Bug description: introducing default params values in overridden methods
throws E_STRICT
Description:
------------
Introducing a parameter with a default value in a function of a derived
class, where the function in the parent does not have a default value,
throws an E_STRICT.
Introducing a default does NOT change the function's signature and should
not cause any problems. It is possible in C++ and most other OO languages
without any issues. In PHP it causes an E_STRICT to be thrown.
This is especially an issue when working with third party libraries (i.e.
Smarty) that need to be overridden to have defaults (i.e.
display()/fetch()). This works fine, but does throw an E_STRICT.
Reproduce code:
---------------
class Parent
{
public function foo($bar)
{
}
}
class Child extends Parent
{
public function foo($bar = "test")
{
}
}
Expected result:
----------------
No E_STRICT thrown
Actual result:
--------------
E_STRICT thrown
