print encoded or decoded json in readable format - php

Question

I am using php curl to get account and transaction data from the plaid api. I'd like to see it in a nice format so I can go about creating loops to save the information into a database. The decoded json output, when printed with print_r, is returned like this:
array ( [accounts] => Array ( [0] => Array ( [_id] => QPO8Jo8vdDHMepg41PBwckXm4KdK1yUdmXOwK [_item] => KdDjmojBERUKx3JkDd9RuxA5EvejA4SENO4AA [_user] => eJXpMzpR65FP4RYno6rzuA7OZjd9n3Hna0RYa [balance] => Array ( [available] => 1203.42 [current] => 1274.93 ) [institution_type] => fake_institution [meta] => Array ( [name] => Plaid Savings [number] => 9606 ) [subtype] => savings [type] => depository ) [1] => Array ( [_id] => nban4wnPKEtnmEpaKzbYFYQvA7D7pnCaeDBMy [_item] => KdDjmojBERUKx3JkDd9RuxA5EvejA4SENO4AA...
I'd like to get it looking like this:
Array (
[accounts] => Array (
[0] => Array (
[_id] => QPO8Jo8vdDHMepg41PBwckXm4KdK1yUdmXOwK
[_item] => KdDjmojBERUKx3JkDd9RuxA5EvejA4SENO4AA
[_user] => eJXpMzpR65FP4RYno6rzuA7OZjd9n3Hna0RYa
[balance] => Array (
[available] => 1203.42
[current] => 1274.93 )
[institution_type] => fake_institution
[meta] => Array (
[name] => Plaid Savings
[number] => 9606 )
[subtype] => savings
[type] => depository )
[1] => Array (
[_id] => nban4wnPKEtnmEpaKzbYFYQvA7D7pnCaeDBMy
[_item] => KdDjmojBERUKx3JkDd9RuxA5EvejA4SENO4AA
`
For reference, here is the code to get the response:
$data = array(
"client_id"=>"test_id",
"secret"=>"test_secret",
"access_token"=>"test_chase"
);
$string = http_build_query($data);
//initialize session
$ch=curl_init("https://tartan.plaid.com/connect/get");
//set options
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//execute session
$accountData = json_decode(curl_exec($ch), true);
print_r($accountData);
//close session
curl_close($ch);
Any thoughts other than loops?
