How to print arrays inside array by Laravel blade?
提问by narsis fe
My function returns an array to a variable in laravel blade page like this :
我的函数将数组返回到 laravel 刀片页面中的变量，如下所示：
Array
(
[id] => 1
[name] => Enterpise
[children] => Array
(
[0] => Array
(
[id] => 2
[name] => name1
[children] => Array
(
[0] => Array
(
[id] => 5
[name] => name2
[children] =>
)
[1] => Array
(
[id] => 6
[name] => name3
[children] => Array
(
[0] => Array
(
[id] => 11
[name] => name4
[children] =>
)
.....
Now I want to print these values inside my page by using something like foreach. Consider that their children's numbers are not specified, it is impossible to do that inside of my function. It is important to me to be done in blade. How can I do that?
现在我想通过使用类似的东西在我的页面中打印这些值foreach。考虑到没有指定他们孩子的号码，在我的函数内部不可能做到这一点。在刀片中完成对我来说很重要。我怎样才能做到这一点？

In your blade files you can use any php functions like print_r().
在您的刀片文件中，您可以使用任何 php 函数，例如print_r().
Example:
例子：
{{ print_r($array) }}

As this is very old issue but I found jsondirective very useful.
由于这是一个非常古老的问题，但我发现json指令非常有用。
<pre>
<code>
@json($array);
</code>
</pre>

@php
echo "<pre>";
print_r($array);

Or you can use: {{ echo json_encode($yourarray) }}
或者你可以使用：{{ echo json_encode($yourarray) }}
but this will print your array as json encoded string.
但这会将您的数组打印为 json 编码的字符串。
