oop - Php, inheritance, late static binding, unexpected calling chain -

consider code:

class c {     public function get()     {         echo 'c';         static::get();     }      public function save()     {         self::get();     } }  class b extends c {     public function get()     {         echo 'b';         static::get();     } }  class extends b {     public function get()     {         echo 'a';     } }  $x = new a(); $x->save(); 

it echoes ca while expected cba

to work way want, reverse logic - save call static::get() start @ top of inheritence tree; , use calls parent::get() in each inherited class in tree (except base level) before echoing own output

class c {     public function get()     {         echo 'c';     }      public function save()     {         static::get();     } }  class b extends c {     public function get()     {         parent::get();         echo 'b';     } }  class extends b {     public function get()     {         parent::get();         echo 'a';     } }  $x = new a(); $x->save();
