capturing hyperlink page's tittle

yipguseng · #1 (**permalink**) 12-02-2007, 09:56 AM

was been wondering again, sometimes when i enter the url for a page, then when it is display, it will show the title of the target page's title as the anchor name instead of the url, think this is quite nice and cool function

....anybody knows how to do it?

and btw, why is it sometimes it capture but sometimes it did not? is it that it can't capture dynamic page title?

PHP Code:


			
<?php

$post="here is the post you want to add....";

//1. Recognise the links!

if (preg_match_all("/http[s]?\:\/\/[^ ]+/ism",$post,$matches))

{

  //loop through matched links

  foreach ($matches as $link)

  {

    if ($fh=fopen($link[0],"r"))

      {

      $p=fread($fh,4096); // 4096 should be enough to get the <title>

      if ($m=preg_match("/\<title\>(.*?)\<\/title\>",$p)) $post=str_replace($link[0],"<a href=\"$link[0]\">$p[1]</a>");

      }

  }

}

Something like that should work (untested). You will need to edit it if you want to support BBcode as well.
