PHP: get_called_class() returns unexpected value
Question by J.S.
Using PHP 5.3+ and having something equal to the following I get the output of ‘C’ instead of ‘B’:
class A
{
public static function doSomething()
{
echo get_called_class();
}
}
class B extends A
{
public static function doMore()
{
self::doSomething();
}
}
class C extends B {}
C::doMore();
If I had used static::doSomething() that would be the expected result, but when using self::doSomething() I expect this method to get called in the scope of B because it’s where the ‘self’ is defined and not the late static binding.
How is that explained and how do I get ‘B’ in the doSomething() method?
Thanks in advance, JS

Override the method doSomething, to get B
class C extends B
{
public static function doMore()
{
B::doMore();
}
}
Tested
