php拼接json的问题
要把数据库中的内容拼接成如下格式的json,请大神们用代码说明下

['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun','Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']

和这样格式的
 [{<br />            name: 'Tokyo',<br />            data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]<br />        }, {<br />            name: 'New York',<br />            data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]<br />        }]

我这样拼接时形成的json格式不对
hile($row2= sybase_fetch_array($result)){<br />		$arr[]=array($row2['outdate']);<br />}

拼出的格式多了"[]"
[["20140306"],["20140307"],["20140308"],["20140309"],["20140310"],["20140311"],["20140312"],["20140313"]] 


------解决方案--------------------
$arr[]=$row2['outdate'];
------解决方案--------------------
$arr[] = $row2['outdate'];

每个 array 是一对 []
