i:2;s:6:"Portal";};m:a:0:{}}"
object(ArrayIterator)#2 (1) {
["storage":"ArrayIterator":private]=>
array(6) {
["a"]=>
string(5) "Geeks"
["b"]=>
string(3) "for"
["c"]=>
string(5) "Geeks"
[0]=>
string(8) "Computer"
[1]=>
string(7) "Science"
[2]=>
string(6) "Portal"
}
}
