Port scanner on PHP

port_scanner.php

<?php
ini_set('max_execution_time', 0);
ini_set('memory_limit', -1);

$host = 'google.com';
$ports = array(21, 25, 80, 81, 110, 143, 443, 587, 2525, 3306);

foreach ($ports as $port)
{
    $connection = @fsockopen($host, $port, $errno, $errstr, 2);

    if (is_resource($connection))
    {
        echo '<h2>' . $host . ':' . $port . ' ' . '(' . getservbyport($port, 'tcp') . ') is open.</h2>' . "\n";

        fclose($connection);
    }
    else
    {
        echo '<h2>' . $host . ':' . $port . ' is not responding.</h2>' . "\n";
    }
}

Thank you. Very helpful.

hello , this is an old thread but im curious to know how to put the url as variable and all in a loop
so the script is able to process many URL from a .txt
thanks for the help

@crypto-maniac I think you should try to google a little bit before asking for help (cause you would have figured it out if you tried), but here's some code to get you started:

$document = file_get_contents('urls.txt');
$hosts = explode(PHP_EOL, $document);
$ports = [21, 25, 80, 81, 110, 143, 443, 587, 2525, 3306];

foreach($hosts as $host){
	//just copy pasta from line 8 to 22
}

Congratulations on the code, it helped a lot but I have a problem when testing port 3389 rdp, could you help me?

Example: I want to check for 100 IP addresses, with 3 ports 20, 40, 60. Can anyone help me with a complete code to run the check port loop of 100 IP addresses? Thanks everyone
