JSON数据第1行第991列后面的非空白字符

我在本地有一个wordpress网站，我正在尝试使用AngularJS构建它的混合应用程序。

在wordpress中，我创建了一个插件来获取数据。我得到array形式的元数据

Array
(
[REAL_HOMES_gallery_slider_type] => Array
    (
        [0] => thumb-on-right
    )
[REAL_HOMES_property_images] => Array
    (
        [0] => 94
    )
[REAL_HOMES_property_price] => Array
    (
        [0] => 3850
    )
[REAL_HOMES_property_size] => Array
    (
        [0] => 2800
    )
[REAL_HOMES_property_bedrooms] => Array
    (
        [0] => 2
    )
[REAL_HOMES_property_bathrooms] => Array
    (
        [0] => 1
    )
[REAL_HOMES_property_garage] => Array
    (
        [0] => 1
    )
[REAL_HOMES_property_address] => Array
    (
        [0] => Athwa Gate, Surat, Gujarat 395008, India
    )
[REAL_HOMES_property_location] => Array
    (
        [0] => 21.1852392,72.80947859999992
    )
[REAL_HOMES_tour_video_url] => Array
    (
        [0] => http://vimeo.com/70301553
    )
[REAL_HOMES_featured] => Array
    (
        [0] => 1
    )
[REAL_HOMES_add_in_slider] => Array
    (
        [0] => no
    )
[REAL_HOMES_agents] => Array
    (
        [0] => 110
    )
[_dp_original] => Array
    (
        [0] => 75
    )
[REAL_HOMES_property_price_postfix] => Array
    (
        [0] => Per Month
    )
[_wp_old_slug] => Array
    (
        [0] => 15421-southwest-39th-terrace-fl
    )
[REAL_HOMES_tour_video_image] => Array
    (
        [0] => 94
    )
[REAL_HOMES_property_id] => Array
    (
        [0] => Aagam003
    )
[REAL_HOMES_property_size_postfix] => Array
    (
        [0] => Sq Ft
    )
[slide_template] => Array
    (
        [0] => default
    )
[REAL_HOMES_agent_display_option] => Array
    (
        [0] => agent_info
    )
[_edit_lock] => Array
    (
        [0] => 1436890564:1
    )
[_edit_last] => Array
    (
        [0] => 1
    )
[_thumbnail_id] => Array
    (
        [0] => 894
    )
[REAL_HOMES_slider_image] => Array
    (
        [0] => 841
    )
)

所以我把它转换成一个简单的array，得到了下面的array。

Array
(
[REAL_HOMES_gallery_slider_type] => thumb-on-right
[REAL_HOMES_property_images] => 94
[REAL_HOMES_property_price] => 3850
[REAL_HOMES_property_size] => 2800
[REAL_HOMES_property_bedrooms] => 2
[REAL_HOMES_property_bathrooms] => 1
[REAL_HOMES_property_garage] => 1
[REAL_HOMES_property_address] => Athwa Gate, Surat, Gujarat 395008, India
[REAL_HOMES_property_location] => 21.1852392,72.80947859999992
[REAL_HOMES_tour_video_url] => http://vimeo.com/70301553
[REAL_HOMES_featured] => 1
[REAL_HOMES_add_in_slider] => no
[REAL_HOMES_agents] => 110
[_dp_original] => 75
[REAL_HOMES_property_price_postfix] => Per Month
[_wp_old_slug] => 15421-southwest-39th-terrace-fl
[REAL_HOMES_tour_video_image] => 94
[REAL_HOMES_property_id] => Aagam003
[REAL_HOMES_property_size_postfix] => Sq Ft
[slide_template] => default
[REAL_HOMES_agent_display_option] => agent_info
[_edit_lock] => 1436890564:1
[_edit_last] => 1
[_thumbnail_id] => 894
[REAL_HOMES_slider_image] => 841
)

然后我用Php将这个array编码为Json。

json_encode($result);

$result是结果数组

我使用AngularJS调用了一个Ajax请求，响应给了我下面的结果。

{"REAL_HOMES_gallery_slider_type":"thumb-on-right","REAL_HOMES_property_images":"94","REAL_HOMES_property_price":"3850","REAL_HOMES_property_size":"2800","REAL_HOMES_property_bedrooms":"2","REAL_HOMES_property_bathrooms":"1","REAL_HOMES_property_garage":"1","REAL_HOMES_property_address":"Athwa Gate, Surat, Gujarat 395008, India","REAL_HOMES_property_location":"21.1852392,72.80947859999992","REAL_HOMES_tour_video_url":"http:'/'/vimeo.com'/70301553","REAL_HOMES_featured":"1","REAL_HOMES_add_in_slider":"no","REAL_HOMES_agents":"110","_dp_original":"75","REAL_HOMES_property_price_postfix":"Per Month","_wp_old_slug":"15421-southwest-39th-terrace-fl","REAL_HOMES_tour_video_image":"94","REAL_HOMES_property_id":"Aagam003","REAL_HOMES_property_size_postfix":"Sq Ft","slide_template":"default","REAL_HOMES_agent_display_option":"agent_info","_edit_lock":"1436890564:1","_edit_last":"1","_thumbnail_id":"894","REAL_HOMES_slider_image":"841"}0

我不知道为什么结尾有一个零，即使我没有在响应中附加任何东西。我猜结果是一个Json字符串，所以我尝试将其转换为Json对象来使用它并从键中获取数据。我有其他Json响应是在[]括号。但这个不是，可能是由于Json字符串响应末尾的0。

请帮帮我。谢谢。
