PHP get user information
<p>I made a website with a login script. Now there is some guy that makes false logins all the time. For example usernames like 'lfdjgh' and email addresses like jkgfhkjghf@dkhfkgh.com. I want to find out where this person is located etc.</p>

<p>Is there a way to find some detailed information about that user? Computer-name, Ip address, location, etc?</p>

<p>Thanks</p>
