How to get <title> info from previous page?

[Allen4172]

I'm writing an a script where a user can click a link, and it'll bring up an email type prompt where they can email an article link of the story to a friend and so forth.

I see it all the time on other sites, but am curious how I would get the <title> or subject of that article dynamically? Any ideas or recomendations would be much appreciated :)

Hey Mike,
just pass the variable with the link:

[code]
<?php
$page = file_get_contents("page.php");
preg_match('!<title>(.*?)</title>!is', $page, $match);
$title = $match[1];
?>
<a href="emailpage.php?title=<?=$title?>">e-mail this article to a friend</a>
[/code]

that should do it

Thanks for the info :)

However, that begs the question, what if I won't always know the previous page? How would I get that info? As my site is a CMS that has hundreds of possible pages.

Well if you don't know the previous page, then how to you expect to be able to go to that page and get the contents of the title tag...?

That was my question. I am not wanting to install this manually on every page (doing this manually for hudnreds of pages is not practical). Like I said this is a dynamic type application, which means that I won't know the page. However I am thinking if there is a referrer type variable that I may use.

I found what I was looking for in $_SERVER['HTTP_REFERER']
