Don’t have an index in all your directory’s? Many people create a blank index.html file in every directory to prevent directory listing. It’s ok for a small website, but imagine if you have a website that has hundred or thousand directories.

The easiest way is to write a htaccess file, include the following line in your .htaccess file to deny access to all the directory listings, if there is no index file.

PHP Code:
Options -Indexes

PHP code to check whether a yahoo user is online or not

$id="victim_id";
$url = 'http://opi.yahoo.com/online?u=';
$data = file_get_contents($url . $id);
if (trim(strtolower(strip_tags($data))) != 'user not specified.') {
echo (strlen($data) == 140) ? 'online' : 'offline'; }
else {
echo trim(strip_tags($data));
} ?>
