ever like this: 
                  
                  
                  Type your answer here [         ] thanks! 
                  
                  
                  so user's terminal cursor goes after [ and users answer will starts typing from there!
                  
                  
                  it can be helpful if you wanna set answer length!
                  
                  
                  following function can help you!
                  
                  
                  
                  
                  
                  function posReadline ($prompt=null, $len = 1, $force = false) {
                  
                  
                      $pos = strpos($prompt, '%s');
                  
                  
                      if($pos !== false) $prompt = sprintf($prompt, '[' . str_repeat(' ', $len) . ']');
                  
                  
                      $back = $pos ? strlen($prompt) - $pos - 1 : -1;
                  
                  
                      prompt:
                  
                  
                      echo $prompt . "\033[".$back."D";
                  
                  
                      while (($res = fgets(STDIN)) === false) {
                  
                  
                          usleep(10);
                  
                  
                      }
                  
                  
                      $res = str_replace(PHP_EOL, null, $res);
                  
                  
                      if ($force && strlen($res) !== $len) goto prompt;
                  
                  
                      return $res;
                  
                  
                  } 
                  
                  
                  
                  
                  
                  you can using like this:
                  
                  
                  $input = posReadline('Insert your answer: %s ,Thanks!', 6, true);  
                  
                  
                  
                  
                  
                  if you set $force to true (just like the example) user must enter an answer with the given asked length!
                  
                  
                
Thanks
