One button:

button id='go'

and one div.

User writes a site in that input and onclick i must show title of that site

How can i do that ?

From what you told me, here's some code.

<?php
    if (!isset($_GET['go'])) {
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="GET" />
<input type="text" name="url" id="url" /><br /><input type="submit" name="go" id="go" />
</form>
<?php
} else {
$url = $_GET['url'];
$file = file($url);
$file = implode("",$file);

if(preg_match("/<title>(.+)<\/title>/i",$file,$m)) {
    print "The title of $url is <b>$m[1]";
} else {
    print "The page doesn't have a title tag";
}
}
?>

This downloads the file into the PHP memory and gets the information between the title tags.
