Show external page in the main screen of Drual

I am not sure I understand. Feeds have fixed links...

Do you mean some code which produces different links dynamically? Perhaps the l()function?

http://api.drupal.org/api/function/l/5

yes curl is a powerfull library in php you can check those links :
fr.php.net/curl and curl.haxx.se
it must be compiled with your php installation (package for php5 : php5-curl)

here is an example how to use it :

$url = "youtube.com";
$ch = curl_init();
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7";
curl_setopt($ch, CURLOPT_URL, "$url");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_NOBODY, 0);
curl_setopt($ch, CURLOPT_USERAGENT, '$agent');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, 10); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch);

this code will download the youtube.com main page.

if you want to check the result within drupal copy this code in an enable module or directy in your template with phptag function... :

function _curl_test(){
$url = "youtube.com";
$ch = curl_init();
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7";
//spoof browser
curl_setopt($ch, CURLOPT_URL, "$url");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_NOBODY, 0);
curl_setopt($ch, CURLOPT_USERAGENT, '$agent');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, 10); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch);

return $result;

now in your template : page.tpl.php or an existing template page write this somewhere in the page :

$test = _curl_test(); echo"$test";

you will see the youtube mainpage in drupal it's just the result of the curl function.

now the regular expression :

you will need to parse the curl result in order to retrieve what you need and not just the whole page, regex will do that.

download this software http://www.radsoftware.com.au/ you will be able to test your regex with this one.

search some websites with tutorials ex: www.regular-expressions.info

need some php function:
preg_match_all
preg_match

how array in php works :
array

now quick and simple example to retrieve youtube page title :

$url = "http://www.youtube.com";
$ch = curl_init();
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7";
curl_setopt($ch, CURLOPT_URL, "$url");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_NOBODY, 0);
curl_setopt($ch, CURLOPT_USERAGENT, '$agent');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, 10); 
$result = curl_exec($ch);
curl_close($ch);

$pattern = "#<title>(.*?)</title>#s";
preg_match_all($pattern, $result, $matches);

echo "<pre>"; print_r ($matches); echo "</pre>"; 
$youtube_title = $matches[1][0];
echo "$youtube_title"</pre>"; 

$pattern is the regular expression and $matches the result of the regex (array).

$youtube_title is the final result.

sorry for my english but i hope it will help you.
