Question

假设，我有一个数组

$my_array = array(
    array(
        array('cnt' => 1, 'date' => '2016-06-18', 'name' => 'Phone Calls'),
        array('cnt' => 1,'date' => '2016-06-18','name' => 'Others Works')
    ),
    array(
        array('cnt' => 2 , 'date' => '2016-06-17', 'name' => 'Phone Calls'),
        array('cnt' => 1, 'date' => '2016-06-17', 'name' => 'Others Works'),
        array('cnt' => 1, 'date' => '2016-06-17', 'name' => 'Deal with Customer')
    ),
     array(
        array('cnt' => 4 , 'date' => '2016-06-15', 'name' => 'Phone Calls'),
        array('cnt' => 5, 'date' => '2016-06-15', 'name' => 'Others Works'),
        array('cnt' => 6, 'date' => '2016-06-15', 'name' => 'Deal with Customer')
    )
   .....
);

我需要转换成

$desired_result = array(
    array('date' => '2016-06-18', 
         'Phone Calls' => 1,//value is cnt of my_array
         'Others Works' => 1,//value is cnt of my_array
    ),
    array('date' => '2016-06-17', 
        'Phone Calls' => 2,//value is cnt of my_array
        'Others Works' => 1,//value is cnt of my_array
        'Deal with Customer' => 1,   
    ),
    array('date' => '2016-06-15', 
        'Phone Calls' => 4,//value is cnt of my_array
        'Others Works' => 5,//value is cnt of my_array
        'Deal with Customer' => 6,   
    )
    .......
);

我需要按数组对数组进行分组，其中数组名称与key相同，cnt为value。任何人都可以建议我如何格式化此数组。

我想试试http://bl.ocks.org/katirg/5f168b5c884b1f9c36a5。

我是d3js的新手，所以我想我会更好地格式化我的数组。

您需要循环外部数组，然后循环每个数组。获取索引名称并在值为该数组cnt。

的新数组中创建索引

$my_array = array(
    array(
        array('cnt' => 1, 'date' => '2016-06-18', 'name' => 'Phone Calls'),
        array('cnt' => 1,'date' => '2016-06-18','name' => 'Others Works')
    ),
    array(
        array('cnt' => 2 , 'date' => '2016-06-17', 'name' => 'Phone Calls'),
        array('cnt' => 1, 'date' => '2016-06-17', 'name' => 'Others Works'),
        array('cnt' => 1, 'date' => '2016-06-17', 'name' => 'Deal with Customer')
    ),
    array(
        array('cnt' => 4 , 'date' => '2016-06-15', 'name' => 'Phone Calls'),
        array('cnt' => 5, 'date' => '2016-06-15', 'name' => 'Others Works'),
        array('cnt' => 6, 'date' => '2016-06-15', 'name' => 'Deal with Customer')
    )
);

$betterFormat = array();
foreach($my_array as $arrays){
    $newArray = array();

    //Assume the date is the same in both arrays
    $newArray['date'] = $arrays[0]['date'];

    foreach($arrays as $arr){
      $newArray[$arr['name']] = $arr['cnt'];
    }

    $betterFormat[] = $newArray;
}
echo "<pre>";
var_dump($betterFormat);

输出

array(3) {
    [0]=> array(3) {
        ["date"]=> string(10) "2016-06-18"
        ["Phone Calls"]=> int(1)
        ["Others Works"]=> int(1)
    }
    [1]=> array(4) {
        ["date"]=> string(10) "2016-06-17"
        ["Phone Calls"]=> int(2)
        ["Others Works"]=>int(1)
        ["Deal with Customer"]=> int(1)
    }
    [2]=> array(4) {
        ["date"]=> string(10) "2016-06-15"
        ["Phone Calls"]=> int(4)
        ["Others Works"]=> int(5)
        ["Deal with Customer"]=> int(6)
    }
}

使用键值重新排列数组
