PHP: __construct() question

Hello php gurus

If a class has a method named after the class, is the function constructor?
If I have a base class as

PHP Code:

---

// Inheritance test
class Animal
{

    function __construct($ref)
    {
        $this->animalName = $ref;
    }

    function eat()
    {
        printf("%s is eating<br />", $this->animalName);
    }

    protected $animalName;
    
} 


---

and I'd like to call the base's constructor in the derived

PHP Code:

---

//
class Panda extends Animal
{
    function __construct($ref)
    {
        $this->Animal($ref); //works only if Animal($ref) is defined in the base
    }

    function eat()
    {
        printf("Big %s is eating<br />", $this->animalName);
        return $this;
    }

    function yawn()
    {
        printf("Big %s is yawning<br />", $this->animalName);
    }
}

What is the difference between __construct() and the function with the same class name?

Thanks for the help.

If no constructor method is found, then a function that has the same name as the class itself becomes the constructor.

I see.
Then, how do I initialize base member in the derived class
when the base class only uses __construct?
because $this->__construct($ref); doesn't work.

You could just create a new instance of the class and then unset it.

Hm, does that mean a ctor with the same class name serves as a better base class ctor
than __construct() when the dervied class has the need to intialize its base members?


Is that the only difference between the named ctor and __construct()?

The child class (panda) can call the parent's constructor using:

PHP Code:

---

parent::__construct($ref)
