序列化不与Serializable接口工作

Question

class foo implements serializable 
    { 
    public function serialize() { 

      return serialize($this); 
     } 

     public function unserialize($serialized) 
     { 
      //Revive connection 
      AbstractContent::$connection= DatabaseHandle::getConnection(); 
      return unserialize($serialized); 
     } 
    }  


var_dump($this->object); //$this object is instance of class foo returns the exact dump of objects with correc property 

    var_dump(unserialize(serialize($this->object))); //Does not dump correctly. only default property values are evaluated, constructor assigned values are ignored, computed values are ignored 

Answer 1

由于每docs：

When the data is unserialized the class is known and the appropriate unserialize() method is called as a constructor instead of calling __construct(). If you need to execute the standard constructor you may do so in the method

而且，你没有做任何逻辑当使用serialize()时，您可以轻松覆盖_seelp() and __wakeup() magic methods而不是实施serializable。例如：

class foo 
{ 
    public function __wakeup() { 
     // Do your logic here 
    } 
} 
$foo = new foo(); 
var_dump(unserialize(serialize($foo))); 

Answer 2

class foo implements serilizable 

应该是：

class foo implements serializable 

只是一个简单的拼写错误
