Why use strings when doing rules for Form Validation instead of flags

[eluser]ocdcoder[/eluser]
The "other frameworks" wasn't so much about validation in other PHP frameworks, but about frameworks dealing with "dynamic" parameters. jQuery, being js and not php, uses objects like: $.func({param1:val, param2:val}); I have also seen (and used by preference) php this way as well:

Code:

myFunc(array('param1'=>val, 'param2'=>val));

or (to put in form validation terms):

Code:

$this->form_validation->set_rules("email", "email", array('trim', 'required', 'valid_email'));

for example.

I guess I'm just not a big fan of playing with strings like they're arrays (even though they technically are, but you know what i'm talking about). Oh well, I may go modify the library later, but not right now. I was more just curious about the coding convention than anything else. Thanks for the replies!
