将 die 更改为不停止执行代码

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).

        $kiyohdata = explode(",", $xml->channel->description);

            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]);
