这是我放在一起的数组:
Array
(
[1] => Array
(
[0] => Array
(
[date] => 1335848400000
[value] => 1
[product_id] => 1
[title] => Test Product
)
[1] => Array
(
[date] => 1338526800000
[value] => 8
[product_id] => 1
[title] => Test Product
)
)
[2] => Array
(
[0] => Array
(
[date] => 1335848400000
[value] => 1
[product_id] => 2
[title] => Test Product 2
)
[1] => Array
(
[date] => 1338526800000
[value] => 4
[product_id] => 2
[title] => Test Product 2
)
)
[3] => Array
(
[0] => Array
(
[date] => 1338526800000
[value] => 6
[product_id] => 3
[title] => Test Product 3
)
)
)
我希望它显示为:
{
name: 'Test Product',
data: [[1335848400000, 1],[1338526800000, 8]]
},
{
name: 'Test Product 2',
data: [[1335848400000, 1], [1338526800000, 4]]
},
{
name: 'Test Product 3',
data: [[1338526800000, 6]]
},
对于highcharts,我需要按日期和值分组。
我该怎么做呢?我什至不知道从哪里开始。我已经对其进行了研究,但找不到一个很好的例子。
编辑:
工作代码,除了一个错误:
for($i=0 ; $i<=count($array) ; $i++)
{
$result_array[$i]['name'] = $array[$i][0]['title'];
for($j=0 ; $j<count($array[$i]) ; $j++)
{
$result_array[$i]['data'][$j][0] = $array[$i][$j]['date'];
$result_array[$i]['data'][$j][1] = $array[$i][$j]['value'];
}
}
echo $result = json_encode($result_array);
错误:
