Hi,
Without using traits, and the current implementation...
class A implements JSONSerializable
{
public $a = 1;
protected $d = 2;
private $c = 3;
// have to implement this in every class
function jsonSerialize()
{
return get_object_vars($this);
}
}
With using traits, don't have to provide an implementation
of jsonSerialize() unless want to customise the behaviour,
but the current implementation will require having to
implement JSONSerializable.
trait Json
{
function toJSONString() { return
json_encode($this->jsonSerialize()); }
function jsonSerialize() { return get_object_vars($this); }
}
class A implements JSONSerializable
{
use Json;
public $a = 1;
protected $d = 2;
private $c = 3;
}
class B implements JSONSerializable
{
use Json;
public $a = 1;
protected $d = 2;
private $c = 3;
function jsonSerialize()
{
return array('a' => $this->a, 'd' => 4);
}
}
$r = new array(new A(), new B(), );
echo json_encode($r), "\n";
But the JSONSerialiable interface doesn't really provide no
benefits over the trait, imo, so it could be eliminated
leaving...
trait Json
{
function toJSONString() { return
json_encode($this->jsonSerialize()); }
function jsonSerialize() { return get_object_vars($this); }
}
class A
{
use Json;
public $a = 1;
protected $d = 2;
private $c = 3;
}
class B
{
use Json;
public $a = 1;
protected $d = 2;
private $c = 3;
function jsonSerialize()
{
return array('a' => $this->a, 'd' => 4);
}
}
$r = new array(new A(), new B(), );
echo json_encode($r), "\n";
