How to use curl option

[ym_chaitu]

Hai
i am using the curl option to validate the site for the rss feed.
my code is

<?php
// create a new cURL resource
$ch = curl_init();
$demo='http://chaitu09986025424.blog.co.in/feed/rss/';
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://validator.w3.org/feed/check.cgi?url=$demo");
curl_setopt($ch, CURLOPT_HEADER, false);

// grab URL and pass it to the browser
curl_exec($ch);
echo $info['http_code'] . " " . $http_codes[$info['http_code']];
// close cURL resource, and free up system resources
curl_close($ch);
?>

now the problem is that how do i read the file and pass the parameters...
the result of this would be

Congratulations!
This is a valid RSS feed.

Recommendations
This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.

Try this:

<?php
// create a new cURL resource
$ch = curl_init();
$demo='http://chaitu09986025424.blog.co.in/feed/rss/';
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://validator.w3.org/feed/check.cgi?url=$demo");
curl_setopt($ch, CURLOPT_HEADER, false);

// grab URL and pass it to the browser
$data=curl_exec($ch);
echo $info['http_code'] . " " . $http_codes[$info['http_code']];
// close cURL resource, and free up system resources
curl_close($ch);

//$data
//contains the result
?>

i have tried this one but still i am not getting any information..
The same info which i am getting using the curl_exec($ch);
there is no result getting displayed using the

echo $info['http_code'] . " " . $http_codes[$info['http_code']];

Didn't realize you were trying to get those two variables to work but the data from the result is stored in the $data variable and should be possible to use the preg_match_all function to find the appropriate section of data.
