How to retrieve link location from following script using preg_match

<html><head><title>Object moved</title></head><body>
<h2>Object moved to &l开发者_JAVA技巧t;a href="www.example.com">here</a>.</h2>
</body></html>

Thanks

First: if you are using CURL use

    <?php 
// ....
        curl_setopt($ch,CURLOPT_FOLLOWLOCATION) 
    ?>

else

Location is in header "Location:http.."

try to get headers by get_headers or parse this output by this pattern ,

$pattern = 'href=\"(?<url>[\"]+)\"'

If I understood it correctly, you simply want to extract the url, from your html code? If so, you can do it like this:

preg_match('/object moved to <a href="(.+?)"> here/,$html_text,$match');
$url = $match[1];
