我可以寻求一些帮助吗？我不知道如何实现这一点。我有3个数组。我想把它们合并为一个，我还想对特定user_id的outrange、internal和overdiff求和。
预期的输出数组类似于
user_id => 39,
full_name => Mila Doe,
outrange =>20,
inside=>30,
overdiff=>50
提前谢谢。
//阵列1

你应该试试这样的方法。
<?php
$arrays = array($array1, $array2, $array3);
//result will be a map : key = user_id, value = information and sums
$result = array();
//go through each array
foreach ($arrays as $array) {
//go through each data of each array
foreach ($array as $userData) {
//first time we see data about this user ?
if (!isset($result[$userData['user_id']])) {
$result[$userData['user_id']] = array();
}
//set or sum informations of this user in the result array.
$result[$userData['user_id']]['user_id'] = $userData['user_id'];
$result[$userData['user_id']]['full_name'] = $userData['full_name'];
if (isset($userData['outrange'])) {
$result[$userData['user_id']]['outrange'] += $userData['outrange'];
}
if (isset($userData['inside'])) {
$result[$userData['user_id']]['inside'] += $userData['inside'];
}
if (isset($userData['overdiff'])) {
$result[$userData['user_id']]['overdiff'] += $userData['overdiff'];
}
}
}
$result = array_values($result);
