Foreach in Chapter 6

I am confused about the use of the foreach loop described in the movie.php file in chapter 6:

PHP Code:


			
//populate the select options with the results
while ($row = mysql_fetch_assoc($result)) {
   foreach ($row as $value) {
     echo '<option value="' . $row['movietype_id'] . '">';
     echo $row['movietype_label'] . '</option>';
  }
}

Why are we using a foreach loop? We are assigning values to $value and then not calling the variable in the loop; we end up calling the specific $row array values instead... this just causes everything to be repeated twice in the drop down menu.

Is this a mistake?

Thanks in advance for the help...

I have removed the foreach loop and the code displays correctly in the browser...

If there was some purpose for the foreach, please let me know.

Thanks,

Thanks, I've been working my way through the book and had thus far been able to solve every problem, but just couldn't figure out how to make the foreach work for this. Never though to just remove it, figured it was there for some reason.
