Are there any specific PHP functions or methods that can be used to identify search engine robots?

To identify search engine robots in PHP, you can use the `$_SERVER['HTTP_USER_AGENT']` variable to check the user agent string of the incoming request. Search engine robots often have specific user agent strings that can be used to identify them. 

$user_agent = $_SERVER['HTTP_USER_AGENT'];

if (strpos($user_agent, 'Googlebot') !== false || strpos($user_agent, 'Bingbot') !== false) {
    // This request is from a search engine robot
    // Add your logic here
}
