我有一个带有一些键的数组,这里我需要的是在相同的键上合并值,例如,键117和&的记分卡值. 107应该在输出数组中合并如下所示.
$input_array = array (
38 => array
(
117 => array
(
'scorecard' => array
(
0 => 'q4'
),
'business_plan' => array
(
0 => 'q4'
)
),
107 => array
(
'scorecard' => array
(
0 => 'q1'
),
'business_plan' => array
(
0 => 'q2'
)
),
),
53 => array
(
373 => array
(
'scorecard' => array
(
0 => 'q4'
),
'business_plan' => array
(
0 => 'q1'
)
),
110 => array
(
'scorecard' => array
(
0 => 'q4',
0 => 'q3'
),
'business_plan' => array
(
0 => 'q4'
),
'marketing_plan' => array
(
0 => 'q3',
1 => 'q4'
)
)
),
318 => array
(
2279 => array
(
'scorecard' => array
(
0 => 'q4'
)
)
)
);
输出数组将包含如下值： –
Array
(
[38] => Array
(
[scorecard] => Array
(
[0] => q4
[1] => q1
)
[business_plan] => Array
(
[0] => q4
[1] => q2
)
)
[53] => Array
(
[scorecard] => Array
(
[0] => q4
[1] => q3
)
[business_plan] => Array
(
[0] => q1
[0] => q4
)
[marketing_plan] => Array
(
[0] => q3
[1] => q4
)
)
[318] => Array
(
[scorecard] => Array
(
[0] => q4
)
)
)
解决方法:
它可以通过组合array_map,array_reduce和array_merge_recursive来完成：
$result = array_map(function ($item) {
return array_reduce($item, 'array_merge_recursive', []);
}, $input_array);
这是working demo.
