Parsing JSON object foreach-CodePudding

I can't access my object in json for all. I can access for one by one but i want to print foreach object. I'm trying to get 'txID' for each array.But it's printing nothing. I've already tired the given solution on Parsing JSON array with PHP foreach But it didn't work.

Here is my json

PHP Code

$url = 'https://api.trongrid.io/v1/accounts/TQ82FS4og14am8BXqndHX8HrYYARrhmjBk/transactions?only_confirmed=true&only_to=true&limit=3';

$content = file_get_contents($url);
$array = json_decode($content, true);

foreach ($array as $value) {
    
   echo $value{txID};
}

Although,i can get the id when i declare a specific object number. Example

foreach ($array as $value) {
        
       echo $value[0]{txID};
    }

CodePudding user response：

Your JSON is not an array, it's an object. The data property in this object is the array you want.

$obj = json_decode($content, true);

foreach ($obj['data'] as $value) {
   echo $value['txID'];
}
