Php coders I need help with these codes

[cruzades]

radius_database = /sr/local/etc/raddb/users  //this is the record of all radius users 
cp_database = /var/db/captiveporta.db        //this is the record of logged-on clients

radius_user = count(radius_database)
cp_users = count(cp_database)

for i = 1 to len(radius_user)
	if radius_user[i][expiration] = today
		for ii = 1 to len(cp_users)
			if radius_user[i][username]=cp_users[ii][username]
				captiveportal_disconnect_client(cp_users[ii][userid]
			endif
		next ii
	endif
next i

close databases

I will be using this in terminating current logged-on users if their account is expired at 00:00hrs.

thanks and more power
