Mehea, in PHP if you pass a variable by reference that hasn't been created, PHP will create it.
See example 1:
http://au2.php.net/manual/en/language.references.whatdo.php
So $arg as a optional parameter in:
my_func(&$arg = 22) {}
...would create a variable that references itself, when every call to my_func() is made.
