Code to return web path + title of page?

tuco

Hello,

Can someone help me with what I think is a simple bit of code?

On an arbitrary web page, I would like the code to return the web path to that page and including the title of that page.

The purpose is to provide folks who might want to link to the page the actual code they need to make the link by cutting and pasting the code into their own site.

Something like this:

<a href="http://www.phpbuilder.com/example.php">Page Title</a>

If the page title (in the <title></title> tag) is dynamically generated, say, from a text file or database, just use whatever that variable is when creating your link code. Such as:

echo "<a href=\"http://$_SERVER[HTTP_HOST]$_SERVER[PHP_SELF]\">$pageTitle</a>";

If not, and the <title></title> contents are static, you might have to rely on some type of javascript to retreieve it and put it into the link once the page loads.

Very nice. That works!

Can you think of a way that PHP can extract an existing (static) Title tag from the page and insert it into the code you have provided?

Ultimately, we do plan to assign the Title with variable, but right now, I'm just trying to make it work as a demo of sorts on a normal .php page.

Getting the page title requires loading the page, parsing the HTML and extracting the title.

So something like:

 // Assume $url contains the page address
 $content = file_get_contents($url); // Assumptions: allow_url_fopen is on, you have some nice global error handler
 $dom = DOMDocument::loadHTML($content); // Assumption: document is either in latin1 or contains a meta http-equiv content-type tag
 $titles = $dom->getElementsByTagName('title');
 $titlenode = $titles->item(0); // Assumption: There is at least one title element on the page
 $title = $titlenode->nodeValue; // Assigns title, IN UTF8 REGARDLESS OF PAGE ENCODING!
 // NB: DOM works internally in utf8 regardless of the encoding of the original document or your page.

See?

Some pages I recommend you test it on:

http://www.pravda.ru/
http://news.bbc.co.uk/hi/arabic/news/

If it gets the Arabic right from BBC Arabic and the Russian right from Pravda, it probably works.

Here's some javascript that would work.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Bling Bling!</title>
<script>
function GetTitle()
{	
	document.getElementById("link").innerHTML = document.title;
}	
</script>
</head>
<body onload="GetTitle();">

<a href="http://(PHP URL HERE)" id="link"></a>

</body>
</html>

I only tested this in Firefox 2 and IE 6, so I'm not sure how well it will work with other browsers.
