json_decode数据丢失

我有一个JSON字符串(外部文件),其元素可以是FALSE或TRUE作为值。在文件中,那里是真或假。但是,在我使用json_decode之后,会丢失true或false。为什么呢?

JSON是有效的,它是由许多

块构成的
{
   "surroundedDebuff":true,
   "citizenId":108981,
   "citizenship":19,
   "berserk":true,
   "defenderSide":false,
   "weapon":0,
   "time":"25-03-2012 16:07:13:442",
   "damage":65
}

(这反复多次),检查是一个简单的print_r。

print_r不显示类型,因此它将显示0表示false,1表示true。 var_dump会显示这些值实际上是布尔值。

$decoded = json_decode('{"surroundedDebuff":true,"citizenId":108981,"citizenship":19,"berserk":true,"defenderSide":false,"weapon":0,"time":"25-03-2012 16:07:13:442","damage":65}');

print_r($decoded);
var_dump($decoded);

输出:

stdClass Object
(
    [surroundedDebuff] => 1
    [citizenId] => 108981
    [citizenship] => 19
    [berserk] => 1
    [defenderSide] => 
    [weapon] => 0
    [time] => 25-03-2012 16:07:13:442
    [damage] => 65
)
object(stdClass)#1 (8) {
  ["surroundedDebuff"]=>
  bool(true)
  ["citizenId"]=>
  int(108981)
  ["citizenship"]=>
  int(19)
  ["berserk"]=>
  bool(true)
  ["defenderSide"]=>
  bool(false)
  ["weapon"]=>
  int(0)
  ["time"]=>
  string(23) "25-03-2012 16:07:13:442"
  ["damage"]=>
  int(65)
}
