Get icon from XML URL

Question

I am creating some EPG for the website. I do not have experience. Unfortunately, I'm finding it difficult. How can I get the icons, what is wrong in this code?`

Final code working:

    <?php
     $url = 'XML URL LINK';
     $xml=simplexml_load_file("$url");  
     $progs = $xml->xpath('//programme');
     foreach ($progs as $prog) {
       $title = $prog->xpath('./title/text()')[0];
       $link = (count($prog->xpath('./icon/@src'))>0) ? ($prog->xpath('./icon/@src'))[0] : ("No icon");
       echo "Logo: <img src='{$link}'> <br/>" ;
       echo "Title : ".$title. "<br>";
       echo "<br>";
     }
    ?>

This was a fun one. This uses a known hack to convert the xml into an array using json_decode and json_encode, this makes it easier to work with in my opinion. It also makes extensive use of the DateTime object.

$url = 'https://raw.githubusercontent.com/HelmerLuzo/TDTChannels_EPG/master/TDTChannels_EPG.xml';
$xml = simplexml_load_file($url);
$xml = json_decode(json_encode($xml), true); // Hack so we don't have to cast values in the future

// https://www.php.net/manual/en/timezones.php
$originalTimezone = 'Europe/Madrid';
$changeTimezone = 'Australia/Sydney'; // If empty, will not change timezone
//$outputFormat = 'Y-m-d H:i:s O';
$outputFormat = 'G:i';

$channels = [];
foreach ($xml['channel'] as $channel) {
    $id = $channel['@attributes']['id'];
    $channels[$id]['Display Name'] = $channel['display-name'];
    $channels[$id]['Now Showing'] = [];
}

$now = new DateTime('now', new DateTimeZone($originalTimezone));
$programmes = [];
foreach ($xml['programme'] as $programme) {
    $id = $programme['@attributes']['channel'];

    $start = $programme['@attributes']['start'];
    $start = DateTime::createFromFormat('YmdHis O', $start);
    if (!empty($changeTimezone))
        $start = $start->setTimezone(new DateTimeZone($changeTimezone));
    
    $stop = $programme['@attributes']['stop'];
    $stop = DateTime::createFromFormat('YmdHis O', $stop);
    if (!empty($changeTimezone))
        $stop = $stop->setTimezone(new DateTimeZone($changeTimezone));

    if ($start < $now && $now < $stop) {
        $nowShowing = [
            'Title' => $programme['title'],
            'Subtitle' => '',
            'Description' => '',
            'Date' => '',
            'Start' => '',
            'Stop' => '',
            'Icon' => '',
        ];
    
        if (isset($programme['sub-title']))
            $nowShowing['Subtitle'] = $programme['sub-title'];

        if (isset($programme['desc']))
            $nowShowing['Description'] = $programme['desc'];
    
        if (isset($programme['date']))
            $nowShowing['Date'] = $programme['date'];

        if (isset($programme['date']))
            $nowShowing['Icon'] = $programme['icon']['@attributes']['src'];

        $nowShowing['Start'] = $start->format($outputFormat);
        $nowShowing['Stop'] = $stop->format($outputFormat);
    
        $channels[$id]['Now Showing'] = $nowShowing;
    }
}

foreach ($channels as $id => $details) {
    echo $details['Now Showing']['Start'] . ' - ' . $details['Now Showing']['Stop'] . '<br>' . 
         'Channel:' . $details['Display Name'] . '<br>' . 
         'Title: ' . $details['Now Showing']['Title'] . '<br>' . 
         'Info: ' . $details['Now Showing']['Subtitle'] . '<br>' . 
         'Description: ' . $details['Now Showing']['Description'] . '<br>' . 
         'Logo: <img src="'.$details['Now Showing']['Icon'].'"/><br><br>'; 
}
