Creating a Web Spider with PHP

I used this for spidering my site.

function get_links($url) {
	$req = new httprequest();
	$html = $req->get($url);
	$regex = '/mhref/m';
	$preg = '/<a href="([^0-9].+?)"/'; // 1 or more
	$preg = '/<a href="([^0-9].*?)"/'; // 0 or more
	$urls = array ();
	preg_match_all($preg, $html, $urls);
	$count = 0;
	foreach ($urls as $url => $links) {
		if ($count == 1) {
			foreach ($links as $link) {
				echo "link-> " . $link . "\n";
			}
		}
		$count++;
	}
	echo "\n\n";
	//print_r($urls);
}
