Just creat a php file such as “ok.php” and upload it to your website’s root directory, the ok.php should include the belowing contents:
<?php Echo phpinfo(); ?>
Now visit the address “your domain/ok.php, if you can see the following infomation:
cUrl.information X.X.X. （such as 7.12.3）
Those mean that the pathinfo is enabled and for safety reasons you should delete the ok.php after you finish your job.
