how to get all post data

[eluser]Arun Joshi[/eluser]
I have a dynamically built form. And there is lot of controls. I cant define each controls name initially. In this case when I submit form, how can i get all the post data from that form?

similarly

Code:

var_dump($_POST);

.

I searched in the form. But cant find a solution for this.

Thanks
Arun
