[RESOLVED] New to OO help

I'm having problems figuring out how to put two arrays in to a single string while running them through a for loop any help would be appreciated. I'm creating of course a mysql class of functions to use with my website. If you need more info let me know but I think this is a pretty straight forward approach.

	//Update Database Record Function
	function Update(){
		$this->call = "UPDATE ".$this->table." SET ";

	if(is_array($this->fields)){ //Checks to find out if there are multiple fields that need update
		$this->total = count($this->fields); //Counts the number of fields

		for($i=0; $i <= $this->total; $i++){
			$this->set = $this->fields[$i]."=".$this->field_val[$i].",".$this->set; //PROBLEM AREA
		}
	} else {
		$this->set = $this->fields ."=". $this->field_val;
	}

	$this->sql = $this->call."".$this->set." ".$this->WHERE_statement." ".$this->table_var."="$this->where; 

	mysql_free_result($this->trustinmetcg);
}

I figured it out I'm a little slow I don't know why I didn't want to use an if statement to solve the problem the resolution is:

			for($i=0; $i <= $this->total; $i++){
				if(isset($this->set)){
					$this->set = $this->set.","$this->fields[$i]."=".$this->field_val[$i];
				} else {
					$this->set = $this->fields[$i]."=".$this->field_val[$i];
				}
			}
