What are some common methods for filtering out bot traffic from web access counts in PHP?

Bot traffic can skew web access counts and analytics data. One common method to filter out bot traffic in PHP is by checking the user agent string of the incoming requests. Bots often have specific user agent strings that can be identified and filtered out. 

// Check if the user agent is a known bot
function isBot($userAgent) {
    $botStrings = array('googlebot', 'bingbot', 'yahoo', 'yandex', 'baidu');
    foreach ($botStrings as $botString) {
        if (stripos($userAgent, $botString) !== false) {
            return true;
        }
    }
    return false;
}

// Filter out bot traffic
if (!isBot($_SERVER['HTTP_USER_AGENT'])) {
    // Increment web access count or perform other actions
}
