Yes you can do it like that but you should reference the arguments from the $_SERVER['argv'] array. $_SERVER['argc'] will tell you how many args were received, should you want to use that as a first layer of validation to make sure a required number of args were input.

To illustrate this, running the following script as args.php arg1 arg2 arg3:

#!/usr/bin/php

will output:

array(4) {
  [0]=>
  string(8) "args.php"
  [1]=>
  string(4) "arg1"
  [2]=>
  string(4) "arg2"
  [3]=>
  string(4) "arg3"
}

Here is a practical example:

In this example, we'll create a script (days.php) that outputs the number of days since a particular date. It will accept 3 parameters, the month, day, and year as numbers.

#!/usr/bin/php

Shell call:

`$ ./days 11 17 1988` OR `php days.php 11 17 1988`

Output:

7699 days since 11/17/1988

Hope this helps.
