Update: Security Fix, $count was not sanitized, now fixed! Enjoy.
Update: Works now with 4.2+ (register_globals change). Updated form validation (security). PHP-Ping is a PHP script to ping from your server. The author writes "I was looking for a easy ping script and didn't found one, so I wrote this one. Just one file, a single line to configure.". Update (Aug. 2002): no more errors with new PHP versions.
