Hello everybody, so iam going to show you Today how to Check for TCP Listening Ports's Validation and Status using a small PHP script.

1. We have to initializate some required vars:
          $host = "127.0.0.1"; // The Device's remote host which will be used on Monitoring the Specified Ports. $timeout = 2; // The connection timeout. (in Seconds) $ports = array(80,21); // The specified Ports which will be Monitored. $datei = fopen('portlist.ini', 'w+'); // Creating/Overwritting a file which will be used to store in the Data.
2. Let's Add the Tagline of your Logs File(portlist.ini or whatever):
   fputs($datei, "[Ports]\r\n");
3. Lets initializate a Loop Statement which will be used on switching between your specified Ports:
   for($i = 1; $i <= count($ports); $i++){ $a = $i - 1; // it subtract a number ever time. and assign the result to the var $a
4. Let's Set the Variable's Type to Integer to avoid some stupid warnings/errors which will be caused of 'int to str':
   settype($ports[$a], "int"); // for more info about possible Types feel free to check http://php.net/manual/en/function.settype.php
5. Let's do the Magic:
   $print = "Port".$ports[$a]."=" . ($handle = @fsockopen($host, $ports[$a], $errno, $errstr, $timeout) ? 'OPENED' : 'CLOSED') . "\r\n";
6. Let's Write the results to your INI Logs file:
   fputs($datei, $print);
7. Let's Close the Socket Connection to avoid Connection issues during the loop process:
   @fclose($handle);
8. Let's Close the Loop Statement's Bracket:
   }
9. Let's Close your INI Logs File's Process:
   fclose($datei);

Full Code:

PHP Code: (Select All)

       $host = "127.0.0.1";
 $timeout = 2;
 
 $ports = array(80,21);
 $datei = fopen('portlist.ini', 'w+');
 fputs($datei, "[Ports]\r\n");
 for($i = 1; $i <= count($ports); $i++)
 {
 $a = $i - 1;
 settype($ports[$a], "int");
 $print = "Port".$ports[$a]."=" . ($handle = @fsockopen($host, $ports[$a], $errno, $errstr, $timeout) ? 'OPENED' :  'CLOSED') . "\r\n";
 fputs($datei, $print);
 @fclose($handle);
 }
 fclose($datei); 


Thanks @Zorono : i really need this to check all active /inactive tcp connections. let me check it and then i gives you feedback.
