I’ll post the code too

* Simple Scan class (c) 2003 Michal Cumpl
*
* Description: Simple scanner class
*
*
* Constructor
*
* SimpleScan(" correct IP address "," connection time out in s")
*
*
* Functions
*
* portInfo(" port number ")
* - scan given port and store results in object variables
*
* mtime()
* - return current timestamp with microseconds
*
* Variables
*
* $ip ... Scanned IP adderess
* $port ... currently scanned port
* $timeout ... port connection timeout
* $numports ... number of scanned ports
* $openports ... number of open ports
* $portstatus ... current port status (true/false)
* $portresponse ... current port info (errorstring or fgets output)
* $starttime ... start timestamp
* $actualtime ... current port scanning time
* $totaltime ... total time of scanning in s
*
*
* Example usage
*
* $scan = new SimpleScan("127.0.0.1", 0.2);
* echo "Now scanning IP address ".$scan->ip."
";
* for($i= ; $i<=80 ; $i++)
* {
