Parsing Reddit RSS feed - PHP

I am trying to get the title and link of an rss feed -

https://www.reddit.com/r/gif.rss

(the reddit feed) 

xml=simplexml_load_file("https://www.reddit.com/r/gif.rss") or die("Error: Cannot create object");

foreach ($xml->entry->content as $x) {
$title = $x->title;
$string = $x->link;
echo $title;
echo "<br>";
echo $string;
}

I can't get title or link to appear.

Sorted it out:

$xml=simplexml_load_file("https://www.reddit.com/r/gif.rss") or die("Error: Cannot create object");

function extractString($string, $start, $end) {
    $string = " ".$string;
    $ini = strpos($string, $start);
    if ($ini == 0) return "";
    $ini += strlen($start);
    $len = strpos($string, $end, $ini) - $ini;
    return substr($string, $ini, $len);
}


foreach ($xml->entry as $x) {
$string = $x->content;

$url =  extractString($string, '<span><a href="', '">[link]</a></span>');
$title = extractString($string, 'alt="', '" title');

Simply adjust your path expression. The <content> node does not contain <title> or <link> children though their content is contained in content's text value. Instead, the nodes you need are siblings, so remove <content> in loop path:

$xml = simplexml_load_file("https://www.reddit.com/r/gif.rss") 
                              or die("Error: Cannot create object");
foreach ($xml->entry as $x) {
    $title = $x->title;
    $string = $x->link['href'];
    echo $title;
    echo "<br>";
    echo $string;
}
