jquery JSON没有从jQ AJAX请求解析(jquery JSON not parsing from jQ AJAX request)

 我对jQuery相当陌生，我的JSON数据似乎没有解析我期望的方式。 
 
 所以我用json_encode（$ var）创建了我的数据; 在PHP中，这似乎工作正常： 
 
{"id":"7","0":"7","ip":"86.152.117.159","1":"86.152.117.159","proxyip":"86.152.117.159","2":"86.152.117.159","ping":"1","3":"1","time":"03:39:17","4":"03:39:17"}{"id":"6","0":"6","ip":"86.152.117.159","1":"86.152.117.159","proxyip":"86.152.117.159","2":"86.152.117.159","ping":"1","3":"1","time":"03:36:20","4":"03:36:20"}
 
 （这是通过jQuery的AJAX从同一服务器/域上的单独URL导入的）。 
 
 但是，当我使用此代码尝试导入它时： 
 
$.ajax({url:"load.php",success:function(result){
            var obj = jQuery.parseJSON(result);
            $(".response").html(obj.id);
        }});
 
 并检查我的控制台，我得到“Uncaught SyntaxError：Unexpected token {”，它指向index.php中的“第1行” - 注意我没有使用外部JS文件。 
 
 我不知道我做错了什么以及如何解决这个问题所以我可以在页面上以非json形式显示数据（即在表格中） 
 
 任何帮助是极大的赞赏！ 
 
 编辑： 
 
 这是我的load.php文件： 
 
try {
    $db = new PDO("mysql:host=$mysql_host;dbname=$mysql_db", $mysql_user, $mysql_pass);
} catch(PDOException $e) {
    $e->getMessage();
}

$update = "SELECT * FROM traffic";
foreach ($db->query($update) as $user) {
    echo json_encode($user);
}

I'm fairly new to jQuery and my JSON data doesn't seem to be parsing the way i expect it to be.
 
So i've created my data by json_encode($var); in PHP and that seems to work fine:
 
{"id":"7","0":"7","ip":"86.152.117.159","1":"86.152.117.159","proxyip":"86.152.117.159","2":"86.152.117.159","ping":"1","3":"1","time":"03:39:17","4":"03:39:17"}{"id":"6","0":"6","ip":"86.152.117.159","1":"86.152.117.159","proxyip":"86.152.117.159","2":"86.152.117.159","ping":"1","3":"1","time":"03:36:20","4":"03:36:20"}
 
(This is being imported via jQuery's AJAX from a separate URL on the same-server/domain).
 
But when i use this code to try to import it:
 
$.ajax({url:"load.php",success:function(result){
            var obj = jQuery.parseJSON(result);
            $(".response").html(obj.id);
        }});
 
and check my console, i get "Uncaught SyntaxError: Unexpected token {" which points to "line 1" in index.php - Note i'm not using an external JS file.
 
I don't know what i'm doing wrong and how i should go about fixing the issue so i can display the data in a non-json form on the page (i.e in a table)
 
Any help is greatly appreciated!
 
Edit:
 
Here's my load.php file:
 
try {
    $db = new PDO("mysql:host=$mysql_host;dbname=$mysql_db", $mysql_user, $mysql_pass);
} catch(PDOException $e) {
    $e->getMessage();
}

$update = "SELECT * FROM traffic";
foreach ($db->query($update) as $user) {
    echo json_encode($user);
}
