function access

[jimfog]

I have a created a class where in it you will find password hashing/checking functions...for example:

public static function hash($password) {	  return crypt($password,self::$algo.self::$cost .'$'.self::unique_salt());}

And this is the code where you apply the function to a password submitted by the user with a form:

  $pass_hashed = PassHash::hash($_POST['password']);

My question is why the code below is wrong-according to Netbeans IDE?

  $pass_hashed = PassHash->hash($_POST['password']); 

Since I am accessing the has function OUTSIDE the class why it is wrong. PassHash is the name of the class.

If it's a static method then you use :: to access it. You only use -> when you are access a method of an instantiated object, not a static class method. http://www.php.net/manual/en/language.oop5.paamayim-nekudotayim.php
