Is there a reason to repeat the setting of $section?

Instead of setting the $section variable in each 'if' statement, wouldn't this code be more appropriate for the "dry" methodology?


if($_GET["cat"] == "books"){
  $pageTitle = "Books";
} else if ($_GET["cat"] == "movies"){
  $pageTitle = "Movies";
} else if ($_GET["cat"] == "music"){
  $pageTitle = "Music";
} else {
  $pageTitle = $pageTitle;
  $section = $pageTitle; // if there is a $pageTitle set this will set $section
} else {
  $section = null; // if $pageTitle is not set $section goes to null

are there any draw backs to doing it this way?

Sounds good, but hard to say for sure since we can't see what you are replacing. It always helps if you give a link to the video.
