使用mysql_fetch_assoc的JSON多维数组

Question

我的Mysqli更新查询，并输出此

SELECT milestone.id, milestone.name, milestone.date, milestone.location, milestone.story_body, milestone.short_link, milestone.created_at, 
GROUP_CONCAT(images.path) as path , images.update_type
FROM milestone
INNER JOIN images ON milestone.id = images.update_id
WHERE milestone.business_id =  '1' && milestone.status =  '1' && images.update_type =  '3'
GROUP BY milestone.id

如何使用上述查询形成JSON对象？

我试过下面的方法，不会产生任何结果

$result_array = array();
while($row = mysql_fetch_assoc($result))
{
    $result_array[] = $row;

}

我想要这样的东西-

[  
       {  
          "id":"4",
          "name":"2nd anniversary",
          "date":"2015-12-17",
          "location":"Mumbai",
          "story_body":"Gzjjs jdk djks jdks jdkd jx djdb djd JD djbd djdj d",
          "short_link":"izWfs",
          "created_at":"2015-12-11 03:49:52",
          "path":
                 [                       
                   {"\/SupportData\/ImpalzB2B\/uploads\/90294930451448437444826.jpg"},
                   {"\/SupportData\/ImpalzB2B\/uploads\/90294930451449758248579.jpg"}
                 ],
          "update_type":"3"
       },       
       {  
          "id":"7",
          "name":"#1styearAnniversary",
          "date":"2016-01-20",
          "location":"Mumbai",
          "story_body":"Bsjsj jdkdk djdkdk dkdkf kdkf dkfj fjfj fjfkjdd djkd",
          "short_link":"FHXh0",
          "created_at":"2016-01-20 23:10:54",
          "path":"\/SupportData\/ImpalzB2B\/uploads\/11453356652175.jpg",
          "update_type":"3"
       }
    ] 

注意：我知道Mysql在PHP 7中没有使用。我需要用PDO和Mysqli替换它，因此请忽略该错误。 我正在同一个工作，与此同时面对这个查询。

您现在可以执行此操作-

$result_array = array();
while($row = mysql_fetch_assoc($result))
{
    $temp= explode(',', $row['path']); // explode by ,
    if(count($temp) > 1) { // More than one element then assign
        $row['path']= $temp;
    } 
    $result_array[] = $row;
}
