【问题描述】：
我正在创建代码必须遵循的角色和职责：
public function boot()
{
view()->composer('admin.sidebar', function ($view) {
$moduleRs = DB::table('users')
->join('permissions','users.role', '=', 'permissions.role_id')
->select('users.role as usersrole','permissions.role_id as role_id','permissions.module_name as module_name')
->where('users.role', '=', \Auth::user()->role)
->get();
// dd($moduleRs[0]->module_name);
$moduleData = null;
if ( count($moduleRs) > 0 ) {
$result = [];
foreach($moduleRs as $row){
if(!isset($result[$row->role_id])) {
$result[$row->role_id] = array(
'role_id' => $row->role_id,
'module_name' => [$row->module_name],
);
}else{
$result[$row->role_id]['module_name'] = array_merge($result[$row->role_id]['module_name'], [$row->module_name] );
}
}
$data=$moduleRs[0]->module_name;
dd($data);
$splittedstring[]=explode(" ,",$data);
//dd($splittedstring);
foreach ($splittedstring as $key => $value) {
echo " '.$value.'<br>";
}
}
$view->with('moduleData', $moduleData);
});
}
在上面的代码中，当我可以使用 dd($data) 时，它可以显示用户的权限 id。但是当隐藏 dd($data) 时，它也无法生成结果。请提供想法。
当我可以隐藏 dd(...) 时，它会像上面的屏幕截图一样显示..
when i put dd($splittedstring) means it shows this found below
array:3 [▼
0 => "0"
1 => "4"
2 => "5"
]
这是在以下屏幕截图中找到的模块，我可以将此模块存储在模块的模块表字段名称中
[![在此处输入图片描述][2]][2]
这是下面找到的权限表单，它必须从模块表中获取模块名称并将此值存储到模块名称的权限表字段名称中，但它是整数而不是字符串，这是外键.. [![在此处输入图片描述][3]][3]
并在视图中显示如下..这里角色 1=>超级管理员 0=>管理员...我可以将权限管理员设置为 0=>仪表板,4=>员工,5=>领导。 .当我以管理员身份登录时，我只能查看仪表板、员工和领导
