    I'm a php noob.

    Is there a superglobal that tells which keywords the visitors that came from search engines are?

    Say a visitor searches for "apples" on google, how can i implement that keyword using php?

if (preg_match('~[&\?]q(?:uery)?=([^&]+)~', $_SERVER['HTTP_REFERER'], $keywords))
{
    echo $keywords[1];
}
    PHP:
    This should do it... it's untested though.
