用php删除json中的记录

Question

我想通过在提交前将status更改为DELETE来删除JSON中的记录。

JSON：

{
Shawn Taylor: {
  name: "Shawn Taylor",
  title: "Director",
  photo_url: "Creative-ShawnTaylor.jpg",
  status: "Current"
},

Shawn Taylor 2: {
  name: "Shawn Taylor 2",
  title: "Photographer",
  photo_url: "Creative-ShawnTaylor2.jpg",
  status: "DELETE"
}

我从JSON读到就好了：

$data_url = 'data.json';
$data_json = file_get_contents($data_url);
$data_array = json_decode($data_json, true);
//plus a bunch of _GET stuff here...
...

// then write to JSON like so
$data[$name] = array(
    'name' => $name,
    'title' => $title,
    'photo_url' => $photo_url,
    'status' => $status
    );

//EDIT - this is my feeble attempt
if($status == 'DELETE'){
    unset($data[$name]);
};
//END EDIT

// merge and write array to json    
$data_array = array_merge($data_array, $data);
file_put_contents('data.json', json_encode($data_array, JSON_FORCE_OBJECT));

但无法弄清楚如何删除记录...

我可以看到，你试图在php中删除部分json。

您可以使用此代码：

foreach($data as $key=>$val){
   // check status
   if ($val["status"]=="DELETE"){
      // this deletes record from array
      unset($data[$key]);
   }
}

file_put_contents('data.json', json_encode($data, JSON_FORCE_OBJECT));
