Creating Array of data in laravel controller
提问by Ronald Torres
$document = new Document();
$document->title = $request['title'];
$document->description = $request['description'];
When i try to output the above code using echo $document;i get this result:
当我尝试使用输出上述代码时，echo $document;我得到以下结果：
{"title":"asdfasdf","description":"asdfasdfsadf"}
What i want is to create my own array of data and output the same format. This is the code i am trying to experiment but it does not work:
我想要的是创建我自己的数据数组并输出相同的格式。这是我尝试尝试的代码，但它不起作用：
$data = array(
"title" => "hello",
"description" => "test test test"
);
echo $data;
Any Help would be appreciated. Thanks.
任何帮助，将不胜感激。谢谢。

All collections also serve as iterators, allowing you to loop over them as if they were simple PHP arrays:
所有集合也用作迭代器，允许您循环遍历它们，就像它们是简单的 PHP 数组一样：
foreach ($document as $data) {
echo $data->title;
echo $data->description;
}
There is no difference while using a PHP framework. You may refer the official PHP Arrays Manualpage to work with the language construct.
使用 PHP 框架时没有区别。您可以参考官方PHP 数组手册页面来使用语言结构。
If you need to convert JSON to array, use:
如果您需要将 JSON 转换为数组，请使用：
$data->toArray();
$data->toArray();
OR
或者
json_decode($data);
json_decode($data);
Here is your code:
这是你的代码：
$data = array(
"title" => "hello",
"description" => "test test test"
);
// may also declare
// 也可以声明
$data = ["title" => "hello", "description" => "test test test"];
Use:
用：
var_dump($data);
var_dump($data);
OR
或者
print_r($data);
打印_r($数据);
// and the output will be
// 输出将是
["title" => "hello", "description" => "test test test",]
