Creating FTP account in cpanel and DirectAdmin via php

Hi, I have two PHP scripts one for CPanel and one for Directadmin to create user account via PHP The code for Cpanel is I want to add FTP account in the created new account which will be redirected to /public_html just before the line echo "Done"; I just would like to know how to do so ? Now for directadmin the script is like this $url= "https://$server_login:$server_pass@$server_ip:2222/CMD_API_ACCOUNT_USER?username=$username&email=$email&passwd=$upass&passwd2=$upass&domain=$domain&package=plan&ip=$server_ip&add=Submit&action=create"; $result = file_get_contents($url); echo "Done"; The same question how to add FTP account in the created new account before echo "Done"; ?
