passing variables to a class function

[cangeceiro]

so basically what i am trying to do is this....

I am writing a ballot/poll type system. I am keeping all of the questions in a mysql database so they are easily managed and maintained. now, when a user fills out this form it posts to a new script which calls a function that inserts everything back into a sql database.given that there could be any number of categories and questions, how do i pass this all back into a function?

form example

<form action="post.php" method="post">
Category 1
<input type=text name="category1[1]">
<input type="text" name="category1[2]">
</form>

post.php

<?

class poll {
  function insert2DB(???????????) {
//here is were i will insert it into the db
  }

Something like this:

class poll {
	var $_var1;
	var $_var2;
	var $_var3;
	function Init ( $var1, $var2, $var3) {
		$this->_var1 = $var1;
		$this->_var2 = $var2;
		$this->_var3 = $var3;
	}
}

but say $var4 suddenly becomes part of the equation. how would this dynamically be able to account for that variable?

Use an array to store the (arbitrary number of) vars.
