如何从两个阿雷

Question

删除重复的元素这是我的数组

(
    "userServiceIds": "1,2,3", 
    "enggServiceIds": "4,5,6,2,1" 
) 

为"userServiceIds"有交叉与"enggServiceIds"检查和"enggServiceIds"有过与"userServiceIds"

为OUTPUT检查只需要

"userServiceIds": "1,2,3" 
"enggServiceIds": "4,5,6" 

Answer 1

也许您在寻找array_diff。

$data = [ 
    'userServiceIds' => [1,2,3], 
    'enggServiceIds' => [4,5,6,2,1] 
]; 

$data['enggServiceIds'] = array_diff($data['enggServiceIds'], $data['userServiceIds']);
