This is a simple function to extract link from a specific page/URL : function extract_url($main_url){

$f = fopen($main_url,"r");
$inputStream = fread($f,65535);
fclose($f);
if (preg_match_all("/(.*?)<\/a>/i”,$inputStream,$matches)) {
foreach($matches[1] as $link){
if(!eregi(’mailto:|javascript:|ymsgr:’,$link)){
if(eregi(”http://”,$link)){
$url = $link;
}
else{
$url = $prefix_url.$link;
}
if(eregi(’PHPSESSID’,$url)){
$url = explode(”PHPSESSID”,$url);
$url = substr($url[0],0,-1);
}
$output[] = $url;
}
}
}
return array_unique($output);
}
?>


And here is sample how to use the function: $start = time();
print_r(extract_url("http://dev.sandalian.com/"));
$end = time();

echo 'done in '.($end-$start).' second';
?>


This script only working when remote_url are allowed. Otherwise you will need to use CURL.
