Grab rss feed with php and change value in rss string - php

Question

Ok I have a site where I use this code to grab the stock quote for each stock searched. <?php echo $_GET['quote'];?> What i'm trying to do is to display RSS news data by using this code below:
<?php
$rss = new DOMDocument();
$rss->load('http://feeds.finance.yahoo.com/rss/2.0/headline?s=GOOG&region=US&lang=en-USsto');
$feed = array();
foreach ($rss->getElementsByTagName('item') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
);
array_push($feed, $item);
}
$limit = 5;
for($x=0;$x<$limit;$x++) {
$title = str_replace(' & ', ' & ', $feed[$x]['title']);
$link = $feed[$x]['link'];
$description = $feed[$x]['desc'];
$date = date('l F d, Y', strtotime($feed[$x]['date']));
echo '<p><strong>'.$title.'</strong><br />';
echo '<small><em>Posted on '.$date.'</em></small></p>';
echo '<p>'.$description.'</p>';
}
?>
Do you see the "GOOG" section? that is what I'm trying to change dynamically with the quote capture code <?php echo $_GET['quote'];?> and it throws errors! Is there any other way to do this?

Answer 1

If your GET value contains a legitimate ticker code then this would work.
$rss->load('http://feeds.finance.yahoo.com/rss/2.0/headline?s='.$_GET['quote'].'&region=US&lang=en-USsto');
You are already in a php context so is not the way to concatenate a string
This is however not a robust way to handle it as there is no checking that $_GET['quote'] is set or has any value, you would need to decide what to get if it was not set
UPDATE
NB the original URL given in the question is invalid
http://feeds.finance.yahoo.com/rss/2.0/headline?s=GOOG&region=US&lang=en-USsto
does not work but
http://feeds.finance.yahoo.com/rss/2.0/headline?s=GOOG&region=US&lang=en-US
does
So please update your code to
$rss->load('http://feeds.finance.yahoo.com/rss/2.0/headline?s='.$_GET['quote'].'&region=US&lang=en-US');
