For Loop without second condition

Question

<?php
    $val = $_GET["val"];
    $url = "http://feeds.bbci.co.uk/news/rss.xml";
    $xml = simplexml_load_file($url);

    for($i = 0; $i < 10 ; $i++){    
        $title = $xml->channel->item[$i]->title;
        $link = $xml->channel->item[$i]->link;
        $description = $xml->channel->item[$i]->description;
        $pubDate = $xml->channel->item[$i]->pubDate;
        $rss .= "<a href='$link'><h3>$title</h3></a>";
        $rss .= "$description";
        $rss .= "<br />$pubDate<hr />";
   }
   echo $rss;
?>

Hello everyone! I have a problem here. I would like to list all the results for the rss link but it gets only 10. I know that I have the second condition for "for loop" as $i<10, but how can I remove that condition, and get all the results from the rss link?

If you want to loop over every item instead of 10, then get the amount/count of items you want to loop over, and put that in the spot of the 10... — Ivar, Jul 20 '17 at 12:35
The `$i < 10` isn't a second condition, it's the only one. The `$i = 0` isn't a condition, it's an assignment. — Rafael Barros, Jul 20 '17 at 12:45

Use foreach instead of for:

<?php
$url = "http://feeds.bbci.co.uk/news/rss.xml";
$xml = simplexml_load_file($url);
$rss = '';

foreach ($xml->channel->item as $item) {

    $title = $item->title;
    $link = $item->link;
    $description = $item->description;
    $pubDate = $item->pubDate;

    $rss .= "<a href='$link'><h3>$title</h3></a>";
    $rss .= "$description";
    $rss .= "<br />$pubDate<hr />";
}
echo $rss;
?>

Either you can use foreach loop or count the size of an array and then use this size to set the second condition in your for loop..
