function generate_ratings($review_rating)
{
     for($i=0;$i<review_rating;$i++)
     {
          $movie_rating .= "<img src='thumbsup.gif'>&nbsp;";
     }
     return $movie_rating;
}

The part that really throws me is the 'for' with its arguments. I don't get the three arguments. I need it in English.

for is like a while().. loop, but with a predetermined number of cycles.

broken down, this example,

$i=0; (start with $i equal to zero)
$i<$review_rating (loop until $i is equal to or greater than $movie rating)
$i++ (increment $i by one each cycle)

and equivalent while() loop would look like:

$i = 0;
while ($i < $review_rating)
{
  $movie_rating .= "<img src='thumbsup.gif'>&nbsp;";
  $i++;
}
return $movie_rating;

Thanks, that makes a lot more sense now.

Everybody knows that a function returns a value. Exactly WHERE - what line - does the function return that value?

Does the line 'return $movie_rating' return the value?

Which line of the code instructs the CPU to return to the 'for' line for another iteration?
