php 數群組轉換json有問題 大家過來看看




為什麼下面這句話沒有輸出任何東西？

echo json_encode($result);#輸出結果

個人覺得可能是因為$data裡面的數組元素為Client對象，在轉為json的時候出問題了。但是我不知道是什麼問題，怎麼轉換？或者有沒有其他的轉換方法？

class Result {
var $state;
var $data = array();
}

完整代碼：

$start = 0;
$end = 2;
$uid = 1;
$result = new Result();
$result_set = getClients($start, $end, $uid);
$data = array();
$count = 0;

while($row = mysql_fetch_array($result_set)) {
$client = new Client();
$client->cid = $row['id'];
$client->gender = $row['gender'];
$client->rank = $row['rank'];
$client->name = $row['name'];
$client->phoneNum = $row['phoneNum'];
$client->email = $row['email'];
$client->address = $row['address'];
$result->data[$count] = $client;

echo $result->data[$count]->cid."  ";
echo $result->data[$count]->gender."  ";
echo $result->data[$count]->rank."  ";
echo $result->data[$count]->name."  ";
echo $result->data[$count]->phoneNum."  ";
echo $result->data[$count]->address."\n";

$count++;
    }

if(count($data) > 0) {
$result->state = 0;
} else {
$result->state = 1;
}

echo json_encode($result);#輸出結果

class Result {
var $state;
var $data = array();
}

輸出結果：

應該有輸出類似這種格式才對的：

{"state":1,
"data":[
           {"cid":3,
          "gender":0,
          "rank":"經理"
          "name":" 張小莉"
          "phoneNum":"18825044888  "
          "address":"廣東省廣州市天河區"},
          {"cid":4,
          "gender":0,
          "rank":"主管"
          "name":" 吳美鳳"
          "phoneNum":"18576430777  "
          "address":" 廣東省深圳市南山區蛇口南海大道1079號"}
          ]
}

請問這是什麼問題呢？怎麼解決？謝謝！





------解決思路----------------------
print_r($result);
能看到什嗎？
------解決思路----------------------
Object of class Result could not be converted to string 對象不能被轉換為字串
既如此，當然也不能 json 了
看看你的 Client 類定義
------解決思路----------------------
可能沒有值吧
