I am using XPATH and PHP to retrieve operational status content of an external website div

   `<?php 

  $doc = new DOMDocument;

  $doc->preserveWhiteSpace = false;

  $doc->strictErrorChecking = false;

  $doc->recover = true;

  $doc->loadHTMLFile('https://status.xero.com/');

  $xpath = new DOMXPath($doc);

  $query = "//span[@class='status']";

  $entries = $xpath->query($query);

  $info = ($entries->item(0)->textContent);



  echo '<div id="sta">' . $info .'</div>'; 

  ?>`

How can I test if the text within the target div 'status' is "All Systems Operational" example (I know it's not correct!)

 if ($entries->item(0)->textContent === "All Systems Operational"){



   echo 'YES';

 } else {

   echo 'NO';

 }

My Answer:
$url = 'https://www.externalwebsite.com';
$html = file_get_contents($url);

$doc = new DOMDocument();
$doc->loadHTML($html);

$xpath = new DOMXPath($doc);

$status = $xpath->query("//div[@class='content']")->item(0)->nodeValue;

if($status == 'Operational'){
echo 'The website is operational';
} else {
echo 'The website is not operational';
}
