IP list port scanner from txt file

This script is used for scanning list of IP addresses specified in a text file. It is used by selecting a file and entering a port range you want to scan. It consists of two parts: the HTML entry forms and PHP scripts for processing. After a completed scan, script throws a list with open IP addresses.

List of IP addresses should look like this(in each row one address):

10.0.0.1
10.0.2.5
10.0.3.8
10.0.2.1
