Michael, I wrote this function for a project that I'm working on. It
returns an indexed array of local links found on a given page. It returns
false if the url is not a valid file. If you want it to return all links
regardless of prefix or file extension then just return $arrayoflinks[1]
instead of doing the extra ereg() steps. It's a very simple function, but
it may help get you started.
-Kevin
function extract_links($url)
{
$fp = fopen($url, "r"); // fopen to check for valid file
if ($fp !== false)
{
fclose($fp);
$contents = implode("", file($url));
// Much thanks to whomever wrote this regex!
preg_match_all("|href=\"?([^\"' >]+)|i", $contents, $arrayoflinks);
foreach ($arrayoflinks[1] as $link)
{
// Ignore links that may not be local.
if (!ereg('http://', $link))
{
// Make sure the link is some form of html file.
if (ereg('.htm', $link))
{
// Build array of local links on this page.
$links[] = $link;
}
}
}
return $links;
}
else
{
return false;
}
}
