按照PHP的序列化協(xié)議
此方法最大的優(yōu)勢(shì)，可以將“對(duì)象完整保存”
class Person{
private $age;
public function __construct($age)
{
$this->age=$age;
}
public function sayAge(){
return $this->age;
}
}
$p1=new Person(100);
$s=serialize($p1);
$p2=unserialize($s);
echo $p2->sayAge(),PHP_EOL;
按照json格式
- 此方法不能將方法宏悦，私用的屬性進(jìn)行序列化镐确。
- 最佳實(shí)踐，使用stdClass對(duì)象即可饼煞，并不需要型別信息源葫。
class Human{
public $name='john';
private $age=100;
public $favs=['bas','swim'];
public $addrs=[];
public function __construct()
{
$a1=new stdClass();
$a1->tel='123';
$a2=new stdClass();
$a2->tel='456';
array_push($this->addrs,$a1);
array_push($this->addrs,$a2);
}
}
$h1=new Human;
//序列化
$rs=json_encode($h1);
echo $rs,PHP_EOL;
//反序列化
$obj=json_decode($rs);//$obj是一個(gè)stdClass對(duì)象
print_r($obj);
結(jié)果如下：
{"name":"john","favs":["bas","swim"],"addrs":[{"tel":"123"},{"tel":"456"}]}
stdClass Object
(
[name] => john
[favs] => Array
(
[0] => bas
[1] => swim
)
[addrs] => Array
(
[0] => stdClass Object
(
[tel] => 123
)
[1] => stdClass Object
(
[tel] => 456
)
)
)
