access object array in php from json decode

April 12, 2022

I have this response from json_decode()

// Decode JSON into PHP array
$response_data = json_decode($curl_data, true);

$user_data = $response_data;
var_dump($user_data);

Response :

array(3) { ["Items"]=> array(1) { [0]=> array(3) { ["date"]=> string(9) "4/12/2022" ["ongoing"]=> string(1) "1" ["id"]=> string(1) "1" } } ["Count"]=> int(1) ["ScannedCount"]=> int(1) }

now I just wanted to get the ongoing part so I did it like this

if(!empty($user_data))
{
  foreach($user_data as $user)
  {
    var_dump($user[0]->ongoing);
  }
}

but it gives me an error

$user_data has the response above. Why is it giving me an error like that

now I have a different error when I tried this

// Decode JSON into PHP array
$response_data = json_decode($curl_data, true);

// Print all data if needed
// print_r($response_data);
// die();

// All user data exists in 'data' object
$user_data = $response_data;

if(!empty($user_data))
{
  foreach($user_data as $user)
  {
    var_dump($user[0]['ongoing']);
  }
}

>Solution :

In your loop your handle your item as object. var_dump($user[0]->ongoing); but you pass to the decode function the second parameter true. Then you return an array. Afterwards you have access like that: $user[0]['ongoing']

Update

The problem is that you have item, count and ScannedCount as key. But only item has the property ongoing. You need a condition to check if the key ongoingexists. Then it works.

$str = '{"Items":[{"date":"4/12/2022","ongoing":"1","id":"1"}],"Count":1,"ScannedCount":1}';
$user_data = json_decode($str, true);

if (! empty($user_data)) {
    foreach($user_data as $key => $value) {
        if ($key === 'Items') {
           print_r($value[0]['ongoing']);   
        }
        
    }   
}
