Getting Other Site's Data

[Anon]

Basically I want to return another sites html (got this already) and then get stuff between certain tags and format them and output them (like, getting stuff from amazon.com based on a query.)

I remember I had a function to do this awhile ago, but lost it.

If anyone can help me with this I'd be most appreciative. Thanks.

$file = fopen("http://www.php.net/", "r");
if (!$file) {
echo "<p>Unable to open remote file.\n";
exit;
}
while (!feof($file)) {
$line = fgets($file, 1024);

/ This only works if the title and its tags
are on one line.
*/

if (eregi("<title>(.*)</title>", $line, $out)) {
$title = $out[1];
break;
}
}
fclose($file);
