extracting urls for site search....

[Anon]

Hi everyone

Does anyone have a script/link for extracting links from a web page?

I'm going to build a site search and I'm hopeless at regex so thought to ask if any of you had done this already ;-)

Many thanks....

If you search the manual long enough you're bound to find that somebosy has written if for you ;-)

<?
$url = "http://anydomainname/anyfile";

$contents = Implode("", File($url));

preg_match_all("|href=\"?([^\"' >]+)|i", $contents,
$arrayoflinks);

//Listing the array
While(List(,$link) = Each($arrayoflinks[1]))
Echo "$link<Br>";
