我有一个看起来像这样的数组......
Array
(
[0] => Array
(
[code] => AS34
[2014-12-10] => 32
)
[1] => Array
(
[code] => AS34
[2014-12-11] => 42
)
[2] => Array
(
[code] => AS34
[2014-12-12] => 40
)
[3] => Array
(
[code] => AS34
[2014-12-15] => 44
)
[4] => Array
(
[code] => AH98
[2014-12-10] => 1
)
[5] => Array
(
[code] => AT78
[2014-12-12] => 1
)
[6] => Array
(
[code] => AL44
[2014-12-10] => 23
)
[7] => Array
(
[code] => AL44
[2014-12-11] => 27
)
[8] => Array
(
[code] => AL44
[2014-12-13] => 25
)
[9] => Array
(
[code] => AL44
[2014-12-15] => 26
)
)
我试图把它变成一个看起来像这样的数组......
var $example_data = array(
array(
'ID' => 1,
'code' => 'AS34',
'09/12/14' => '0',
'10/12/14' => '32',
'11/12/14' => '42',
'12/12/14' => '40',
'13/12/14' => '0',
'14/12/14' => '0',
'15/12/14' => '44',
),
array(
'ID' => 2,
'code' => 'AH98',
'09/12/14' => '0',
'10/12/14' => '1',
'11/12/14' => '0',
'12/12/14' => '0',
'13/12/14' => '0',
'14/12/14' => '0',
'15/12/14' => '0',
),
array(
'ID' => 3,
'code' => 'AT78',
'09/12/14' => '0',
'10/12/14' => '0',
'11/12/14' => '0',
'12/12/14' => '1',
'13/12/14' => '0',
'14/12/14' => '0',
'15/12/14' => '0',
),
array(
'ID' => 4,
'code' => 'AL44',
'09/12/14' => '0',
'10/12/14' => '23',
'11/12/14' => '27',
'12/12/14' => '0',
'13/12/14' => '25',
'14/12/14' => '0',
'15/12/14' => '26',
),
);
所以基本上它为每个代码设置一个数组＆＃39;然后是前7天。任何人都可以指向一个类似的例子的方向或者我正在考虑使用的正确方法的一些阅读吗？

像（固定）的东西：
$example_data = array();
foreach($data as $id => $row) {
$code = $row['code'];
unset($row['code']);
$karr = array_keys($row);
$date = current($karr);
$example_data[$code]['ID'] = $id;
$example_data[$code]['code'] = $code;
$example_data[$code][$date] = $row[$date];
}
print_r($example_data);

我想到了这个：
$data = Array
(
0 => Array
(
"id" => 1,
"code" => "AS34",
"2014-12-10" => 32
),
1 => Array
(
"id" => 1,
"code" => "AS34",
"2014-12-11" => 42
),
2 => Array
(
"id" => 1,
"code" => "AS34",
"2014-12-12" => 40
),
3 => Array
(
"id" => 1,
"code" => "AS34",
"2014-12-15" => 44
),
4 => Array
(
"id" => 1,
"code" => "AH98",
"2014-12-10" => 1
),
5 => Array
(
"id" => 1,
"code" => "AT78",
"2014-12-12" => 1
),
6 => Array
(
"id" => 1,
"code" => "AL44",
"2014-12-10" => 23
),
7 => Array
(
"id" => 1,
"code" => "AL44",
"2014-12-11" => 27
),
8 => Array
(
"id" => 1,
"code" => "AL44",
"2014-12-13" => 25
),
9 => Array
(
"id" => 1,
"code" => "AL44",
"2014-12-15" => 26
)
);
function in_array_r($needle, $haystack, $strict = false) { //taken from http://stackoverflow.com/a/4128377/4263082
foreach ($haystack as $item) {
if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict))) {
return true;
}
}
return false;
}
$codes = Array();
$counter = -1;
foreach($data as $key => $value) {
if(!in_array_r($data[$key]["code"], $codes, true)) {
$codes[++$counter] = Array();
foreach($data[$key] as $subkey => $subvalue) {$codes[$counter][$subkey] = $subvalue;}
}
else{
foreach($data[$key] as $subkey => $subvalue) {
if($subkey != "code" && $subkey != "id") {$codes[$counter][$subkey] = $subvalue;}
}
}
}
print_r($codes);
<强>输出
