Question

When I check apache_request_headers() I found PHPSESSID .

$headers = apache_request_headers();

foreach ($headers as $header => $value) {
    echo "$header: $value <br />\n";
}

results something like this.

Host: localhost.com

How do I turn off the PHPSESSID and why it's appear on every page by default?

If you want to turn off using cookies in sessions, you can set the PHP ini directive session.use_cookies to 0 . See the manual .
