从数组响应中获取数据

Question

I've response as below.

array:4 [▼
   "response-1" => Data {#280 ▶}
   "response-2" => Exception {#235 ▼
                     #errors: array:1 [▶]
                       #message: "{"error":{"errors":[{"domain":"global","reason":"insufficientPermissions","message":"User does not have sufficient permissions for this data."}],"code":403,"message":"User does not have sufficient permissions for this data."}}"
   "response-3" => Data {#280 ▶}
   "response-4" => Data {#280 ▶}
]

Now, I need to fetch only Data part leaving the Exception part untouched from response in PHP. I don't really know how to get through it but I did try something like this:

if(!$results['response-'. $id] == 'Exception'){
      //do something
}

Answer 1

Since the array is made up of other arrays, the simplest approach is to just iterate over each element in the array and extract the values in the Data key of each element.

This assumes that your array looks something like this:

$arr = [
    "response-1" => ["Data" => ["some other array or object here"]],
    "response-2" => ["Exception" => ["some other array or object here"]],
    "response-3" => ["Data" => ["some other array or object here"]],
    "response-4" => ["Data" => ["some other array or object here"]],
];

Then getting all the Data parts would look something like this...

foreach($arr as $part) {
    if (isset($part["Data"])) {
        // Do something with $part["Data"] here
        var_dump($part["Data"]); // e.g.
    }
}

output

array(1) {
  [0]=>
  string(31) "some other array or object here"
}
array(1) {
  [0]=>
  string(31) "some other array or object here"
}
array(1) {
  [0]=>
  string(31) "some other array or object here"
}

Answer 2

The simplest way to get all of the Data values into an array:

$data = array_column($results, 'Data');

If those are actually objects, then:

$data = array_map(function($v) { return $v->Data; }, $results);
