详解PHP序列化和反序列化原理

class fobnn
{
 public $hack_id;
 public $hack_name;
 public function __construct($name,$id)
 {
  $this->hack_name = $name;
  $this->hack_id = $id;
 }
 public function print()
 {
  var_dump($this->hack_name);
 }
}
$obj = new fobnn('fobnn',1);
$obj->print();
$serializedstr = serialize($obj);
echo $serializedstr.PHP_EOL;;
$toobj = unserialize($serializedstr);
$toobj->print();
$toobj2 = unserialize("O:5:\"fobnn\":2:{s:7:\"hack_id\";i:1;s:9:\"hack_name\";i:12345;}");
$toobj2->print();

string(5) "fobnn"
O:5:"fobnn":2:{s:7:"hack_id";i:1;s:9:"hack_name";s:5:"fobnn";}
string(5) "fobnn"
int(12345)
