在laravel中，如何使用foreach循环？

Question

当我使用此代码时：

Route::get('/user/{id}/posts', function ($id){
   $post = User::find($id)->postst;
   return $post;
});

输出为：

[
    {
        "id":1,
        "user_id":1,
        "title":"Eloquent Basic Insert",
        "content":"By eloquent we can easily insert a data and it is awesome",
        "created_at":"2018-05-15 14:45:34",
        "updated_at":"2018-05-15 14:45:34",
        "deleted_at":null
    },
    {
        "id":2,
        "user_id":1,
        "title":"Add with create",
        "content":"This might be fail",
        "created_at":"2018-05-15 14:47:59",
        "updated_at":"2018-05-15 14:47:59",
        "deleted_at":null
    }
]

但是当我使用foreach循环时，它仅显示数组之一

 Route::get('/user/{id}/posts', function ($id){
   $post = User::find($id)->postst;
   foreach ($post as $post){
       return $post->title. '<br>';
   }
});

此代码的输出为：

您正在做的是在第一个循环中返回标题。您需要把自己return的foreach：

Route::get('/user/{id}/posts', function ($id){
   $post = User::find($id)->postst;
   $titles = "";
   foreach ($post as $post){
       $titles .= $post->title. '<br>';
   }
   return $titles;
});
