php – Json Data中的错误：Laravel 5.1

我在数组中添加元素,最后尝试将该数组转换为Json.下面是代码.

$SubCategoryList = array();

array_push($SubCategoryList,array(
                'SubCategoryID' =>  1,'FirstName'   =>  'First Name','LastName'    =>  'Last Name',));
array_push($SubCategoryList,array(
                'SubCategoryID' =>  2,'FirstName'   =>  'First Name2','LastName'    =>  'Last Name2',));

以上给出了下面提到的输出

Array
(
    [0] => Array
        (
            [SubCategoryID] => 1
            [FirstName] => First Name
            [LastName] => Last Name
        )

    [1] => Array
        (
            [SubCategoryID] => 2
            [FirstName] => First Name2
            [LastName] => Last Name2
        )

)

下面是用于将数组转换为Json的代码.

<script>
     var subCategoriesList = {{ json_encode($SubCategoryList) }};
</script>

最后json给出了以下输出.这可以在View source中看到

var subCategoriesList = [{"SubCategoryID":1,"FirstName":
"First Name","LastName":"Last Name"},{"SubCategoryID":2,"FirstName":"First Name2","LastName":"Last Name2"}];

题

Why it gives ” in the json data ?
