right - because the following code is totally valid and reasonable even i=

"my_function" will later get a fourth param $d=3D'default' and the strict=
 warnings
here forcing you to disable E_STRICT with  the negative impact losing use=
full
strict-warinings or rewrite tons of code after changes in a extended clas=
s with a
new optional param

someone who is using "my_b" needs not to know anything about "my_a" which=
 usually
is in a foreign file and often an external library

<?php
 class my_a
 {
  public function my_function($a, $b, $c)
  {
   echo "$a, $b, $c";
  }
 }

 class my_b extends my_a
 {
  public function my_function($a)
  {
   parent::my_function($a, 'internal default b', 'internal default c');
  }
 }

 $instance =3D new my_b();
 $instance->my_function('test');
?>
