cURL problem

[Norky]

I'm writing an RSS reader in PHP, that will read remote feeds.

To do this I am using fread() to get the data, but I also need to get the size of the feed, so I'm using a cURL function:

ob_start();
 $ch = curl_init($uri);
 curl_setopt($ch, CURLOPT_HEADER, 1);
 curl_setopt($ch, CURLOPT_NOBODY, 1);
 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
 if (!empty($user) &&!empty($pw))
 {
 $headers = array('Authorization: Basic ' . base64_encode($user.':'.$pw)); 
 curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
 }
 $okay = curl_exec($ch);
 curl_close($ch);
 $head = ob_get_contents();
 ob_end_clean();
 $regex = '/Content-Length:\s([0-9].+?)\s/';
 $count = preg_match($regex, $head, $matches);
 if (isset($matches[1]))
 {
 $size = $matches[1];
 }
 else
 {
 $size = 0;
 }
 
 return $size;

This all works dandy, except for feeds generated by PHP/ASP where the content type is sent using a header(); and the XML is generated from a database or whathaveyou.

What can I do to make it see the final outputted data? I thought CURLOPT_HEADER would do this. Or is there an altogether simpler way of obtaining remote data?

Welcome to WebmasterWorld, Norky.

When you say size of the feed, do you mean the length of the contents? If so, why not just use file_get_contents() [php.net] and strlen() [php.net]?
