How can PHP be used to verify if clicks come from a specific page?

To verify if clicks come from a specific page using PHP, you can check the HTTP referer header in the incoming request. This header contains the URL of the page that linked to the current page. By comparing this URL with the specific page you want to verify, you can determine if the click originated from that page. 

if(isset($_SERVER['HTTP_REFERER']) && $_SERVER['HTTP_REFERER'] == 'http://specificpage.com') {
    // Click came from the specific page
    echo 'Click verified from specific page';
} else {
    // Click did not come from the specific page
    echo 'Click not verified from specific page';
}
