[PHP] Re: Please Help - getting a hightlight depending on selected page

[Gabe da Silveira]

Okay, well you could either put code like this into each td cell like 
this:

<td class="navtext" <?php if (sect == 5) print "id=\"sel\""; ?>>

That is kind of ugly, however.  A more elegant solution would be to make 
an array containing the links then do a loop kind of like this (I'm just 
typing the code off the top of my head, so there is likely to be some 
errors):

$menuItems = array('Home', 'Introduction', 'Changes &amp; Cuts', 
'Scores', 'Orchestra', 'Synthesizers', 'Sound System', 'Articles');
$i = 0;
foreach ($menuItems as $item) {
   if($sect == $i) {
      print "<tr><td class=\"navtext\" id=\"sel\"><a 
href=\"\">$item</a></td></tr>\n";
   } else {
      print "<tr><td class=\"navtext\"><a 
href=\"\">$item</a></td></tr>\n";
   }
   $i++;
}

The obvious problem with my solution is the links will also presumably 
have to be entered into an array, and I don't think the foreach 
construct can work on two arrays simultaneously, but you can use the $i 
variable as the index to your second array.
