[SOLVED] Get title?

[ki]

How do you get the title of a(n) external webpage? Ive seen it done on the vBulletin's software. Anyone know how to exactly do this? Or is there a PHP function already added to the PHP software that I don't know about.

Probably not the best way:

<?php
$res_link_1 = 'http://www.phpfreaks.com/';

$file_1 = file_get_contents($res_link_1);

preg_match('#<title>(.*?)</title>#s', $file_1, $matches[]);

echo '<pre>';
print_r($matches);
echo '</pre>';
?>

Taken from PHP.net:

 

<?php
$file = fopen ("http://www.example.com/", "r");
if (!$file) {
    echo "<p>Unable to open remote file.\n";
    exit;
}
while (!feof ($file)) {
    $line = fgets ($file, 1024);
    /* This only works if the title and its tags are on one line */
    if (eregi ("<title>(.*)</title>", $line, $out)) {
        $title = $out[1];
        break;
    }
}
fclose($file);
?>

parser the index file of the site and read the title in

<title>blar</title>

 

something like this

 

<?php
$HTML = file_get_contents("http://www.phpfreaks.com");
preg_match_all('%<title>([^<]*)</title>%i', $HTML, $result, PREG_PATTERN_ORDER);
$result = $result[0];
echo $result;
?>

 

EDIT:

LOL,

and the winner is haaglin, for his snip from PHP.NET, which proves better that the other two LOL

Thanks guys, they work fine. Does this effect bandwidth at all? And if so, which one if more effective?

[MadTechie]

the best one for, speed and bandwidth as it, stops when it finds the title..

the other read in the whole page..
