Fetching the title of a webpage.

manjit

Just found out the get_meta_tags() function but i couldn't find a way to fetch a webpage's title other than fetching the whole page and parsing through line by line.
Or am I just missing out on another cool function ?

There isn't such a function.

Consider looking into regular expressions:
www.php.net/eregi
www.php.net/preg_match

And into string matching:
www.php.net/stristr
www.php.net/strpos

Or into a function I've made to do similar things:

This should do what you want using regular expressions.

<?
if ($submit):
$tags = fopen("$data", "r") or die ("Could not open page");                         

$r = fread($tags, 300);   

$r = strtolower($r);
preg_match_all("/<title>.*?\n/", $r, $matches);
$take_out =Array('<', '>', '/', 'title');

$matched =($matches[0][0]);

            if(eregi("title", $matched)):

$title = str_replace($take_out, "", $matched);       

print"<hr>This is the page title :: <b>$title</b>";
                else:
        print"<b>Sorry, I could  not get the title for this page</b>"; 
                endif;
else:
print"<html><title>Find Title</title>
        <body>
        <form method=\"POST\" action=\"$PHP_SELF\">

    <table width=\"300\" border=\"0\" align=\"center\">
    <tr><td>Enter URL !!</td></tr>
    <tr><td><input type=\"text\" name=\"data\" value=\"http://www.homestarrunner.com\" size
=\"34\"></td></tr>  

        <tr><td><input type=\"submit\" name=\"submit\" value=\"Get Title\"></td></tr>
        </table>
        </form>
        </body>
        </html>";
endif;
?>
