cakephp 如何获取查询中的计数

Question

我正在使用此查询来获取所有数据，但我还需要在其中添加它返回的行数。

这是我的代码:

function getUsers($id){
    $users = $this->User->find('all', array('condition'=>array('my_id'=>$id)));
    $numUsers = sizeof($users);
    $users['User']['Total']= $numUsers;
    echo  json_encode($users);
}

$dArray包含用户的所有数据，但我也希望它告诉我有多少用户。

我在想我会在 User 对象中获取数据，但这就是我们给我的

Object
0: Object
1: Object
2: Object
3: Object
4: Object
5: Object
User: Object
Total: 6


instead of adding it to the 

0: Object
Company: Object
Group: Object
Team: Array[0]
User: Object
company_id: "20"
created: "2012-04-15 17:35:51"
email: "dd@gmail.com"
expiration_date: "2012-04-15 17:35:00"
firstname: "jason"
grants_id: null
group_id: "1"
id: "1"
lastname: "brawar"
modified: "2012-04-23 14:25:48"
name: null
password: "203e686b6a6938648ddd3eb0a8d95988ac638596"
phone: "abcd"
status: "Active"
type: null
username: "asim"
Total: 1

也许你正在寻找这个......

$conditions = array('somecondition' => $someCond);
$totalUsers = $this->User->find('count', array('conditions' => $conditions));

好的，现在如果要获取每个用户的元素总数，应该执行以下操作:

$users = $this->User->find('all');
foreach($users as $key => $user)
$ElementsForEachUser[$key]['totalRows'] = sizeof($user['User']);
