How can PHP counters be modified to exclude search engine visits?

To modify PHP counters to exclude search engine visits, you can check the user agent of the visitor and exclude known search engine bots. This can be done by comparing the user agent string against a list of common search engine bot user agents. 

<?php
$exclude_agents = array('Googlebot', 'Bingbot', 'Yahoo! Slurp');
$user_agent = $_SERVER['HTTP_USER_AGENT'];

$exclude_visit = false;
foreach ($exclude_agents as $agent) {
    if (stripos($user_agent, $agent) !== false) {
        $exclude_visit = true;
        break;
    }
}

if (!$exclude_visit) {
    // Increment your counter here
}
?>
