There are other ways. `exec` might work fine though. Is something not working for you currently? Are you worried about some injection? – user3783243 Jun 09 '18 at 23:51

What are the other ways, I am going to communicate with a command line application, and I want a method that has little to no overhead – yabo Jun 09 '18 at 23:53

For example using exec I expect will open a cmd.exe program all the time to execute these commands (The same with linux) – yabo Jun 09 '18 at 23:54

You might want to check that exec is enabled on the server, on some servers it might be disabled – SpacePhoenix Jun 10 '18 at 00:16

What do you mean "outside program"? Another process on the same server? A process on a different server? API? You need to elaborate on what you're trying to do – Machavity Jun 10 '18 at 00:20
