Pretty neat, I never once thought of making one big parameter array....
I agree its all a matter of taste. It could be a personal inditement but
i've always found my OO code easier to extend and maintain than my
proceedural stuff.
I can only recommend you give a go in PHP and see if it makes a difference
for you.

you could do something like:
$parameters["options"] = "nowrap";
$parameters["heading"]["bgcolor"] = "black";
$parameters["heading"]["fontcolor"] = "white";
$parameters["global"]["font"] = "tahoma";
$parameters["global"]["fontsize"] = 12;
$parameters["column"]["total"]["format"] = "bold";
echo create_table($data,$parameters);
The difference is a matter of style.

this is nothing you can't do without OOP.

Maybe so, I never used it. To me, the main reason to use OOP is when
you're dealing with Java or something and native code is dealing with
your objects. For instance laying out widgets on a screen might need
that your widget extend Widget and have a draw() method.
I've never had a situation with php where I thought doing things this
way would make things easier.
