    Are you in the right directory? What does echo getcwd(); show? Commented Apr 22, 2015 at 5:48

  • @minitech My first command in the php script checks the contents of the current directory (in web browser output) and the terminal is executing the command correctly. Commented Apr 22, 2015 at 7:01

Your a.out may be expecting exactly three parameters, but is only given two. The third parameter will be empty in the exec call.

Try this:

$param3 = escapeshellarg(""); // Will make it "''" => empty but existing to a.out

Thank you for your reply. I made the changes. Size of array is 1 now but still I don't see any output. I have also attached the source file for a.out.
I also tried escapshellarg for param1 and param2 but still I don't see any output like in the terminal window. Good thing is now it shows that size of array is 1.
