I Would Like To Know How To Get The <link><meta> data from pages. Using PHP, I am Making A Small Blog search engine and would like to index the rss from the page. Hope There Are A Few PHP Gurus Out There.

err look up Regular Expressions
heres a good guide
http://sitescooper.org/tao_regexps.html

then use preg_match (link)
with something like /<link (?:[^\>]*)href="(.+)">/
to match the link and have it returned.

code:

---

$filename = $url;
            $handle = fopen($filename, "r");
            $contents = fread($handle, filesize($filename));
            fclose($handle);
            if (preg_match('<link (?:[^\>]*)href="(.+)">', $content)) {
                $i=0;
                $rss = array();
                while (preg_match('<link (?:[^\>]*)href="(.+)">', $content)) {
                    $url = explode('<link (?:[^\>]*)href=', $content);
                    $rss[$i] = $url[0];
                    $i++;
                }
                $amount = count($rss);
                $i=0;
                while ($amount > $i) {
                    $rssquery = "INSERT INTO rss_link (id, site_id, url) VALUES ('', '$site_id', '$rss[$i]')";
                    mysql_query($rssquery);
                }
            }

never ever use fopen for files outside your webserver. (i know atleast my host and my webserver have the url wrapper turned OFF so you cant even do that anyway)
use the curl library like. (which is way better)

code:

---

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$foo = curl_exec($ch);
curl_close($ch);

opps lol missed the $i++; lol
whats is this curl?

The CURL library isn't part of the standard PHP install as far as I know...

Why don't use file_get_contents? I don't know servers that have disabled the fopen wrappers....

Otherwise you can use:

code:

---

function get_page($host, $path, $get) {
   
   $out = "GET /$path HTTP/1.1\r\nHost: $host\r\nConnection: Close\r\n\r\n";
   
   $fp = fsockopen($host, 80, $errno, $errstr, 30);
   $in = "";
   
   fwrite($fp, $out);
   $body = false;
   while (!feof($fp)) {
       $s = fgets($fp, 1024);
       if ( $body )
           $in .= $s;
       if ( $s == "\r\n" )
           $body = true;
   }
   
   fclose($fp);
   
   return $in;
}
