To extend on Samer Ata and Simon Rodan's answers, you can use the following to be able to execute any function with any amount of arguments:

if(isset($argv[1]) && function_exists($argv[1])) {
  $parameters = array_slice($argv, 2);
  call_user_func($argv[1], ...$parameters);
}

This is done by removing the script and function name from $argv and then using the spread operator (...) to interpret each element in the array as an argument to call_user_func.

The operator is supported from PHP 5.6 onward (and 5.5 can do some of the things using functions). You can read more about it in the official PHP documentation. For completeness, this is also known as argument unpacking.
