Are abstract class constructors not implicitly called when a derived class is instantiated?

Question

Take this example:

abstract class Base {
    function __construct() {
        echo \'Base __construct
\';
    }
}

class Child extends Base {
    funct         


        

Answer 1

If you need the same behaviour as C#, that is the parent constructor gets always executed before child constructor, you could create a fake constructor class for your child classes and declare it as an abstract function in your abstract parent class.

E.g.

abstract class Test{
  abstract public function __childconstruct();
  public function __construct(){
    echo "SOME CODE".PHP_EOL;
    $this->__childconstruct();
  }
}

class TestExtended extends Test{
  public function __childconstruct(){
    echo "SOME OTHER CODE FROM EXTENDED CLASS".PHP_EOL;
  }
}

$a = new TestExtended();

/* SOME CODE
   SOME OTHER CODE FROM EXTENDED CLASS */
