PHP | ArrayIterator unserialize()函数

ArrayIterator::unserialize()函数是PHP中的一个内置函数,用于反序列化序列化对象。

句法:

void ArrayIterator::unserialize( string $serialized )

参数:此函数接受单个参数$serialized ,其中包含序列化数组迭代器对象。

返回值:该函数返回未序列化对象的序列化ArrayIterator对象。

下面的程序说明了PHP中的 ArrayIterator::unserialize()函数:

方案一:


输出:
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"
  }
}

方案二:

 "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);
     
?>
输出:
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"
  }
}
