Hi All,
Just a thought, but while working reciently with a few ECMA scripting
languages (eg: ActionScript in Flash MX), I uncovered the amazing uses
(especially from a security point of view) of variable functions.
For those that dont know, it allows you to assign a function to a
variable, rather than to declare it globally, for example:
<?php
function test ($param, $default=false) {
// stuff goes here
}
test("my param");
/* could also be written as */
$func_test = function ($param, $default) {
// stuff goes here
}
$func_test("my param", true);
/* removing a function could then be */
unset($func_test);
?>
Any form of variable or constant would be able to be used (eg: a function
inside of an array, or a class method as a property). This would allow the
very very simple usage of "getter-setters", as they are called in flash.
EG: You may have the properties $user->birthdate and $user->age, where you
want the age to be pulled dynamically. At the moment you have to define
$user->age(), but the following code could be used:
<?php
class user {
var $birthdate = "YYMMDDHH";
var $age = function {
// Code to get birthdate
$myAge = // .... // ;
// Return the age
return $myAge;
}
}
?>
This may or may not fit into the way PHP is going, but its just an idea -
and ideas have never been frowned upon, (nor should they be!)
I think that puts across the general gist of my suggestion... any thoughts
or comments on the idea?
