title: Find specific port using command prompt
body: <p>Is it possible to find specific port using command prompt? I want to use the exec command in php to check if a port is open. The fsockopen function in php is very slow so i wanna try to use the cmd to check the port and see if that works better. I want to find if port 7878 is open.</p>
  
  <p>I do not wish to download any softwares, I only want to know if it's possible to do it directly in cmd. And if its possible i want to know how the command for it</p>
