php laravel array_merge键值

[英]php laravel array_merge key value

嗨,我正在创建一个数组,它将在我的网站中存储部分。 这些部分中的某些部分将对某些用户不可用,因此在放入阵列之前,我需要检查相关用户的许可。 但是,当我执行此if语句时,我在不需要的数组中得到一个数组,这会导致以下错误:

Method Illuminate\\View\\View::__toString() must not throw an exception

这是我正在使用的代码:

$user = Auth::user(); 
 if(($user->hasRole('Admin') || $user->hasRole('Admin') || $user->hasRole('Project Master') || $user->hasRole('Project Owner'))) {
  $restrictsections = ['Create' => route('project.create'),
                       'Sort' => route('project.sort'),];
  }

$this->sections = [
    'Projects' => [
        'View' => route('project.index'),
        $restrictsections

    ]
];

现在,数组的结构如下:

array(1) {
  ["Projects"]=>
  array(2) {
    ["Create"]=>
    string(30) "http://projects.local/projects"
    [0]=>
    array(2) {
      ["Create"]=>
      string(37) "http://projects.local/projects/create"
      ["Edit"]=>
      string(35) "http://projects.local/projects/sort"
    }
  }
}

相对于:

  $this->sections = [
        'Project' => [
            'View' => route('project.index'),
            'Create' => route('project.create'),
             'Sort' => route('project.sort'),
        ]
    ];


array(1) {
  ["Project"]=>
  array(3) {
    ["View"]=>
    string(30) "http://projects.local/project"
    ["Create"]=>
    string(37) "http://projects.local/project/create"
    ["Sort"]=>
    string(35) "http://projects.local/project/sort"
  }
}

有什么想法可以将两个数组合并在一起吗? 但其结构应如下:

array(1) {
  ["Project"]=>
  array(3) {
    ["View"]=>
    string(30) "http://projects.local/project"
    ["Create"]=>
    string(37) "http://projects.local/project/create"
    ["Sort"]=>
    string(35) "http://projects.local/project/sort"
  }
}

再创建一个

$this->sections = ['Projects' =>  $restrictsections];
$this->sections['Projects']['View'] = route('project.index');

您可以使用+运算符组合数组。

例如:

php > print_r(['View' => '1'] + ['Create' => 'two', 'Sort' => '3']);
Array
(
    [View] => 1
    [Create] => two
    [Sort] => 3
)

适用于您的代码:

$user = Auth::user(); 
 if(($user->hasRole('Admin') || $user->hasRole('Admin') || $user->hasRole('Project Master') || $user->hasRole('Project Owner'))) {
  $restrictsections = ['Create' => route('project.create'),
                       'Sort' => route('project.sort'),];
  }

$this->sections = [
    'Projects' => [
        'View' => route('project.index')
    ] + $restrictsections
];

编辑: +从技术上讲是一个并集,因此,如果第二个数组中的键出现在第一个数组中,则将忽略它们。

像这样使用array_merge()

$this->sections = [
    'Projects' => array_merge(
        ['View' => route('project.index')],
        $restrictsections
    )
];

或像这样使用+运算符

$this->sections = [
    'Projects' => ['View' => route('project.index')] + $restrictsections
];
