PHP Spy uses PHP to show your IP address, browser, OS (operating system), and ISP (Internet service provider). In addition, if you came to this page my clicking a link, PHP Spy will show the URL of the referring page. The information gathered by PHP Spy can be highly useful when used with a counter to store statistical information about visitors.
