What is the *proper* way to do something like this? (In short: I want a class to hide the class
constructor for all but a few chosen friend classes)
<?php
class PackageClass
{
static protected function _new($class, $args)
{
switch (count($args))
{
case 0:
return new $class();
break;
case 1:
return new $class($args[0]);
break;
case 2:
return new $class($args[0], $args[1]);
break;
case 3:
return new $class($args[0], $args[1], $args[2]);
break;
case 4:
return new $class($args[0], $args[1], $args[2], $args[3]);
break;
case 5:
return new $class($args[0], $args[1], $args[2], $args[3], $args[4]);
break;
case 6:
return new $class($args[0], $args[1], $args[2], $args[3], $args[4], $args[5]);
break;
}
}
}
class UnconstructibleClass extends PackageClass
{
protected function __construct($msg)
{
print($msg);
}
}
class ConstructingClass extends PackageClass
{
public function __construct()
{
self::_new(UnconstructibleClass, array("Und ich krieg dich doch!"));
}
}
new ConstructingClass();
?>
