Remove the parentheses around your includes and requires, and do quote literal strings.

That's just a stylistic thing and will have no bearing on the code or how it executes.

The division by 0 is coming because you're not quoting your strings as johanafm stated. Inside the require() call you need to quote the path and filename like you did with the header() call one line above it.

True, but I'd still advice against using those since they make it look like a function call but is parsed entirely differently

foo($str) {
	return 2;
}

// Works fine
$foo = foo('file.php') . 1;

// Warning: require(file.php1) failed to open stream: No such file or directory
$req = require('file.php') . 1;

// Same as above of course, but the error is more apparent (to me anyway)
$req2 = require 'file.php' . 1;

// While both these work of course
$req2 = (require 'file.php') . 1;
$req2 = (require('file.php')) . 1;

And to get back to the original question. If your errors are gone, it ought to work. Your latest question is very general and it breaks down to: retrieve the feed, possibly do something with it and finally display the results.

But perhaps you have a more specific question?

bpat1434

I'll concede that point.

hi bpat1434
That is not my intention to get entire code from you. I am trying for rss feed links in the application for the past 7 days so i asked if you people can direct me in a right way to get a help using the url sent by you.

thanks in advance friends

There are plenty of tutorials on reading RSS feeds through PHP. The simplest would be to use Simplexml and just read the feed:

<?php

$xmlstr = file_get_contents('http://www.weather.com/rss/national/rss_nwf_rss.xml');
$xml = simplexml_load_string($xmlstr);

Now the XML is stored in an iterable object which you can loop over to get all the children.

For example, to get the title of the feed above, I'd do:

echo (string) $xml->channel->title;

To get the <item> children (all the articles) I'd do:

$items = array();
foreach($xml->channel->children() as $child)
{
    if($child->getName() == 'item')
    {
        $items[] = $child;
    }
}

Alternatively you could use an xpath query to get just those results:

$results = $xml->xpath('channel/item');
while(list( , $node) = each($result))
{
    echo (string) $node->title;
}

Hope that helps you out some.

hi bpat1434

Thank you very much

i got the solution

i am posting the code for users to refer it if there are anything to be changed please let me know.

<?php

$xmlstr = file_get_contents('http://www.indiaedunews.net/rss/today.xml');
$xml = simplexml_load_string($xmlstr);

echo (string) $xml->channel->title; 

$items = array();
foreach($xml->channel->children() as $child)
{
    if($child->getName() == 'item')
    {
        $items[] = $child;
    }
}

$results = $xml->xpath('channel/item');
/*print "<br>";
print ("<pre>");
print_r($results); 
print ("</pre>");*/

//print count($results)."<br>";

while(list( , $node) = each($results))
{
    $newsstring= (string) $node->title;

	echo "<a href=".(string)$node->link.">".$newsstring."</a>";
	echo "<br>";

//	print($newsstring)."<br>";
	/*for($i=0; $i<count($results); $i++)
	{*/
	/*}*/

} 
?>
