PHP referrer domain and subfile -

i have code:

$allowed_host = 'domain.com'; $host = parse_url($_server['http_referer'], php_url_host);  if(substr($host, 0 - strlen($allowed_host)) == $allowed_host) {   echo "ok"; } else {   echo "not ok";   exit(); } 

this code based on domain how can check domain , php file?

if referrer page: domain.com/fromok.php {echo "ok";} else {echo "not ok";} 

your code give 'ok' if request host name ends 'domian.com', example if 'adomian.com'. assume don't want it.

you can use

$allowed_host = 'domain.com'; $allowed_path = '/fromok.php'; $url_components = parse_url($_server['http_referer']);  if((($url_components['host'] === $allowed_host) || (substr($url_components['host'], - (strlen($allowed_host) + 1) === '.' . $allowed_host)) && ($url_components['path'] === $allowed_path)) {   echo "ok"; } else {   echo "not ok";   exit(); }
