Hi peejavery,
Sorry, I don't understand very well the question.
As you know, the way to specify a URL is done either
- by submitting a form whose action is to go to a specifed URL
- by sendind a header containing a URL : header("Location: my_url.php")
- by having an "href".
About the title tag, as you know, it is a meta tag included in the <head> section of a page. PHP knows it, if PHP has dynamically created that page, or PHP can know it by reading that page like if it were an ordinary file, and searching for the keyword "title".
Maybe, you wish that the title would appear, not only in the caption of the browser, but also in the URL field of the browser. This can be done if the server is configured to accept what is called "URL rewriting".
I think he wnats to look at a website, such as http://codeguru.com from his server, and use PHP to grab the title of the page. Me in particular, I don't know a solution.

than you could iterate through that array an search for the title tag.
another approach is to use file_get_contents.
file_get_contents returns the whole content of the target file into one single string.
if all went well, $aMatches[1] contains the pages title (PHP: preg_match - Manual).Code:$sContent = file_get_contents('http://de3.php.net/manual/en/function.preg-match.php');
if( preg_match( '/<title>(.*)<\/title>/mi', $sContent, $aMatches) ) {
print_r($aMatches);
}
