earningsChart->quarterly->actual->raw
Let me know if anyone can help me for same. I am trying from last hour but not able to get idea what I should do .
Thanks!

Your result node is an array of objects, so it be probably:
echo $data['quoteSummary']['result'][0]['summaryDetail']['priceHint']['raw'];
