cURL get_data($url) with absolute URL

Question

I'm using this code to get data using cURL

$url='http://example.com/'; //URL to get content from..
print_r(get_data($url)); //Dumps the content

/* Gets the data from a URL */
function get_data($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}

However, This code returns data with relative url. How can I get ride of this relative url & print with absolute url? May be with preg_replace.. But How ?

You mean you want to convert the links in returned data from relative to absolute? — Salman A, Jan 12 '12 at 08:10

Have a look at the HTML base tag. You should find it helpful if you want to let the browser do all the relative-to-absolute conversion:

$data = get_data($url);
// Note: ideally you should use DOM manipulation to inject the <base>
// tag inside the <head> section
$data = str_replace("<head>", "<head><base href=\"$url\">", $data);
echo $data;

Awesome! Just what I was looking for. – Haru Feb 01 '12 at 18:44
This returns a "Headers already sent" error in my site. What can I do about that? – jdhaar Dec 21 '13 at 10:01
+1 for good, simple solution that uses often-overlooked tags. – YOMorales Mar 24 '14 at 21:50

I think that you must to use a HTML parser like http://simplehtmldom.sourceforge.net/, and replace all links with the correct path.
