问题描述
我想了解两个多维项目之间的区别，例如，
I want to get the difference of two multidimensional arrys, e.g.,
第一个数组:
Array
(
[qtr_selected] => Array
(
[partner_q_m_p__2031] => Array
(
[0] => q1
[1] => q2
)
[partner_q_m_p__2032] => Array
(
[0] => q1
)
)
)
第二个数组:
Array
(
[qtr_completed] => Array
(
[partner_q_m_p__2031] => Array
(
[0] => q1
)
)
)
我如何获得array1&的区别? array2如下所示:
how do i get the difference of array1 & array2 as given below:
Array
(
[qtr_final] => Array
(
[partner_q_m_p__2031] => Array
(
[0] => q2
)
[partner_q_m_p__2032] => Array
(
[0] => q1
)
)
)
尝试使用array_diff()函数，但未将array1作为除array2之外的其他变量，我希望从中减去array2后再获得array1.
Tried array_diff() function but not getting array1 as difference except array2, i want array1 after subtracting array2 from it.
推荐答案
只需创建一个自定义函数，如
Simply make a custom function like as
function check_diff($arr1, $arr2){
$check = (is_array($arr1) && count($arr1)>0) ? true : false;
$result = ($check) ? ((is_array($arr2) && count($arr2) > 0) ? $arr2 : array()) : array();
if($check){
foreach($arr1 as $key => $value){
if(isset($result[$key])){
$result[$key] = array_diff($value,$result[$key]);
}else{
$result[$key] = $value;
}
}
}
return $result;
}
$result['qtr_final'] = check_diff($a1['qtr_selected'],$a2['qtr_completed']);
print_r($result);
