I am trying to using this API.   https://www.blocktrail.com/api/docs

 

 

I can retrieve the first layer value using this.

$global_trans_id        = $client->transaction($post_transid);
$api_transaction_id	= $global_trans_id['hash'];
echo $api_transaction_id;

As you see "hash" is the first layer below. But what if I want to retrieve the second layer such as a value from "Inputs" or "Outputs" like "$global_trans_id['address'];". How would that look?

Sepodati is correct. But to your specific question:

 

 

echo $global_trans_id['inputs'][0]['address'];
As already pointed out, the sample data you provided shows that both the 'inputs' and 'outputs' keys are array (note: [ ] ).

 

Each array has apparently a variable number of elements in the array. So if you wanted to see all the addresses:

 

foreach ($global_trans_id['inputs'] as $value) {
    
    echo "Address:  {$value['address']} <br>";
}
