Is the double colon var resolution valid in an Argument?
 

^^title speaks for itself^^
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

PHP Code:

---

// yes yes, make the class etc etc
  class TesterS
  {
// Make a public constant so its open to the whole class(:S)
    public const test = "Its called a test";
    
    // Since that value is a Constant and is set we do this, but could this be done
     public function(self::test)
     {
     return self::test;
     }

// end james
  } 


---

This is well, pretty much a start where I am in Advanced Programming.. So

This is also speaking for parent::

*!*:-D*!*:-$:-@

Find the errors ;-)

UPDATE: oops sorry bout that >.< sorry

Is this a joke of some sort? 'cuz I really don't get it. First of all, the big mistake is that you don't have a name for your method. Next to that, why would you want to do what you just wrote? I don't even want to know whether that is valid or not (but I'm pretty sure it isn't). I would never want to write a function that gets a variable as a parameter and returns it unchanged, but rather just use the damned variable. Especially not with a class constant or static variable, which is always available from within the class is declared, with self::const/$static.

Other than that, you're crazy :-P

The simple answer to your question is, no. Trying to use a constant of any kind (class or global) will result in a parse error, "syntax error, unexpected T_CONST, expecting T_VARIABLE". The error is pretty self-explanatory, the PHP engine expects a standard, normal, garden-variety variable (a reference or otherwise) as an argument.

If you were to try this with a static variable (public static $test = ... and self::$test as the function argument) then you would also get a parse error, this time saying: "syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM, expecting '&' or T_VARIABLE". Again it's clear that PHP really, really only wants a regular variable in there (the T_PAAMAYIM_NEKUDOTAYIM is just a constant for the '::' or T_DOUBLE_COLON operator).

If you tried to use an object property as the argument ($this->test) then I think you can guess the likely outcome from the examples given so far. :-P

In short, you can only use a normal variable ($test) or reference (&$test) as arguments.

Okay, thank you.

I screwed the code up cause I was in a hurry.
