[PHP] getting anchor tags
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi In theory I can work out how to get a href= tags from a page. Before I start messing with regexp though I thought I'd see if there were any pre-built functions or ways of doing this? I'm building a site search and have not found anything in the docs but am guessing there might be an easier way of proceeding? Many thanks... - -- Nick Wilson // www.explodingnet.com -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.6 (GNU/Linux) iD8DBQE9E5dUHpvrrTa6L5oRAtrRAJ0YqRvKl8WAAG9xYiFHa6u0Nr7RYgCcDIii A/dUb7p9De0J1huL+e2QPFs= =03Ln -END PGP SIGNATURE- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This looks like a great example to add to weberdev. If you get this working, would you care to spend 3 minutes and let other PHP developers enjoy from your experience? You are one click away from doing a good deed :) http://www.weberdev.com/index.php3?GoTo=addexample.php3 Sincerely berber Visit http://www.weberdev.com Today!!!

Re: [PHP] getting anchor tags
PHP.net has some good examples if you search under the regex functions. Or
you might use something like the function below. I wrote this in a search
engine spider. It will return a list of local html links found on the given
page. The way I used this in my spider was to build a master list of local
links and test that against a separate array of visited links. Combine with
a little Javascript you can index an entire website with visual feedback.
function extract_links($url)
{
$fp = fopen($url, r);
if ($fp !== false)
{
fclose($fp);
$contents = implode(, file($url));
preg_match_all(|href=\?([^\' ]+)|i, $contents, $arrayoflinks);
foreach ($arrayoflinks[1] as $link)
{
// Trim out any links with http://
if (!ereg('http://', $link))
{
// Make sure the links are html files.
if (ereg ('.htm', $link))
{
// Build array of local links on this page.
$links[] = $link;
}
}
}
$links = array_unique($links);
$links = array_values($links);
return $links;
}
else
{
return false;
}
}

Hi
In theory I can work out how to get a href= tags from a page. Before I
start messing with regexp though I thought I'd see if there were any
pre-built functions or ways of doing this?
I'm building a site search and have not found anything in the docs but
am guessing there might be an easier way of proceeding?
Many thanks...
