$argv in a class

Question

I'm using exec() to exec a file but the file is in a class, I read more about argv but it was confusing. I need to get it to work inside a class.

It says:

Please note that, $argv and $argc need to be declared global, while trying to access within a class method

_{on php.net}

Answer 1

That means argc/argv aren't superglobals - they're only visible at the top-level context of PHP scripts, so...

<?php

$x = $argv[1]; // works

class foo {
   function bar() {
       echo $argv[1]; // undefined
   }
   function baz() {
       global $argv;
       echo $argv[1]; // works
   }
}
