Question

How do i get all defined global variables inside a class function?

When I call the get_defined_vars() function inside a class method I only get an empty object.

Answer 1

via => Define variables outside the PHP class

class Foo {
    function bar(){
       var_dump($GLOBALS);
    }
}
Foo::bar();

outputs :

array(8) {
  ["GLOBALS"]=>
    array(8) {
      ["GLOBALS"]=>
      *RECURSION*
      ["_POST"]=>
      array(0) {
      }
