我有两个数组$array1和$array2，它们是动态获得的，看起来像
$array1 = Array
(
[0] => Array
(
[hour] => 10
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 2
)
[1] => Array
(
[activity_id] => 2
[cnt] => 1
)
)
)
[1] => Array
(
[hour] => 11
[activity] => Array
(
)
)
[2] => Array
(
[hour] => 12
[percentage] => 0
[activity] => Array
(
[0] => Array
(
[activity_id] => 2
[cnt] => 5
)
[1] => Array
(
[activity_id] => 3
[cnt] => 2
)
)
)
);
$array2 = Array
(
[0] => Array
(
[id] => 1
[name] => Phone Calls
[readable] => 1
[status] => active
)
[1] => Array
(
[id] => 2
[name] => Meeting With Customer
[readable] => 1
[status] => active
)
[2] => Array
(
[id] => 3
[name] => Others Works
[readable] => 1
[status] => active
)
);
我需要比较一下。
如果$array2['id']不在$array1["activity"]中（即"activity_id"），则将数组['activity_id'=>$array2['id'],'cnt'=>0]添加到$array1['activity']。
我的结果一定像
$result = Array
(
[0] => Array
(
[hour] => 10
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 2
)
[1] => Array
(
[activity_id] => 2
[cnt] => 1
)
[2] => Array
(
[activity_id] => 3
[cnt] => 0
)
)
)
[1] => Array
(
[hour] => 11
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 0
)
[1] => Array
(
[activity_id] => 2
[cnt] => 0
)
[2] => Array
(
[activity_id] => 3
[cnt] => 0
)
)
)
[2] => Array
(
[hour] => 12
[percentage] => 0
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 0
)
[1] => Array
(
[activity_id] => 2
[cnt] => 5
)
[2] => Array
(
[activity_id] => 3
[cnt] => 2
)
)
)
);
我试过的是
$finalArray = array();
foreach($array1 as $arr1) {
foreach($array2 as $arr2) {
if(!in_array($arr2['id'], $arr1['activity'])) {
$array = ['activity_id'=>$arr2['id'], 'cnt'=>0];
}
array_push($arr1['activity'], $array);
unset($array);
}
array_push($finalArray, $result);
}
print_r($finalArray);
in_array()函数无法正常工作，或者我试图以错误的方式执行它。有人能帮我吗？
对不起，我终于明白我做错了什么。可能有人得到帮助。
一切都好，只要换一下
if(!in_array($arr2['id'], $arr1['activity'])) {
进入
if(!in_array( $readActivity['id'], array_column($result['activity'],'activity_id'))){
