PHP Laravel 检查两个数组和未设置的值

Question

嗨，我正在做一个项目，我可以将一些状态分配给 project，这些状态保存在表 assigned_statuses 中。现在我使用 jquery 连接列表来决定用户如何分配它们。因此，当我加载这两个列表时，一个将填充已分配的列表，另一个将填充可用的列表。 要获取分配的模型，我有以下模型函数：

app/models/AssignedStatus.php

public function projects() {
    return $this->belongsTo('Project');
}
public function statuses() {
    return $this->belongsTo('Status');
}

app/models/Project.php

public function assignedProjectBoardStatuses() {
        return $this->hasMany('AssignedProjectBoardStatus','project_id')->orderBy('order','asc');
    }

app/models/Status.php

public function assignedProjectBoardStatus() {
        return $this->hasMany('AssignedProjectBoardStatus');
}

我呼吁如下：

$project = Project::with(['assignedStatuses', 'assignedStatuses.statuses'])->find($id);

我抓取的状态如下：

$statuses = Status::statusByOrder();

现在返回一个数组如下：

$project数组：

array(12) {
["id"]=>
string(1) "3"
["name"]=>
string(11) "Project 13"
["start_date"]=>
string(10) "2015-07-13"
["end_date"]=>
string(10) "2015-07-27"
["active"]=>
string(1) "0"
["cancelled"]=>
string(1) "0"
["archive"]=>
string(1) "0"
["deleted_at"]=>
NULL
["created_at"]=>
string(19) "2015-07-26 00:01:59"
["updated_at"]=>
string(19) "2015-07-26 00:01:59"
["assigned_statuses"]=>
array(4) {
[0]=>
array(7) {
["id"]=>
string(1) "1"
["project_id"]=>
string(1) "3"
["status_id"]=>
string(1) "1"
["order"]=>
string(1) "0"
["created_at"]=>
string(19) "2015-07-26 00:01:59"
["updated_at"]=>
string(19) "2015-07-26 00:01:59"
["statuses"]=>
array(8) {
["id"]=>
string(1) "1"
["name"]=>
string(7) "Backlog"
["order"]=>
string(1) "0"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:03"
}
}
[1]=>
array(7) {
["id"]=>
string(1) "2"
["project_id"]=>
string(1) "3"
["status_id"]=>
string(1) "3"
["order"]=>
string(1) "1"
["created_at"]=>
string(19) "2015-07-26 00:02:00"
["updated_at"]=>
string(19) "2015-07-26 00:02:00"
["statuses"]=>
array(8) {
["id"]=>
string(1) "3"
["name"]=>
string(11) "In Progress"
["order"]=>
string(1) "1"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:04"
}
}
[2]=>
array(7) {
["id"]=>
string(1) "3"
["project_id"]=>
string(1) "3"
["status_id"]=>
string(1) "4"
["order"]=>
string(1) "2"
["created_at"]=>
string(19) "2015-07-26 00:02:00"
["updated_at"]=>
string(19) "2015-07-26 00:02:00"
["statuses"]=>
array(8) {
["id"]=>
string(1) "4"
["name"]=>
string(6) "Review"
["order"]=>
string(1) "2"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:05"
}
}
[3]=>
array(7) {
["id"]=>
string(1) "4"
["project_id"]=>
string(1) "3"
["status_id"]=>
string(1) "5"
["order"]=>
string(1) "3"
["created_at"]=>
string(19) "2015-07-26 00:02:00"
["updated_at"]=>
string(19) "2015-07-26 00:02:00"
["statuses"]=>
array(8) {
["id"]=>
string(1) "5"
["name"]=>
string(4) "Done"
["order"]=>
string(1) "3"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:08"
}
}
}
}

还有statuses 数组：

array(5) {
[0]=>
array(8) {
["id"]=>
string(1) "1"
["name"]=>
string(7) "Backlog"
["order"]=>
string(1) "0"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:03"
}
[1]=>
array(8) {
["id"]=>
string(1) "3"
["name"]=>
string(11) "In Progress"
["order"]=>
string(1) "1"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:04"
}
[2]=>
array(8) {
["id"]=>
string(1) "4"
["name"]=>
string(6) "Review"
["order"]=>
string(1) "2"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:05"
}
[3]=>
array(8) {
["id"]=>
string(1) "5"
["name"]=>
string(4) "Done"
["order"]=>
string(1) "3"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:08"
}
[4]=>
array(8) {
["id"]=>
string(1) "2"
["name"]=>
string(4) "Open"
["order"]=>
string(1) "4"
["created_at"]=>
string(19) "2015-07-25 23:22:54"
["updated_at"]=>
string(19) "2015-07-25 23:23:01"
}
}

这就是我目前所拥有的：

    if(array_key_exists('assigned_statuses', $project)) {
        foreach ($project->assigned_statuses as $status) {
            $assignedIds [] = $status->id;
        }

        foreach ($statuses as $status) {
            $statusIds[] = $status->id;
        }


        if (in_array($assignedIds, $statusIds)) {
            unset($statusIds); 
        } else {
           //pass all available statuses...
        }
    }

但是这并没有达到未设置的部分，我去了是因为两个数组的比较失败了。有谁知道如何比较两个数组之间的 id？在 $project 数组中，我想根据 $statuses id 检查嵌套数组 ["assigned_statuses"]。我怎样才能成功地实现这一点并取消设置已经分配的那些？？

Answer 1

如果$assigned_statuses 和$statuses 都是有效的数组，您可以像这样使用array_intersect 函数来比较它们：

$variable = array_intersect($assigned_statuses, $statuses); 这将搜索值的相似性，并将在两个数组之间所有匹配值的$variable 变量中构造另一个数组。

然后您可以使用 array_diff 方法在两组数组中查找唯一值
