Dynamic Parameters (Using Reflection)
Description
Allows for you to call a method of a class with the parameters in no particular order! Example:
function print($string, $size = 12, $color = 'red);
If you want to skip size, but you want to change the color... that is exactly what this class will do... eg...
$machine->call('print', array('string' => 'hello world', 'color' => 'green'));
And the optional size value will simply get passed a null,which will result in the default value of 12 being used ;-)
Have fun.
P.S. The original idea (though no code here is based off this) came from: http://www.phpclasses.org/browse/file/25345.html
Technical
Requires PHP 5.2 or something... basically a recent version of PHP 5 :-D
To use the class... see the examples below it in the source code. The class just needs to be inherited by any classes wanting to use it, and then call it's "call" method to use it's power :-D
When all the code below is run, it will show the following on your browser to demonstrate it works:
hello world
Fatal error: The parameter "string" is required! in {location of file} on line 78

Gotta say I have no idea WHERE or WHY the hell this would be used, but still a
pretty interesting piece of code, none-the-less.

Hi ya gunni,
Yeah i should really have done, eval is evil (plus error messages are messed up in
it). But eval came to mind first and to be honest, this is only a quick script anyway
so i'm not updating i anymore unless i get an urge to. It would need optimizing
and more work adding to it before it's of any real benefit to anyone.
If you want to improve it, feel free.
Kind regards,
Scott

you should really prefer call_user_func_array() instead of eval() . And call() should
return the return value of the method called.

Damn, looking over my code, i think i've spelt parameters wrong every time! lmao

Haha, i'm never sure where anything comes in handy but i learn it anyway. I
never new reflection would come in handy lol
Kind regards,
Scott
