get_defined_vars() inside a class

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.

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) {
      }

Use get_class_vars(__CLASS__) if you want the predefined variables & values (those values defined and set as default before an object initialized).

Use get_object_vars($this) if you want all the variables (instance variables) including those which are created temporarily for a particular object while executing any method of the class.

I know these are not really the things you need. Its $GLOBALS that you need answered yourself. But I just gave these methods for your reference so that may be useful in the future.

Maybe you can try get_class_vars()?

sorry maybe i had explain it wrong, i meant the wide site vars, like if get_defined_vars() was called in the main script. – markcial Mar 24 '10 at 08:54
I'm not aware of that being possible, because every function / method makes own scope. get_defined_vars() does return the variables defined in your class method, if you have any, but this is not helping you. – jholster Mar 24 '10 at 09:17
