Re: Newbie Help (CLASS WAR!)

I use classes a lot and don't have this problem. This is because the names of the class ( and thus the constructor name ) tends to be a noun and otherfunctions tend to be verbs, so I am don't have this kind of clash. I am VERY glad that PHP has classes and I use them alot. However .... <rant_mode> My biggest bug-bear with classes in PHP is the lack of a "super" operator There are times when I would really like to be able to do: class A {

    function DoStuff()
    {
       .....
    }

} class B extends A {

    function DoStuff()
    {
       .....
       $super->DoStuff(); // Calls the function in A
    }

} A "super" operator could allow a fixed name constructor ( like the "__new__" in Python ) and the parent constructor could be called using "super", which would eliminate Matthew's problem. </rant_mode> At 08:47 26/07/2001 +0800, Matthew Schubert wrote:

I was reading through the PHP manual and got to the section on constructors. <snip> class A { function A() {

    echo "I am the constructor of A.<br>\n";

} function B() {

    echo "I am a regular function named B in class A.<br>\n";
    echo "I am not a constructor in A.<br>\n";

} } class B extends A { function C() {

    echo "I am a regular function.<br>\n";

} } // This will call B() as a constructor. $b = new B; In PHP 3, the function B() in class A will suddenly become a constructor in class B, although it was never intended to be. The rule in PHP 3 is: 'A constructor is a function of the same name as the class.'. PHP 3 does not care if the function is being defined in class B, or if it has been inherited. This is fixed in PHP 4 by modifying the rule to: 'A constructor is a function of the same name as the class it is being defined in.'. Thus in PHP 4, the class B would have no constructor function of its own and the constructor of the base class would have been called, printing 'I am the constructor of A.<br>'. </snip> It says that when a new class B was made, that the class B would have no constructor, because the function B() was in the base class. Instead the class B was supposed to derive it's constructor from class A and output 'I am the constructor of A.<br>' When I tried this script, this did not happen and the Function B() was called as the constructor of class B, even though the function was in the base class...can anyone help to clear up this matter????? thanx -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
