Get next title from XML link in PHP-CodePudding

I'm parsing XML link. I'm getting the title of the broadcast now, but i can't to get the title of the next broadcast. If anyone can help me, I would be grateful,

  <?php
     $url = 'https://hls.airy.tv/airytv/33';
     $xml=simplexml_load_file("$url"); 
     $line = 0;
     $time = date( "YmdHi" );
     foreach($xml->xpath('programme[@channel="33"]') as $item) {
       $start = substr( (string)$item["start"], 0, -8);
       $end   = substr( (string)$item["stop"], 0, -8);
           if ($time > $start && $time < $end) {
               echo "Now : ".$item->title. "<br>";
               echo "Next : ".$item->title.[$line 1];
           }
       $line  ;
     }
  ?>

CodePudding user response：

Try this, it is working for me:

<?php
$url = 'https://hls.airy.tv/airytv/33';
$xml=simplexml_load_file("$url");
$time = date( "YmdHi" );

$currTitle = null;
$nextTitle = 'N/A';

foreach($xml->xpath('programme[@channel="33"]') as $item)
{
    if ($currTitle != null)
    {
        $nextTitle = $item->title;
        break;
    }

    $start = substr( (string)$item["start"], 0, -8);
    $end   = substr( (string)$item["stop"], 0, -8);
    if ($time > $start && $time < $end)
    {
        $currTitle = $item->title;
    }
}

echo "Now : $currTitle<br />Next : $nextTitle";
?>

I don't think you can do a lookahead like you're trying to do with the foreach, so you can just save off the the title when you find the record with the appropriate time, and let the loop progress one more time to pick up the next record.
