Get data from Curl response coming in html formate PHP - php

Question

I am updating some records using Curl, after sending a request on the response I am getting HTML formate data. I want to check the response that, what is the response.
My code is :
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cacheManager = $objectManager->get('\Magento\Framework\App\CacheInterface');
$cacheManager->clean('catalog_product_' . $param);
$varnishurl = "www.exapmle.com";
$varnishcommand = "PURGE";
$productID = $param; // This is the Magento ProductID of the item you want to purge
$curl = curl_init($varnishurl);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $varnishcommand);
curl_setopt($curl, CURLOPT_HTTPHEADER, ['X-Magento-Tags-Pattern: catalog_product_'.$productID]);
$result = curl_exec($curl);
curl_close($curl);
OutPut:
I want to add condition to check what is returned ? either its purged like title of response or body text.I have tried by json formate sending but no luck.

Answer 1

Just change my code little bit and I got my answer. Add strip tags tag to remove HTML tags then search for what is required.
$data = strip_tags($result);
if(strpos($data, '200 Purged') !== false){
return 'Cache updated successfully for the Product Id '.$param;
}else{
return 'Some error occured during cache update for the Product Id '.$param;
}
