Script to Kill only exact PID in Linux

vi SearchPID.php

<?php
  $port = $argv[1]; 
  if(!empty($port) && is_numeric($port) ){
  $pid = trim(shell_exec("lsof -t -i:".$port));
  if(!empty($pid)){
     shell_exec("sudo kill -9 ".$pid);
     echo "pid : ".$pid."  killed which is listened port : ".$port."\xA";
  }
  else{
     echo " [X] no such process found for pid : ".$port."\xA";
  }
  }
  else{ 
     echo " invalid pid \xA";
  }
?>

Example

Need to pass the port argument in this example.

for example

>sh KillTask.sh 8088

What it will do is , it will grab the exact pid of the process running on port 8088

Thanks!!!
