How to display a readable array - Laravel
提问by Gilko
After I write:
我写完之后：
Route::get('/', function()
{
dd(User::all());
});
And after I refresh the browser I get an unreadable array. Is there a way to get that array in a readable format?
刷新浏览器后，我得到一个不可读的数组。有没有办法以可读的格式获取该数组？

dd()dumps the variable and ends the execution of the script (1), so surrounding it with <pre>tags will leave it broken. Just use good ol' var_dump()(or print_r()if you know it's an array)
dd()转储变量并结束脚本(1)的执行，因此用<pre>标签包围它会使其损坏。只需使用好的 ol' var_dump()（或者print_r()如果您知道它是一个数组）
Route::get('/', function()
{
echo '<pre>';
var_dump(User::all());
echo '</pre>';
//exit; <--if you want
});
Update:
更新：
I think you could format down what's shown by having Laravel convert the model object to array:
我认为您可以通过让 Laravel 将模型对象转换为数组来格式化显示的内容：
Route::get('/', function()
{
echo '<pre>';
$user = User::where('person_id', '=', 1);
var_dump($user->toArray()); // <---- or toJson()
echo '</pre>';
//exit; <--if you want
});
(1) For the record, this is the implementation of dd():
(1) 为了记录，这是 dd() 的实现：
function dd()
{
array_map(function($x) { var_dump($x); }, func_get_args()); die;
}

actually a much easier way to get a readable array of what you (probably) want to see, is instead of using
实际上，一种更简单的方法来获取您（可能）想要看到的可读数组，而不是使用
dd($users);
or
或者
dd(User::all());
use this
用这个
dd($users->toArray());
or
或者
dd(User::all()->toArray());
which is a lot nicer to debug with.
这是更好的调试。
EDIT - additional, this also works nicely in your views / templates so if you pass the get all users to your template, you can then dump it into your blade template
编辑 - 另外，这也适用于您的视图/模板，因此如果您将获取所有用户传递给您的模板，您可以将其转储到您的刀片模板中
{{ dd($users->toArray()) }}

Maybe try kint: composer require raveren/kint "dev-master" More information: Why is my debug data unformatted?
也许试试kint：composer require raveren/kint "dev-master" 更多信息：为什么我的调试数据没有格式化？

For everyone still searching for a nice way to achieve this, the recommended way is the dump()function from symfony/var-dumper.
对于仍在寻找实现此目的的好方法的每个人，推荐的方法是dump()从symfony/var-dumper.
It is added to documentation since version 5.2: https://laravel.com/docs/5.2/helpers#method-dd
它从 5.2 版开始添加到文档中：https: //laravel.com/docs/5.2/helpers#method-dd

I have added a helper da()to Laravel which in fact works as an alias for dd($object->toArray())
我da()在 Laravel 中添加了一个助手，它实际上是dd($object->toArray())

回答by novecentonove
as suggested, you can use 'die and dump' such as dd($var)
or only 'dump', without dying, dump($var)
按照建议，您可以使用“die and dump”，例如 dd($var)
或仅使用“dump”，而不会死亡， dump($var)

You can use this code on view.blade. {{var_dump($animales)}}
您可以在 view.blade 上使用此代码。{{var_dump($animales)}}

You can use var_dumpor print_rfunctions on Blade themplate via Controller functions :
您可以通过控制器功能在 Blade 模板上使用var_dump或print_r功能：
class myController{
public function showView(){
return view('myView',["myController"=>$this]);
}
public function myprint($obj){
echo "<pre>";
print_r($obj);
echo "</pre>";
}
}
And use your blade themplate :
并使用您的刀片模板：
$myController->myprint($users);
