Can't fetch XML response in PHP - php

Question

This is my code to fetch api
$apiurl = "https://class.cvcngr.in/bigbluebutton/api/create?allowStartStopRecording=true&attendeePW=ap&autoStartRecording=false&meetingID=random-1495797&moderatorPW=mp&name=random-1495797&record=false&voiceBridge=74999&welcome=%3Cbr%3EWelcome+to+%3Cb%3E%25%25CONFNAME%25%25%3C%2Fb%3E%21&checksum=ad1f82091f78ee18673f9c5be36df9eef7860187";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $apiurl);
$response = curl_exec($ch);
curl_close($ch);
$xml = simplexml_load_string($response);
echo $xml;
In the above, I have used an apiurl which stores URL of API. this is my custom API and there is a test API provided by the service provider
$apiurl2 "http://test-install.blindsidenetworks.com/bigbluebutton/api/create?allowStartStopRecording=true&attendeePW=ap&autoStartRecording=false&meetingID=random-9370670&moderatorPW=mp&name=random-9370670&record=false&voiceBridge=79891&welcome=%3Cbr%3EWelcome+to+%3Cb%3E%25%25CONFNAME%25%25%3C%2Fb%3E%21&checksum=0aae50d2d079fd67138a7b266837f6b0112166b5";
Bothe the URL gives the same response but I can get data only when I use apiurl2. when I use the first one there is no response. but when I use in the browser directly there is no issues

It works just fine, the $xml variable is a SimpleXMLElement instance. echo tries to print a string. You can print all of its contents with var_dump($xml) and access its elements directly with an object operator: echo $xml->dialNumber and even loop thru them:
<?php
$apiurl = "https://class.cvcngr.in/bigbluebutton/api/create?allowStartStopRecording=true&attendeePW=ap&autoStartRecording=false&meetingID=random-1495797&moderatorPW=mp&name=random-1495797&record=false&voiceBridge=74999&welcome=%3Cbr%3EWelcome+to+%3Cb%3E%25%25CONFNAME%25%25%3C%2Fb%3E%21&checksum=ad1f82091f78ee18673f9c5be36df9eef7860187";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $apiurl);
$response = curl_exec($ch);
$xml = simplexml_load_string($response);
// var_dump($xml);
// echo 'Dial number: ' . $xml->dialNumber;
foreach ($xml as $key => $value) {
echo "{$key}: {$value}\n";
}
curl_close($ch);
