Change die to not stop code from executing - php

Question

In the code below, the code would stop from executing further when Kiyoh would not be reachable. This is not good for production. So I was wondering what the best way would be to replace the die function, in a way that the content would execute further -even when Kiyoh would not be reachable-.
The code looks like:
<?php
// Get KiyOh rating
$readdir = $_SERVER['DOCUMENT_ROOT'] . '/kiyoh/';
$file = 'kiyohdata.dat';
// Open the file to get existing content
$kiyohdata = file_get_contents($readdir . $file);
if( $kiyohdata === false ) { // NOT CACHED
$xml = simplexml_load_file('https://www.kiyoh.nl/widgetfeed.php?company=YYYYY') or die("Error: Cannot create object");
$kiyohdata = explode(",", $xml->channel->description);
if(!empty($kiyohdata)) {
file_put_contents($readdir . $file, serialize($kiyohdata));
}
} else { // IS CACHED
$kiyohdata = unserialize($kiyohdata);
}
$cijfer = str_replace('Average score ', '', $kiyohdata[0]);
$cijfer = str_replace('.', ',', $cijfer);
$aantal = str_replace(' Total reviews ', '', $kiyohdata[2]);
?>
I tried with placing an exception: throw new Exception("Kiyoh is not available at the moment");, but the page crashes anyway (Magento 1.9.4.3 webshop).
